Morula slaps her ears flatly against her shoulders.
Whoooosh, thwack . . . Whoooosh, thwack . . . Whooosh, thwack . . .
Elephant air-conditioning, for a creature that produces enough heat to warm a small house. Elephants are pachy-dermed, thick-skinned. Some of Morula’s blood vessels are buried as deep as one-and-a-half inches under her skin. Since she doesn’t have sweat glands, her ears act like giant heat exchangers, regulating her body temperature. As her ears open, her body size increases by roughly one-fifth and her ears provide a huge area for thermoregulation. The air moving over swollen arteries on the surface of each ear cools her blood as much as nine degrees before it returns to her body.
I take a photograph of her ear in mid-flap. Where Morula’s ear attaches to her shoulder, wrinkles give way to rising rivers of blood, pumping five gallons per minute across the surface of her ears. The pattern of arteries on an elephant’s ear is as unique as a fingerprint, and often used for identification.
Whooosh, thwack . . . Whooosh, thwack . . . Whooosh, thwack . . .
The breeze she creates dies before it reaches me. I take off my cap and fan my own neck.
My teeny, itsy ears are built somewhat the same as hers are, with an upper rim of cartilage and a fleshy, lower lobe. But I don’t have an auriculo-occipitalis, an ear muscle the size of a weightlifter’s bicep. I can’t flap my ears. I can’t even wiggle them.
Whooosh, thwack . . . Whooosh, thwack . . . Whooosh, thwack . . .
In the late morning heat Morula’s ears are in constant motion.
Ears of African elephants resemble huge maps of Africa. Ears of Asian elephants flop forward at the top and hang like small, wrinkled outlines of India. Morula’s ears fold backward, giving them a smooth, tidy appearance, a map pressed flat. Although the ears of all elephants have a similar construction – cartilage covered by a thin layer of skin – Morula’s ears are roughly three times larger than those of her Asian kin. African elephants have the biggest external ears of all mammals, perhaps the biggest of all time. Each one weighs approximately one hundred pounds.
And no two elephant ears are the same. As pliable and soft as worn canvas, the leading edge of an elephant’s ear is often caught and torn on branches or by the tusks of other elephants. In Kenya I watched an adolescent flare her ear and trace its outline with her trunk like a matador holding out her cape. Backlit by sunlight, three perfectly round holes on its border reminded me of diamond studs. Nearby, a huge bull posed for my gulping camera as I shot an entire roll of film in less than two minutes. Only later, with the film developed and the prints in my hands, did I notice the edges of his ears were as scalloped as an old lace tablecloth.
Here’s a little fairy tale: Once upon a time, elephants lived to a rhythm of their own making. There were no elephants in captivity. They were captured only in legend, in song, painted onto walls of caves, etched on the flat sides of rocks. There were no elephants on reservations, in circuses, in sanctuaries, or zoos. No elephants were murdered solely for their tusks. They were not orphaned by the slaughter of their families, nor made to endure solitary confinement, leg irons, beatings, prods, and electric shocks. They were not enslaved. They were not used as vehicles of war. They were not made to wear radio collars, jeweled headpieces, or bear intricately carved wooden howdahs on their backs. They did not carry princes, or hunters, or loggers, or performers, or tourists. They were not forcibly relocated from the land of their birth. Most died of old age. Once upon a time elephants knew a landscape without fear, without fences, a landscape empty of humans. Once upon a time, elephants were everywhere.
It’s 5:30 a.m., overcast and dark, very dark. Driving to work from the country into town, I’m jittery and wide-awake after two cups of coffee. In fact, I might be the only one who is awake – I meet no other traffic. It’s the time of year when I go to work in the dark and come home in the dark. I live far enough north for hibernation.
The headlights of my car fan out before me and tap the tops of trees as the road rises beneath me to the crest of a small hill. As I reach the top and start toward the bottom, right in front of me, no time to brake, there is a wolf in the road. Full of surprise, his yellow eyes meet mine.
I drive right through him.
No contact, no impact.
Stunned, my mind searches for answers: That was a wolf! No, it wasn’t a wolf; you didn’t hit anything. But it was a wolf: long thin muzzle, gray and silvery ruff, rangy legs. It wasn’t a coyote; it wasn’t a dog; that was a wolf! It couldn’t have been a wolf, because it wasn’t there! No, it was there, I saw it! How could you see a wolf? They haven’t been here for a hundred years. If it wasn’t a wolf, then what was it?
Parallel universes? A hundred-year tear in a moment of time? Science Fiction? No, it was a wolf! I saw it!
I glance into the rearview mirror. Darkness, total darkness beyond the faint red glow of my tail lights.
Perhaps there is a wolf out there, loping away among dark trees, unnerved at his encounter with a huge two-eyed roaring monster that froze him in his tracks and disappeared at the moment it came close enough for him to smell its stinking breath.
We shake our heads, the wolf and I, trying to dislodge the strange scene, which disappeared as fast as it appeared. Two convergent creatures tangling out-of-sync, caught in a collision of lives, of timelessness, creating for both of us an instant of absolute astonishment. Above us, the whirling constellations leave fading paths across the sky.
I rock back and forth, toe to heel, toward the fire and away from it. My boots touch coals while stars crowd close around, peering over my shoulder, whispering ancient stories in my ears. Only moments earlier giraffes reflected the setting sun, but now their silhouettes fade, blur and disappear. Soon, out there beyond this fire, hyenas will make short work of bones.
In the darkness elephants are on the move, and almost without sound, except for the occasional rifle shot of a cracked branch. I wish I could hear condensed air – infrasound – soft rumbling kisses brushing my cheek. The compacted silence is completely full of presence, of huge milling bodies on padded feet. A herd of mountains relocates during the night while my thoughts swirl, embers stirred by wind.
Suddenly to my right, trumpeting, perhaps furious at being left behind, an elephant thunders by, an outraged trombone blowing past. I lift my head to follow the sound, but it’s my ears, not my eyes that see.
In the morning, no more than a half-mile from camp, we encounter a herd of sixty elephants. Nervous mothers guide their newborns away with their trunks, shield them from us with their bodies. Young punk males show off for each other, make small charges to see if our vehicle will bolt. Huge bulls, intent on mating, barge past like runaway cement trucks.
We sit in the middle of a herd. Two males give us a rear view of old men in baggy pants. A jumbo-jet sized matriarch leisurely crosses right past our front bumper. Her ears are perfect replicas of the map of Africa. Like fingerprints, no two elephant ears are the same. As pliable and soft as worn canvas, their leading edge is often caught and torn on branches and scrub. Hers has a neat, perfectly round hole near the bottom of Africa, right about where we are in Zimbabwe.
A young female strolls by, scans us as if we’re department store mannequins. She’s so close all I can do is snap a picture of her eye. She stops, blinks, and regards us with the air of a disinterested shopper. I look down at her feet, round in front, oval behind. The round one is about the size of a medium pizza pan. I glance back up, directly into her eyes. She stares back and shakes her head so hard that her ears flap. A great cloud of dust rises from them. Then she moves on.
Heads swivel and eyes follow a finger pointing skyward.
Locked together, talons to talons, African fish eagles plummet toward earth in their mating dance, twirling in passionate grip with each other, taut bodies wheeling faster and faster towards earth, picking up suicidal speed. Spiraling, spiraling, feather tip to feather tip, wind streaming through their feathers.
The eagles break off a second before hitting the ground and swoop up to roost in trees opposite each other. They scream back and forth, flinging their heads over their shoulders. The female’s voice is lower, counter-point to the male’s shriek.
One of the guides shakes his head. “I have never seen that before.”
Like the bald eagles in North America, African fish eagles have chestnut bodies, long yellow beaks, yellow feet, pure white heads, white tails and white chests, although their bibs are larger.
They have the same habits – they mate for life and build huge stick nests in trees, nests twelve feet wide and ten feet deep. They dwell in the same habitats – rivers, lakes, creeks, lagoons, estuaries, sea coasts and man-made reservoirs. Both carry fish caught near the water’s surface in their grasping talons, carry the fish headfirst for lesser wind resistance, one claw behind the other, surfing, riding a fish through waves of air.
Holding to their tree with fierce feet, the eagles continue to scream at each other, perhaps in excitement from their mating twirl, or perhaps because they are dizzy. Eagles have somewhat the same structure in their inner ears as humans, including the looping canals for balance. Ah, that instinct, the one that will sweep you off your feet, twirl you around, make you dizzy, breathless, and, for the moment, drop you down totally in love.
Chobe River, 2012
Dear Madame Elephant:
There is a hole in the space between us, filled with thrown dust. You stare down your nose with a don’t-mess-with-me look, but I am describing things in my language, not yours. Yours is a language of thunder, trombones, and a low, rumbling growl. Your breasts are full; your child hides behind you. We have come knockata-knockata noisy around the corner in a vehicle now halted before you. How quickly we became silent and supplicant, waiting with immobile slightly bowed heads, as you sample the scent of our intentions. We are watchers watching each other. Your eyes are deep brown pools. Your benevolence is the most important thing to us. We hope you will bestow it upon us. Dear Madame Elephant, what would you tell us in our language, if you could. Or did you already tell us: your forbearance louder than our beating hearts, louder than words.
A Thankful Human
As the Earth turns on its axis, everything attached to it turns with it, a lovely effect of the force we call gravity. Without gravity, we’d fly off into space in less than a heartbeat.
The earth’s rotation has another beneficial effect: instead of the atmosphere circulating only between the poles (high pressure areas) and the equator (a low pressure area), circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curled paths. This deflection is called the Coriolis effect, named after the French mathematician Gaspard Gustave de Coriolis (1792-1843) who studied the transfer of energy in rotating systems like waterwheels.
Because of this atmospheric circulation, it’s also believed that water goes down a sink in one direction in the Northern Hemisphere and in the opposite direction in the Southern Hemisphere. Coriolis’s deflection causes weather systems to rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere, so it seems somewhat obvious that a sink should drain in a similar manner.
However, cyclonic systems are often more than 600 miles in diameter and may exist for several days. By contrast, a typical sink is less than four feet in diameter and drains in a matter of seconds. On this scale, the Coriolis force is miniscule – and not really observable.
But enterprising hucksters never let the impossible get in the way of yet another tourist trap. In Nanyuki, Kenya, a little town located right on the equator, proof of the Coriolis effect exists. In the burnt shell of the Silverbeck Hotel, at the exact altitude of 6389 feet, (the sign says so), a small squarish plastic sink with a very small hole in the bottom of it rests on a pinkish bucket. The gullible group I’m with stands in the southern hemisphere. The demonstration goes like this: one of the demonstrators holds the empty sink and puts his finger in the hole to plug it. Water is slowly poured into the sink, the finger removed, and the sink is carefully set over the bucket. Matchsticks are added. The water, very slowly drains and the matchsticks barely move. Then the whole enterprise is moved about twenty feet away into the Northern Hemisphere. The sink is plugged, filled from the bucket and water in the sink is allowed to settle down. Then the sink is set down and once again, matchsticks are added to the water. The matchsticks rotate counterclockwise. Moved twenty feet into the Southern Hemisphere, the matchsticks rotate clockwise. After the demonstration we’re given the golden opportunity to purchase a certificate commemorating our witnessing of the Coriolis effect, so we can prove to our friends, who may never have a chance to visit the equator, that we saw one of the wonders of the world.
Alas, the truth always gets in the way of good stories. The secret for this deception is in the shape of the sink and a little choreography. For the first demonstration right at the equator, the water in the sink behaves as it should, with no discernible matchstick rotation in either direction. For the northern part of the demonstration, the pan was filled as the demonstrator faced the equator. He then turned to his left, walked around the bucket, turned to his left again, before he pulled the plug of his finger and added matchsticks. He’s just induced counter-clockwise rotation in a non-circular pan – because of drag, water will turn as the pan does. For the Southern hemisphere he repeated his actions, but turned to the right instead of left.
Clever, eh? But, no worries. Half the world believes that sinks drain differently in different hemispheres. It fooled Michael Palin, too, on a PBS show, no less. And it’s actually true that you can demonstrate the effect with draining water, but you need a kid’s pool, 41 degrees of separation and synced cameras, like these dudes did:
Vervet monkeys chatter to each other as they jump along the branches of a Sausage tree over my head. I look up. The monkeys peer down through the tree’s large, leathery leaves. Small bits of dead flowers rain down. Brown eyes in the middle of narrow black faces stare back at me.
They wouldn’t, would they?
Last night, without any aid from the monkeys, the tree dropped a bomb next to my tent. At two feet long, six inches in diameter, and weighing nine pounds, one of the fruits dangling deli-style from the Sausage tree made quite an impressive WHUMMP! when it hit the sand. I wonder about the motives of the potential bombardiers overhead.
Light-gray thin bodies dart from branch to branch. The monkeys stop and stare, stop and stare. The bombardiers look as if they wear black oxygen masks and gray flight coats with white ruffs.
More bits of flowers and leaves rain down.
Livingston camped beneath a Sausage Tree right before he discovered Victoria Falls. What if its fruit had bonked him in the head? Stanley might have searched in vain for the famous explorer and never uttered, “Livingston, I presume?”
And what would have happened if that relentless experimenter, Isaac Newton, had been beaned with a sausage fruit instead of an apple? Would we still have the theory of gravity?
I bet that we would. After recovering from a concussion, Newton would have gone right ahead and figured out his equations. After all, this was the guy who stabbed his eye with a needle just to see what would happen.
The Vervet monkeys tire of watching me and settle higher in the tree. Thanks to the restraint of my overhead companions, I’m able to continue on without incident.
Found mostly in seasonally arid areas, baobabs grow very slowly as they age, except for first years of its life, when a baobab grows relatively quickly. A tree planted in Kruger National Park in South Africa grew 65 feet tall with an eleven-foot diameter in just 38 years. In contrast, an older tree described by Livingstone in 1858 grew only two feet in circumference in 110 years. Despite their early exuberance, baobabs can be cultivated as bonsai trees.
Young baobabs have only single leaves per stem. Without their crooked branches and five-leafed stems, they are difficult to recognize. Kalahari Bushmen believe the trees appear fully-grown, planted upside down by the gods, with the tree’s roots in the air. They also believe spirits inhabit the baobab’s large, waxy-white flowers, and if anyone has the audacity to pick one, they will be eaten by a lion. The flowers open just before dark, produce copious amounts of nectar and last for only 24 hours. Their heavy, carrion-like scent attracts nocturnal insects and bats, such as the Epaulleted fruit bat. The Kalahari Bushmen are right: the smell of a freshly-picked baobab flower behind your ear would make you bait for lions drawn to the carrion scent.
Older baobabs have a tendency to rot out their heartwood, but completely heal around the hollowed trunk. Rats and reptiles frequently invade them and African honeybees often establish hives in crevices of a baobab. Native to central and southern Africa the bees are actually a subspecies of the Western honeybee. A single sting from an African bee is no more venomous than a single European or American bee sting, but African honeybees respond more quickly when disturbed and send out three to four times as many workers in response to a threat. They also pursue an intruder for a greater distance from the hive – thus their reputation as “killer” bees.”
Physically unable to break open a beehive, the Honeyguide has developed a symbiotic relationship with humans, letting another species take the risk of being swarmed. A Honeyguide indicates the presence of a hive by continuously dive-bombing nearby, all the while uttering monotonous, squirrel-like chirps. Alerted by the Honeyguide, intrepid Kalahari Bushmen pound pegs into the soft bark of baobabs to climb the tree, lull the bees with smoke and obtain a sweet reward for taking that risk. Bushmen always leave honey for the birds, for if they should fail to do so, the Honeyguide will one day lead them to a lion, instead of a hive.
“Pachycaul” is a scientific term used to describe a variety of thick-stemmed plants with few branches. “Pachy” is Greek for “large” and “caul” is Latin for “trunk.” Pachyderm is a term for describing large, thick-skinned animals such as elephants. In times of drought, elephants strip the bark of the baobab and eat the spongy wood underneath, estimated to contain 40-70% water – which classifies the baobab as the world’s largest succulent. An individual baobab can store up to 32,000 gallons of water. When pachyderms meet pachycauls, it is the baobab that suffers. Sometimes, during these times of drought, elephants will completely gird a tree, leaving it standing as if on its own pedestal, and yet the baobab will still survive.
Weighted with water, baobabs barely move in the wind. Even a mild frost will kill a baobab, so they are never found at elevations over 3,000 feet. The tree is also sensitive to both flood and extended periods of drought. In Madagascar, a sugar mill diverted water onto land containing baobabs, which subsequently stood in water year-round. The trees began to rot and topple over until the land was drained and the remaining 313 baobabs upon it were declared part of a conservancy area. A highway constructed near the Nomslang Baobab in South Africa brought thousands of visitors to marvel at its size. Unfortunately, their feet trampled the earth beneath it into hardpan, making the ground impervious to rainwater and the famous baobab died. Baobabs melt into a huge, fibrous mass within a few months after their death, leaving behind mounds of stinking pulp and a pit filled with a rotting taproot. Soft spots around dead baobabs also indicate locations of its root system, which may radiate just below the surface for 300 to 1300 feet.
Some species of plants and trees emit chemical signals when under attack. I wonder if the baobab talks to its long-lived kin as it dies. Baobabs live up to two thousand years, 730,000 revolutions of daylight and darkness. Perhaps its chemical whisper is Patience, perhaps it is Eternity, perhaps it is Dream.
The most comprehensive book ever written about baobabs is The Baobabs: Pachycauls of Africa, Madagascar & Australia, Gerald Wilkins and Pat Lowe
In 1998, the Disney Corporation opened the Animal Kingdom Park in Florida. It is, in essence, a 500-acre zoo, containing 1,700 animals representing 250 species, from Abdim’s storks to African zebras. In the center of the park is a 145-foot-tall, 50-foot-wide sculpture of a baobab, representing the Tree of Life from the Disney film, The Lion King. Much larger than any known baobab, the sculpture is molded around a refitted oil platform. Its trunk is carved with 325 animals and contains a theater with 430 seats. Fixed to its branches are 103,000 leaves dyed five shades of green, made of kynar, a flexible fluoropolymer resin.
Eight species of living baobabs exist: six in the dry deciduous forests of Madagascar, one in Australia and one which grows in West, East and Southern Africa. Baobabs on the Arabian Peninsula are the result of human settlements. All baobabs are deciduous. Nude limbs, entangled as a root system, seem to search for moisture from the sky. Kalahari Bushmen believe the trees appear fully-grown, planted upside down by the gods, with the tree’s roots in the air. They also believe spirits inhabit the baobab’s large, waxy-white flowers, and if anyone has the audacity to pick one, they will be eaten by a lion.
Hollow baobabs have a long history of creative uses by humans. During World War II, a baobab in Namibia was fitted with a toilet. The toilet is still there, but the tree has grown around the door, which no longer opens. On the lower Zambezi River, the Kayila Lodge has an operational toilet tree, used more for photo opportunities than necessity. And on a private farm in Sunland, South Africa, an enormous baobab contains a wine cellar and bar, complete with draft beer, a dartboard, stools, and a wooden bench along the wall. This tree is possibly the oldest baobab in existence – it has been radiocarbon-dated to the end of the Stone Age, around six thousand years ago.
In Kasane, Botswana, a baobab was used as women’s prison in the early twentieth century. Incarceration with potential rat and reptile cellmates might make any criminal think twice. Although that baobab died in 1967, an offshoot now grows next to the remains of the jail. Throughout Africa, hollow baobabs have served various purposes – as hiding places during tribal warfare, as shops, storage shelters, barns, chapels, burial sites, post offices, even a bus stop.
Almost every part of the baobab is edible. Fresh leaves are eaten as spinach and condiments. The shoots from germinating seeds taste like asparagus. Bulbs from its roots make porridge. Fluid extracted from the bark of the baobab is used to dilute milk. The ash from a burnt tree is a good substitute for salt. Pulp and seeds of its fruit contain potassium acid tartrate as well as citric acid, an effective substitute for cream of tartar, and resulting in the Afrikaans name “Kremetartboom.” Early settlers also used fruit pulp in place of yeast and added baobab leaves to speed up the fermentation process in winemaking. The fruit pulp has the highest known concentration of Vitamin C. It makes a slightly acidic, but refreshing drink when mixed with water. Baobab seeds have the same protein value as domestic nuts and can also be roasted and ground into a substitute for coffee.
The baobab is often called “the Monkey-bread tree,” because baboons and monkeys eagerly consume its fruits. Nearly all four-legged browsers eat the baobab’s fallen leaves and flowers. The flowers open just before dark, produce copious amounts of nectar and last for only 24 hours. Their heavy, carrion-like scent attracts nocturnal insects and bats, such as Peter’s Epaulleted Fruit Bat. In times of drought, elephants strip the bark of the baobab and eat the spongy wood underneath, estimated to contain 40-70% water – classifying the baobab as the world’s largest succulent. An individual baobab can store up to 32,000 gallons of water and weigh 266,880 pounds – or one hundred and twenty-one tons. A bull elephant weighs up to 16,000 pounds or seven tons. If you stacked elephants one upon the other, it would take seventeen or eighteen elephants to equal the weight (if not the mass) of the water stored in a large baobab.
The name baobab derives from North African Arabic, bu-hibab, “fruit of many seeds.” Within life spans that reach six thousand years, the baobab nourishes countless species, takes in tons of carbon dioxide and releases equal amounts of oxygen. Used and re-used, a baobab cycles and recycles, measures seasons by dropping its leaves, measures centuries by the blur of life beneath its limbs, unaware of that strange human notion of time.
