The Most Useful Appendage Ever Evolved

Posted on March 4, 2012 by Cheryl Merrill

Morula plucks a branch from one of her favorite snacks, a bush-willow. She holds the stem in her teeth, wraps her trunk from right to left around the branch, and sheers off leaves, top-to-bottom with a single swipe. She drops the branch and transfers the leaves from the curl of her trunk into her mouth.

Morula is right-trunked, as I am right-handed, preferring to grab and wrap from the right. Thembi is also right-trunked, but Jabu’s a lefty.

One of the ways to determine an elephant’s dominant tendencies is to inspect the underside of its trunk for green stains on either the right side or the left. But before you do this, make sure you know the elephant and, more importantly, the elephant knows you.

Morula peels and discards branch after branch. Shredded bushes mark her path. She pauses next to a candle-pod acacia, easily recognizable by its upright seedpods. It reminds me of a giant leafy candelabrum, holding a hundred or more candles in ruffled tiers. Sharp curved thorns protect each pod. Morula strips the acacia of a branch, then puts it in her mouth and eats it, thorns, pods and all.

She sidles close to Doug and curls her trunk against her forehead.

“Those round bumps on her forehead might be an old skin infection,” Doug tells me, “but we really don’t know.”

A light breeze feathers the hair in her ears as she stands slightly sideways and nods the tipof her trunk in a tiny Hello. . . Ribbed muscles cross the underside of her trunk. Bristles stick out like the legs of a giant centipede.

There is no other living creature on this planet that has a trunk. If elephants were already extinct, which brave paleontologist would go out on a limb and reconstruct the trunk just from evidence of bony nostrils high on the skull? Who could imagine a nose dangling close to the ground where scents abound? A nose with the ability to pick up a single straw, rip a tree out by its roots, bench-press 600 pounds and untie your shoelaces without you ever noticing?

“Stand here,” Doug commands me.

I obey, my back to an elephant lineup.

With a little guidance from Doug, Thembi gently places the tip of her trunk on top of my head. It feels like a big beanbag up there, but one that’s warm, wiggly, drooling and breathing.

As Thembi rubs nose slime into my hair, Doug places Jabu’s trunk tip on my right shoulder and then Morula’s on my left.

Jabu has trouble keeping his trunk balanced on such a narrow ledge. He constantly fidgets and pokes my cheek with his bristles. Morula’s trunk drapes over my shoulder like a slack hose with a dripping nozzle. Her runny nose continuously drains to clear out inhaled dust – the common condition of all elephant trunks.

When I look down and to the left, I have a close-up view of the two “fingers” on her trunk. Her top finger is more pointed than the one on the bottom. The shape of it reminds me of a hooded cobra. But perhaps that’s because I think of Morula’s trunk as thinner and “snakier” than Jabu’s spectacular snout.

Which is getting heavier by the moment. With the peripheral vision in my right eye, I see two nostrils dotted with grains of moist sand, nostrils more flesh-colored than gray. Each opening is nearly as wide as the “O” of my mouth.

All three trunk tips, I can attest, are not just sheer weights. They sniff, snorf, squirm, wiggle, inhale and exhale. They create an atmosphere of elephant breath around my head.

Doug lowers my camera and pronounces, “Allll-right.”

The weights disappear. For a few steps I am oddly light, as if walking on the surface of the moon.

There is an elsewhere, somewhere, but it’s not a place I want to be right now.

Heart

Posted on February 14, 2012November 15, 2014 by Cheryl Merrill

I’m reposting this piece in honor of the new year. It occurred very early in my blog:

Heart shapes can be found in nature, if you’re lucky enough to spy one. There’s a heart on Jabu’s trunk, a ridge of skin that feels like fine shoe leather. One of his wrinkles pierces the lower third of this heart shape, from left to right, straight as an arrow. His real heart hangs between his breastbone and ribs, a little to the left, just like mine does. But instead of having a heart with a single point, an elephant’s heart has two points at its apex – so it’s the wrinkled outline of a human heart that Jabu carries on his trunk.

The length of Jabu’s real heart is about twenty-two inches, its width eighteen. His heart weighs around forty-four pounds, almost the same as a medium-sized dog. Still, it’s less than 1% of his body weight, a common proportion among large mammals and among humans. My heart also weighs less than 1% of my body weight: about ten ounces.

The human heart is approximately five inches long, three-and-a-half inches wide and shaped like a pulsing cone. It is the only muscle in my body that acts on its own – my heartbeat doesn’t need any messages from my brain. The cells in my heart tissue involuntarily constrict, all together, all at once, over and over, a soft perpetual-motion machine. Rip my heart from my body, chop it into pieces, immerse the pieces in a saline solution, and then give them a small jolt of electricity. The remnants of my cardiac muscle will contract . . . contract . . . contract – all on their own, sometimes for hours.

It’s designed to be strong, my heart.

In mammals, birds, and reptiles the heart has the same basic pump-like design, a design that has worked through eons – even cold-blooded dinosaurs had hearts. A day or two after fertilization, embryos develop a pinpoint that pales, then brightens, pales, then brightens, the beginnings of a tiny pump practicing emptying, filling, emptying, refilling. An old, old pattern. The master timepiece.

There are four chambers in my heart: two auricles (“little ears”) and two ventricles (“little bellies”) – named by anatomists for the external parts of the body they resemble. Spent, dark-red blood is collected in the right auricle, then dropped into the right ventricle, which constricts and pumps it out to the lungs to pick up oxygen. Bright red again, full of oxygen, blood circulates back to the left auricle and from there drops into the left ventricle. In the next twitch blood is delivered to every corner of my body.

The “little ears,” the auricles, make very little sound as they drain blood into the lower chambers of my heart, a distance of an inch or so. It’s the ventricles, the “little bellies,” that boom as each contraction forces open heart valves and blood gushes up the aorta under pressure. Lupp DUPP. Lupp DUPP. Lupp DUPP. One beat smaller, one beat larger, flush after flush.

My right ventricle has walls thin as paper – it delivers blood only as far as the lungs. If I could hold it up to the light I could see right through it. The left side of my heart is the heavyweight lifter, pumping blood all the way to my toes, moving 150,000 tons of blood in my lifetime.

Jabu’s great artery, the aorta, takes off from the left ventricle of his heart, the same as mine does. Named in the Middle Ages, aorta means, “to heave.” It’s an artery more flexible and sturdier than any manmade pipe. Jabu’s left ventricle pumps a continuous stream of blood up and out of his heart into the aorta, which then drops down into his chest and down each leg, where it branches and branches and branches all the way to his toes. Each arterial branch has less space than the artery it came from, but the sum of their volume is always greater than their mother artery. The blood moves, but more and more slowly through smaller and smaller pipes, trickling into all corners of Jabu’s body, trickling through capillaries one cell thick.

Blood’s trip back to the heart is made through veins. Millions of tiny venules drain into thousands of small veins, thousands drain to hundreds, hundreds to the one that empties back into the heart. Veins are even more elastic than arteries, can hold variable quantities of blood, and serve as a reservoir for all that moving liquid. At any one moment, 65% of my blood is contained in my veins. It’s an ancient blueprint, this branching, this heartbeat, this coming and going, a blueprint brought to life in even the tiniest of creatures.

Blood has to be literally hoisted from Jabu’s toes. Squeezed along by muscles wrapped around veins, pushed by valves in the veins, and sucked upward by the huge action of breathing, blood finally arrives in the vena cava, where it drops into the heart. Jabu has two vena cavae, possibly because of the large amounts of blood that need to be moved. The blood vessels of an African elephant reach lengths of twelve feet, a huge network of life.

Jabu’s body contains 120 gallons of blood, enough to fill an aquarium six feet long, two feet wide and two feet deep. At one-and-a-half gallons, my puny amount of blood would barely fill a birdbath.

Blood is the body’s only liquid organ, five times denser than water. It takes food and water in, removes waste and byproducts to the disposal areas of the body, the kidneys, lungs, and skin. Blood irrigates all tissue, both feeds and cleanses. It leaves the heart at one mile per hour and returns, laden with waste, at about half that speed. Construction materials move along highways of blood, demolished materials return. Blood is 20% solids and 80% water, carrying products of digestion, products made by the body, foreign intruders, the dust of stars, even cobalt from the original ocean of the earth where both of us, human and elephant, began our journeys.

We each have roughly one billion heartbeats for our lives. Mouse, hummingbird, elephant, human, all the same. Like us, elephants suffer cardiovascular disease, die of heart attacks and strokes.

Cardiac arrest: when the heart shudders and stops, when the light in the eyes flickers, fades and snuffs.

And when the heart quits beating, its resonance

Lupp DUPP Lupp DUPP Lupp DUPP

is gone. The gurgle of digestion, all the silky, sturdy, slapping noises, the blood rush, gone. The symphony of the body is finished.

For those of us left, that silence is almost too much to bear.

An excerpt from my book:

Under a sun-bleached sky that is no longer blue, dry coughing barks from black-backed jackals lope in from our left . . . Wraack, wraack, wraack. . . Black-backs are scavengers, more aggressive than other types of jackals, and occupy the same ecological niche in Africa as coyotes do in North America. They are bold enough to steal meat within the reach of a lion’s paw – although their main diet consists of insects, lizards, snakes, rodents, birds and ripe fruit. Unlike coyotes, black-backed jackals do not howl.

Up ahead of us 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.

Veins in ear b&w — The veins in Morula's ear

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.

Whooosh, thwack . . . Whooosh, thwack . . . Whooosh, thwack . . .

Jabu sidles up to Morula to investigate the thorn branch in her mouth. Sandi intercepts him and reaches into her bag of treats.

“Jabu, be nice to Morula,” she says.

Jabu holds out his trunk, cups his treat and puts a handful of pellets into his mouth. While he’s busy, Sandi reaches back into her bag and transfers treats to the inside curl of Morula’s trunk. Morula fans her ears, her perfect maps of Africa, and continues munching on her thorn branch. She finishes the branch before eating her treats.

An excerpt from my book:

There is nothing like him on earth. His head alone is more immense than an entire gorilla. Jabu is one hundred times larger than I am. His trunk is larger than I am. A single leg is larger than I am. He fills my entire range of vision.

He reaches out with his trunk and rests it on the ground in front of my boots. The tip of it lifts, opens, inhales my scent.

Do you recognize her, Jabu?” Sandi asks him. Gently he swings his trunk to tap lightly against Sandi’s shoulder bag.

What’s in there?” I ask.

Sandi shows me a little mound of pellets cupped in her hand. “Pressed alfalfa, wheat bran, salt, ground corn and sunflower hulls.” Elephant candy, immediately vacuumed into Jabu’s trunk and transferred to his mouth.

Jabu turns his head toward me. And You?

I hold out empty hands. His trunk hovers over them for less than a second and then drops down to rest near my feet. As I run my fingers along his warm tusk he snorts out a huge exhale, CHUFFFFFffffffff.

The Elephants Who Accepted Me as Part of Their Herd

Posted on January 3, 2012April 28, 2012 by Cheryl Merrill

An excerpt from my book:

Jabu, Morula and Thembi live in Botswana’s Okavango Delta. I don’t need radio collars or binoculars or even 4-wheel drive vehicles to study them. They are companions, who allow me to walk alongside them, close as an eyelash. Adopted as orphans from culling operations by Doug and Sandi Groves, they spend their days as most wild elephants do: strolling and eating. But they are also willing ambassadors between the elephant world and the human world.

Walk with me. Stroll with three unfettered and unfenced elephants in a world where the thin-skinned sky is a bare reminder that the earth is covered with air, where clouds stampede as if chased by lions – a world without asphalt, without cell phones, without that strange human notion of time.

I hope you enjoy and follow this blog.
