Otter Love


It was clear to me, on watching Diane McTurk interact with the two otters (giant Amazon and Neotropical river) she had raised, that her affection for them runs every bit as deep as mine for my beloved Chet Baker. In raising and releasing these animals, Diane runs a gamut of emotions. Giant Amazon otters are territorial, and though they are endlessly tolerant of family members, they will sometimes kill interlopers. In fact, a lone male giant otter had come to Karanambu and killed at least one of her orphans. Having raised quite a few young songbirds, I know how tough it can be to raise a young thing up, only to see it killed just as it's learning how to live.

We spent a few minutes watching Diane with her otters just before departing Karanambu. Her face glowed with affection as she spoke lovingly to them. They seemed to adore her equally. After all, she was their mom!I noticed that she took more liberties with the Neotropical river otter than the giant otter. In this picture, you can see why the Neotropical river otter (the closest to Diane) is Lontra longicauda (long-tail). Diane sneaks a caress of the giant otter while he's occupied.After my minor perforation, I wasn't scratching nobody under the chin, but I had a hard time keeping my hands off the unbelievably silky fur of the otters. Don't try this unless you're the otter's mama. 

Oh, how I missed my Bacon, doubtless stretched frog-legged on the bed at home in Ohio. I kind of missed my scorpion-free bed, too.Canis turdicauda, the Tennessee Turd-tail, at rest.

While we're on tails, look at the giant otter's amazing appendage. His Latin generic name is Pteronura, or "feather tail," referring to its flattened aspect. The central "vane" of vertebrae only adds to the tail's feather-like appearance. It's much like a caiman's tail, and it makes a fine propeller in water.

The river otter wanted to be in the boat to take the sun with his giant pal.

Longicauda helped himself. What does he do with all that tail?And was soon routed by Mr. Giant Bossy Boots (looking very much like a sea lion here) who wanted the boat to himself.

Both otters then repaired to shore, where they rolled over and over in the warm sand. Their fur dried amazingly fast. A very dense, silky underfur traps air and prevents water from ever reaching their skin.

In just a few minutes, the sand and the hot Guyanan sun turned this slick little river otter into a living teddy bear.
Is it any wonder that so many of us love otters?   And their tiny otter junk?Throughout all our interactions, the giant Amazon otter never ceased to vocalize. To imagine how he sounded, squinch your vocal cords all up and imitate a crying baby, pushing the sound through your nose. Waaaa! Weeee! Weeeeyyyyyyewwwww! Weh!!

I want, I want, I want!

If he doesn't favor a baby elephant seal here, I'm a monkey's uncle.

Giant Amazon Otter: Hands, Lips, Eyes, and Fur

We're still lolling by the Rupununi River in Guyana, South America, ogling a giant otter. What gorgeous webbed feet and hands he had! I wanted to touch them.
In this photo, you can see two of the distinguishing features of giant vs. river otter: the luscious pink lips of the giant otter, and the creamy markings on its throat. The giant otter's whitish throat bib is uniquely shaped in each individual, a wonderful mark for researchers wishing to study family groups. Sure beats having to catch and mark them!

The Neotropical river otter, below, has a diffuse grayish-white throat and less bodacious lips. I also noted that the giant otter has googly eyes, whose whites are often evident, and the Neotropical river otter does not. Pity. Googly eyes are Web magic.The Neotropical river otter got out of the water, while the giant otter stayed in, chewing on half a fish.

It was beginning to sink in on me that I was looking at two of the rarest mammals in the Amazon, probably rarer even than the giant anteater. Oddly, population estimates for giant otter (I couldn't get them for the Neotropical river otter) run somewhere below 5,000 individuals, just as they do for the anteater. I don't know how "they" arrive at that number, but it's the one I have. Giant otters have been horrifically persecuted for their satiny fur-the shortest otter fur going. Wikipedia states that between 1959 and 1969 Amazonian Brazil alone accounted for 1,000 to 3,000 giant otter pelts annually. Well, that ought to clean them out pretty quickly. One pelt could be worth a year's wages to a hunter. And for what? Furry collars and cuffs for ladies' coats? The species was so thoroughly decimated that the Brazilian population dropped to just 12 in 1971. It's a marvel that any remain. (Don't touch me right now; my eyes are glowing red).

One thing that contributes to the otter's plight is its insatiable curiosity. Like a Science Chimp, giant otters just have to know. And so they bob up and periscope their long elegant necks and holler and squeal and goggle and stare at people in boats, sometimes even approaching them. Bad idea. There's a precedent for such behavior on the part of vanishing animals. Carolina parakeets would circle around a fallen flockmate, allowing shooters to take the whole flock.

There's some evidence, though, that giant otters as a species are finally beginning to grasp that human beings are not to be trusted, but still they all too easily fall prey to poachers and kidnappers who wish to keep them as pets. That's another bad idea, since giant otters are highly social, and depend completely on their family groups for contact, affection, and survival in the wild. Diane McTurk knows that better than anyone.

And so, though the Neotropical river otter is a solitary animal in the wild, this one (right) serves a mighty purpose in keeping the squally baby giant otter (left) company day in and day out. I've never seen a wild animal so attached both to its animal friend and its human caretakers. The giant otter squealed, caterwauled and complained constantly, trying to follow us as we departed by boat. It just seemed to want to be part of a larger group--any group. It's hard-wired to be this way, since giant otters live in family groups of 5-9 in the wild, consisting of a mated pair and perhaps two years' worth of offspring. The first time he squealed and swam after our boat, I almost wept, and then I realized that that is why he has a human caretaker and an otter friend--to keep him out of trouble until he can be socialized with other giant otters. Giant otter rehabilitation makes songbird rehab look like a walk in the park. My hat is off to Diane and her helpers.

Sorry about the weekend giant otter cliffhanger. A girl has to take some time off. But it is bad form to leave you wanting more ottritude for three whole days.

Next: Zick gets PERFORATED.

What? Are you surprised?

Giant Amazon Otter!

I thought I had seen the Amazon's rarest mammal in the giant anteater, but there were more amazements yet to come. Karanambu Ranch is famed as a rehabilitation/rescue site for orphaned giant otter cubs, in the singular person of Diane McTurk. Diane is one of those people whom you meet, look at and instantly wish you could multiply somehow, to spread all that knowledge and caring around for awhile longer. There's no better way to learn an animal than to live with it, and Diane has been mama to multitudes of orphaned and kidnapped giant otter cubs. Through them, she's come to know the animal as no one else on the planet does. Upon arriving at Karanambu, we were taken down to the banks of the Rupununi to meet two of Diane's charges, who were swimming freely in the river under the eye of an Amerindian attendant .

I was confused upon seeing my first semi-wild otter in South America. But for some eye and nose issues, it looked very much like our North American river otter (Lutra canadensis). If this was a giant otter, it must be a baby. I stared and stared, trying to reconcile what I was seeing with what I had been expecting to see. It was a gorgeous little thing.

As became abundantly clear in just a few moments, this was not a giant Amazon otter, but a Neotropical river otter, Lontra longicaudus. A life mammal, to be sure, and endangered (CITES Appendix 1). It was out of habitat here in this silty, slow-moving river, having been brought to Diane as a purported giant otter from an unknown locale. Neotropical river otters inhabit clearer, faster-flowing streams than do giant Amazonian otters. Nevertheless, Diane accepted it and raised it, and it has given vital companionship to the star of the show and central focus of Diane's life work.

First peek of the giant Amazon otter, Pteronura b. brasiliensis:

Hello!Oh my! What nice pink lips you have!At this point I had been away from home for several days and was jonesing heavily for Chet Baker. This otter's googly eyes and floppy lips did something for me. If you've always had a Thing for Otters, as I have, a Boston terrier is the next best thing. And unlike otters, they're perfectly legal to keep as pets!

Nah, nothing otterlike about this dog. Couple that pining for The Bacon with the fact that I never thought I'd ever lay eyes on a giant Amazon otter, and I am in a full Science Chimp swoon.
