Pink Fairy Armadillo (Chlamyphorus truncates)

There are twenty extant species of armadillos–new world placental mammals covered with armored plates. The smallest of these armored creatures is the Pink Fairy Armadillo (Chlamyphorus truncates) which is only 9-12 centimeters in total length (about 4 or 5 inches).  The diminutive creature weighs slightly more than 100 grams when mature and inhabits the central drylands of Argentina.  It has multiple hard ring-like plates of delicate pink which it can close into a box form for protection (although its first defensive strategy is to dig into the ground).  The animal has tiny eyes and a torpedo-like head for pushing into the sand. The portions of the Pink Fairy Armadillo not covered with plates are covered in dense white fur. Like the golden mole of Namibia, the pink fairy armadillo is a sand swimmer:  the little animal agitates the fine, dry sand with its powerful claws and literally swims through the turbulence with its hard bullet shaped body.  The armadillos are also like the golden mole in that they can lower their metabolism to levels unheard of among other placental mammals.  However armadillos are not closely related to the golden mole—or indeed to any other placental mammals other than fellow Xenarthra (the sloths, armadillos, and anteaters).  South America spent a long portion of geological time as an island and the mammals there had a long time to develop on their own.  It is still not known whether Xenarthrans like the Pink Fairy Armadillo are truly Eutherians or whether they are the descendants of the ancestors of the Eutherians (sorry: the language of cladistics does not lend itself to eloquent explanations and all of the names sound like they come from a far-away planet—for example “Xenarthrans”).

I would like to tell you more about the Pink Fairy Armadillo, but I am unable to do so.  Since it lives underground, the animal is rarely seen in the wild.  It is even more unusual in captivity where it does not long survive the shocks and stresses of zoo living (additionally it seems unable to live on anything other than local invertebrates). This is unfortunate as it is believed that the Pink Fairy Armadillo is struggling in the wild.  It is presumed to be declining in numbers–a victim to habitat loss from human activity.  I used wiggle words like “believed” and “presumed” because nobody really has any idea about the actual populations of Pink Fairy Armadillos.

In the absence of real information here is a little gallery of Pink Fairy Armadillo artwork.  Enjoy these pictures, it is profoundly unlikely you will ever see a real Pink Fairy Armadillo in the real world (which is sad because I find them curiously endearing). I particularly like the cartoon of the Pink Fairy Armadillo dreaming of transcendence into a mythical fairy being.

The Giant Ground Pangolin of Africa (Manis gigantea)

The pangolin is one of the most unusual and fascinating mammals of Africa and Asia.  The magnificent creatures have unique strengths and gifts, but because of unhappy superstition (and gustatory whim) they are facing an uncertain future.

Despite a superficial resemblance to anteaters and armadillos, pangolins are most closely related to the carnivora family (cats, dogs, weasels, seals, and so forth).  The relationship is not unduly close: pangolins make up their own order of which there is one extant family (Manidae) and one genus (Manis). There are eight species of pangolins, each of which is sheathed in a virtually impregnable suit of keratin scales which act as armor.  All pangolins can roll into pinecone-like balls leaving only the razor sharp edges of their scales to confront predators. Not only does the pangolin possess armor, every adult has formidable claws with which to burrow into termite mounds and root insects out of bark (or to utilize as a defensive weapon) as well as a gland capable of spraying a foul acid onto would-be predators.  Additionally, while they may lack the uniquely acute mental equipment of the gnome-like echidna, pangolins are considered quite clever.  They are gifted at avoiding traps and seem to evince real creativity in seeking out and consuming bugs, particularly ants and termites, which compromise a large portion of their diets. Many pangolins are adept climbers, capable of taking to the trees both to hunt and to escape danger. Tree pangolins even have prehensile tails with which they can dangle from branches. Other pangolins are great burrowers. In fact  in Chinese myth they travel everywhere in a great underground network and their Cantonese name “Chun-shua-cap” means the creature that bores through the mountain.

Alas, Chinese legends are not all so kind to chun-shua-cap. Although pangolins are gifted with impregnable armor, mighty claws, keen intelligence, skunk-like acid spray, dexterity, as well as great digging, swimming, and hiding skills, they have a relentless enemy more implacable than any lion or plague. South China’s burgeoning middle class hungers for them with insatiable rapacity. Ancient custom dictates that ingesting their scales somehow magically aids nursing mothers (which, aside from the placebo effect, is a complete fallacy). Additionally pangolins are a prestige food for the newly moneyed millions who do not know what to do with wealth and, like the Very Reverend William Buckland, desire to consume everything that lives. China has eaten its own pangolins and is quickly driving the remaining pangolins of South East Asia, Indonesia, and South Asia to extinction. Additionally, as Africa’s troubled nations become vassals to Chinese cash and commodities-grubbing (and as Africa’s tin-pot dictators abase themselves before China’s moral equivocation) the pangolin trade is starting to gobble-up Africa’s pangolins, which were already facing pressure from the bush-meat trade and deforestation. Pangolins reproduce slowly.  Because of their diet and lifestyle they can’t be farmed. If China’s ever-growing demand for them is not curbed they will vanish from Earth forever.

Chinese police, customs officers, and wildlife officials (and their counterparts in neighboring nations) have begun to strike back at the illegal trade in pangolins and other endangered species.  But as long as Chinese high officialdom turns a (very) blind eye on consumption, the problem will linger.  Come on China! You are always clamoring to be regarded as a truly great world power.  I will acknowledge you as such as soon as you rescue the world’s pangolins (and maybe the rhinos, bears, elephants, and tigers while you are at it). Everyone has these wacky superstitions which get in the way of real greatness (just look at America’s checkered history) but saving the pangolins should be possible for a nation whose government possesses such absolute authority. Or will China’s rise merely present a list of needless extinctions and tacky plastic cities as its heritage to posterity?

Since I have already written so many mammal posts I am creating a new blog category for mammals (I will leave out human concerns to concentrate on zoologic overviews of other species, but please remember that technically we too are mammals and all of the posts on this and every website could fall under this category).  To make way for the mammals I deleted the “celebrity” topic for good (I had hoped to make fun of our queasy fascination with lackwit celebrities–but other than an one sighting of the disquieting Richard Simmons, I had nothing). Begone vile celebrities! The age of the mammals has dawned.

The Giant Otter, Pteronura brasiliensis

I already have plenty of posts about goats, pigs, wombats, hyraxes, and bizarre intelligent monotremes with which to populate this category, but to kick the topic off properly I am writing today about the alpha-predator of the Amazon.  This mammal is the king of the Mustelidae (also known as the weasel family) and, if you have ever seen a lightning fast stoat hunting a rabbit, or smelled a skunk, or watched a badger drive off a bear, or witnessed a wolverine tear apart a moose, you will know that the weasel family is not joking around. [ed: what? When did you see any of this?] The largest mustelid is a particularly magnificent creature—the giant otter (Pteronura brasiliensis) which lives throughout the Amazon basin and Pantanal.  The giant otter is a long animal and males are up to six feet (2 meters in length) and weigh up to 100 pounds (45 kilograms).  Much longer males measuring nearly 8 feet in length were once reported but it is believed that extensive hunting may have eradicated all of the really giant giant otters.

Giant otters are tremendously accomplished fishers living largely on cichlids, characins (such as piranha), and catfish, but, as an apex predator they are opportunists who supplement their diet with snakes, crabs, turtles, and caimans.  Although the otters are diurnal predators who hunt at daytime using their large acute eyes to find their prey, their hearing is also excellent and they possess extremely sensitive vibrissae (whiskers) to gauge the faintest water current.  Like other mustelids, giant otters have fast metabolisms and they eat about 10% of their body weight per day.  Their adaptations to aquatic life include webbed feet, ears and nostrils which clamp shut, powerful tails for swimming, and incredibly dense fur.  As with their cousins the sea otters, this valuable fur proved to be their undoing. During the nineteenth and early twentieth century they were hunted to the very threshold of extinction by furriers (and by fishermen who regard them as a clever nuisance). Their numbers still remain low today: only 2,000-5,000 giant otters are estimated to live in the wild.

Orphaned Giant Otter Cubs

Giant otters form family groups around a mated pair.  Older offspring from years past stay with this pair and help out rearing the young cubs before venturing off on their own. They travel widely through the inundated forest during flood seasons and spend the rest of the year based around a fishing camp which they build beside a lake or a choice stretch of river.  These camps consist of large multiple entrance home dens built under and around tree roots as well as several secondary locations (along with communal latrine areas).  The otters might also alter river beaches to be more to their liking by removing vegetation.  The fur of the giant otter is usually brown, red, or fawn and the otter’s bib is marked with cream and white stipples.  These are for identification purposes: otters “persiscope” up out of the water to get a better view of each other and to learn whom they are meeting.  Giant Otters are also famous for their complicated (and loud) vocalizations.

Although the adult giant otter has no natural predators, young otters must look out for caimans, jaguars, and anacondas. Additionally the giant otters compete for prey with these creatures as well as with river dolphins, large predatory fish, and large turtles.  The otters are always on the lookout for dangerous stingrays and electric eels.  None of these natural threats, however, are particularly significant compared with the threat from habitat loss, logging, mining, and industrial pollution.

Some of the native humans indigenous to the great river basins believed the otters were river spirits who had, once taught valuable lessons to the first humans.  Other native peoples (particularly fishing people) held that the otters were worthless nuisances to be killed or run off whenever sighted.  Such sightings however grow increasingly rare as the giant otter, the longest mustelid, vanishes forever away from all but the wildest places in the rainforest.
