The Red Panda

The red panda (Ailurus fulgens) is also known in some areas as the shining cat. It is native to the eastern Himalayas and southwestern China. It is the sole member of its genus, Ailuirs. Its diet mainly consists of bamboo, but it is an omnivore and eats anything the woodlands provide. Its ability to eat bamboo rests with it's strong and sharp curved claws. A distant relative of the giant panda, red pandas have no more than 10,000 adults left in the world, though they are protected by several countries. Experts have blamed the population decline on the loss of natural habitat, and poaching. Like giant pandas, they also have false thumbs that are extensions of the wrist bone. These thumbs aid tremendously in gripping things. Red pandas are typically shy creatures that live solitary lives except around mating season. Females give birth to one to four cubs, usually in the spring and summer. Young pandas remain in their nests for about 90 days before venturing out on their own.

The red panda had been previously classified as a relative of the raccoon (for obvious visual reasons), but later this was found to be inaccurate. Though much smaller than their distant cousins, red pandas are indeed part of the panda family.

The Giant Coconut Crab

With the exalted title of the largest land-based arthropod in the world, it's a wonder that the giant coconut crab doesn't get more press than it does. These animals are generally nocturnal and live in many coastal and forest regions of Indo-Pacific islands.

They get their name from their ability to climb coconut palm trees, where they clip off the coconuts, return to the ground, peel of the coconut husks, and hammer the fruits open with rocks or their large claws. On some islands, the giant coconut crab is also known as the robber crab or palm thief because of its habit of taking shiny items.

Giant coconut crabs primarily eat nuts, seeds, and fleshy fruits such as coconuts. However, as omnivores, they will consume other items as well.

These large crabs have a body length of about 16 inches and a leg span of three feet. They can weigh up to nine pounds. There are even accounts of them growing to become more than six feet across and weighing up to 30 pounds. They can also live more than 30 years.

These crabs are unusual because they can't swim. Though they require water to survive, even smaller ones can drown in water. They have an organ called a branchiostegal lung, which can be described as a cross between gills and lungs. This lung allows the crab to take oxygen out of the air but also has to be kept moist to function. Because of the nature of this lung, one of the most likely times to see coconut crabs is during a rainstorm, as the moisture allows them to breathe more easily.

Though an adolescent has many predators, the only danger to a fully grown coconut crab is mankind—the crab is a delicacy as well as an aphrodisiac in Southeast Asia and the Pacific Islands. Female crabs are particularly in high demand if they have eggs that can be harvested.

Red Velvet Ant or "Cow Killer"

The Dasymutilla occidentalis are actually wasps. The females of the species are wingless and covered with red hair, giving it the appearance of an ant. The males of the species have wings, but cannot sting.

The red velvet ant is common in southwestern America and Mexico.

The wasp is also known as the cow killer, a misleading name because not many cows are stung, and it would be absurd to think that one bite would kill a cow. Instead, the name is a reference to the insect's severely painful sting, as if to say, "that hurt enough to kill a cow".

Sloth

Sure, we've all heard of sloths. But they are certainly very odd and unique creatures. There are multiple types of sloths:

  • Four types of three-toed sloths, or Bradypodidae
  • Eight varieties of Megalonychidae (including two two-toed and six extinct ground sloths)

Sloths are believed to have been around for about 60 million years and are distantly related to anteaters and armadillos. What most of them have in common is that they all mainly eat leaves, insects, small reptiles, and birds. Sloths have large slow-acting stomachs with multiple compartments. It can take a month or more for a sloth to digest something fully. These slow-acting stomachs in turn lead to a very slow digestive process and metabolism. Their metabolic rates are less than half of that of any other mammal its size, and they maintain a body temperature between 86 and 93 degrees (even lower when resting).

Sloths live in the rainforests of South and Central America, and despite their usually slow speed, they are not defenseless creatures. They will defend themselves if attacked, but it rarely comes to that because most sloths rarely visit the ground. Sloths also have a natural camouflage and move so slowly that it's difficult to spot them. Poachers pose little threat, as they have found that sloths usually do not fall from their tree perch even when shot.

In fact, the sloths' main threat is not predators but deforestation. Such a slow-moving mammal is put in harm's way if it has to relocate even a half a mile. Sloths' average ground speed is about six-and-a-half feet per minute!

Because sloths spend so much of their lifetimes hanging upside down, their hair grows the opposite direction of that of most mammals. The hair's reversed growth pattern helps protect their skin from the elements. Sloths even give birth hanging from trees. They go to the ground to defecate about once a week, burying their feces afterwards. The only oddity is that they use the same spot every time, which places them at risk. One theory is that they do so to nourish the tree they live in.

While today, sloths spend almost their entire lifetimes hanging from trees, in the past, many sloths were aquatic or ground-dwelling. Some ground-dwelling sloths could even grow to be the size of elephants. However, now these species of sloths are extinct.

Aye-Aye

The Daubentonia madagascariensis, commonly known as the aye-aye, is a type of Lemur only found on the island of Madagascar. The world's largest nocturnal primate, the aye-aye uses woodpecker-like strategies for food, tapping on the bark of a tree up to eight times per second to listen for insects inside. Then after chewing a hole in the wood, it digs out the grub or insect using its elongated middle finger. The aye-aye will spend 80 percent of its night foraging for food, traveling as far as 2.5 miles a night.

Due to its varied features, there has been an ongoing debate as to the classification of the aye-aye. The continually growing incisors leads some to believe it a rodent, and the aye-aye was originally classified as a mammal. Its re-classification as a primate has been just as widely debated.

Living primarily on the eastern coast and treeline of Madagascar, the aye-aye tends to live near the canopy of the forest, often as high as 700 meters above ground.

Though the males are considered to be social animals, it has been found that a females' territory will never overlap with another's.

The aye-aye's main threat is humans. Not only do the natives consider them to be nuisances, local legend says that the aye-aye is a symbol of death or harbinger of evil and should be killed on sight. Others believe that should an aye-aye point its narrow middle finger at you, you would be doomed to die. These superstitions are directly resulting in the species' decline.

Geoduck

The geoduck (pronounced "gooey duck") is a very, very large species of saltwater clam nNative to the northwest coast of North America and Southwestern Canada.

The shells can reach 15 to 20 centimeters in diameter, and the siphon, or neck, can grow as long as three-and-a-half feet. The average specimen weighs between one and three pounds, though people have reported finding geoducks weighing over 15 pounds.

They have been commercially harvested since 1989. Most sales go to Asia, where they are considered a delicacy and sell for about $30 a pound. The geoduck trade today is an $80-million-dollar-a-year US industry.

They also earn the title of one of the longest-living animals on the planet with a life expectancy of about 145 years (The oldest recorded at 160 years old).

The geoduck is the official mascot of The Evergreen State College located in Olympia, Washington. The school's Latin motto, Omina extares means "Let it all hang out." I wonder what they're referring to?

Giraffe Weevil

Native to Madagascar, the Trachelophorus giraffa gets its name from its jointed extended neck, which is similar to that of a giraffe. The majority of the body is black with distinctive red patterns covering the wings. The extended neck assists with nest-building and fighting. The giraffe weevil is the longest weevil in the world at around 2.5 cm.

Not much is known about the giraffe weevil, as it was only recently discovered, in 2008.

Tapir

Pronounced "ta-pier," the tapir appears to be a cross between a pig and an anteater. However, this mammal found in the jungles of South and Central America is actually more closely related to horses and rhinos.

Adult males can weigh up to 700 lbs. There are four different species of tapir, and, though the different species vary in color and fur, they all have oval white-tipped ears, rounded rumps, stubby tails, and as many as 44 teeth.

Their diet consists mainly of fruit, berries, and leaves though they have a tendency to eat soft foliage underwater if they live near a water source. They have been observed consuming upwards of 85 pounds of vegetation in a single day. Their size and remarkable speed keep them free from most predators. Despite this, and mainly due to loss of habitat, two of the four species of tapir are on the endangered species list.

Slender Loris

Native to India and Sri Lanka, the slender loris is the sole member of the genus Loris. A small nocturnal primate, this species can live in wet and dry forests, as well as lowland and highland areas.

Aptly named, the slender loris is about the size of a chipmunk and has long very thin legs. Their average lifespan is 12 to 15 years, and their movements are slow and meticulous so as not to alert any prey.

One of the loris's unusual habits is to rub their urine over their hands face and feet. This is thought to be a remedy for their foods of choice—toxic beetles and roaches. Their diet consists mainly of insects and vegetation.

Their main threat is humans as natives have always believed all parts of the primate have medicinal or magical powers. It is unknown how many survive in the world today. There are laws in India to protect the loris, but it is hard to gauge their numbers due to their nocturnal habits.

Monkfish

The monkfish, or headfish, is native to the Northeaster Atlantic Ocean and Mediterranean Ocean and is unusual because of its grotesque appearance.

Monkfish can grow upwards of three feet in length, and the largest recorded specimen was 219 lbs. They are in the genus Squatina, the angelshark family.

Although they are not widely consumed outside of Spain, the monkfish is endangered. This may be because they are caught as bycatch by trawlers (netted accidentally and later used as bait).

Sea Pig

Thriving on the deepest ocean floors, the sea pig behaves much like slugs do on land. They scavenge the ocean floor for any organic material, using their tube feet to move them along and their tentacles to push food into their mouth.

The sea pig is not an endangered species, but it is rare to see one due to the depths of the ocean at which they live.

Though they look as though they are a cross between a slug and a pig, sea pigs are Scotoplanes, or a genus of deep-ocean sea cucumbers.

Stick Bug (or Stick Insect)

The Phasmatodea (or Phasmida), is known around the world as a walking stick, stick bug, stick insect, or ghost insect.

They have evolved to have an exceptionally good natural camouflage that makes them difficult to spot (as you probably noticed from the first picture). In addition to their physical camouflage, walking sticks also have a tendency to sway, mimicking the movement of branches in the wind.

There are over 3000 known species of stick bugs around the world, but the insect is most abundant in tropical areas.

Giant Isopod

"Isopod" means crustacean, so this behemoth is actually related to shrimp and crabs.

First discovered in 1879 by French zoologist Alphonse Milne-Edwards, giant isopods were the first proof of life at the Azoic (deep ocean) level. They are of little interest to commercial fisheries as their numbers are too scarce to market, and specimens are often "scavenged beyond marketability" before they are recovered.

Giant isopods are also related and bear a resemblance to the pill bug or, as we know them around where I grew up, the roly-poly.

Mature adults can grow as long as 14 inches and weigh as much as 4 pounds. They are formidable scavengers of the deep sea. They live in areas over five hundred and fifty feet below the surface in pitch darkness; they consume the carcasses of dead whales, fish, and squid. Due to the lack of food at the depth they live in, they have adapted to long periods of famine. They are known to survive up to two months without any food.

Glass Frog

While, like many frogs, glass frogs are green, they get their name from their transparent abdominal sides. Their internal organs and gastrointestianl tract are visible through their skin.

First discovered in 1872, glass frogs were first placed ins the Hyella genus with tree frogs. It wasn't until 1951 that the family Centrolenidae was created. That family is now host to over 50 species of glass frogs. Found primarily along rivers and streams in Central and South America, glass frogs are small, between 1.2 and 3.0 inches in length.

Mata Mata

These freshwater turtles (Chelus fimbriatus) found in South America are distinguished by their large flattened head covered by many flaps of skin.

They can grow to a length of about 18-20 inches and a weight of around 30 pounds. Each foot has five webbed claws, which it uses, along with its natural camouflage, to catch fish and other food. The mata mata resembles a piece of wood of clump of leaves when it lies still in the water.

Mata mata turtles are common in the exotic pet trade but are quite expensive.
