Blobfish
The blobfish (Psychrolutes marcidus) is a fish that inhabits the deep waters off the coasts of Australia and Tasmania. Due to the inaccessibility of its habitat, it is rarely seen by humans.
Blobfish are found at depths where the pressure is several dozens of times higher than at sea level, which would likely make gas bladders inefficient. To remain buoyant, the flesh of the blobfish is primarily a gelatinous mass with a density slightly less than water; this allows the fish to float above the sea floor without expending energy on swimming. The relative lack of muscle is not a disadvantage as it primarily swallows edible matter that floats by in front it.
Pygmy Marmoset
The Pygmy Marmoset (Callithrix (Cebuella) pygmaea) is a monkey native to the rainforest canopies of western Brazil, southeastern Colombia, eastern Ecuador, and eastern Peru. It is one of the smallest primates, with its body length ranging from 14-16 cm (excluding the 15-20 cm tail) and the smallest monkey. Males weigh around 140 g (5 ounces), and females only 120 g (4.2 ounces).
TDespite its name, the Pygmy Marmoset is somewhat different from the typical marmosets classified in genus Callithrix. As such, it is accorded its own subgenus, which was formerly recognized as its own genus, Cebuella.
TThe Pygmy Marmoset has a tawny coat, and a ringed tail that can be as long as its body. Their claws are specially adapted for climbing trees, a trait unique to the species. They are omnivorous, feeding on fruit, leaves, insects, and sometimes even small reptiles. Much of their diet, however, comes from tapping trees for sap. Up to two-thirds of their time is spent gouging tree bark to reach the gummy sap. The Pygmy Marmoset has specialized incisors for gouging holes in bark. Unfortunately, because of its small size, and its swift movements, it is very hard to observe in the wild.
TIn captivity, the Pygmy Marmoset can live up to 11 years.
Tarsier
Tarsiers are prosimian primates of the genus Tarsius, a monotypic genus in the family Tarsiidae, which is itself the lone extant family within the infraorder Tarsiiformes. The phylogenetic position of extant tarsiers within the order Primates has been debated for much of the past century, and tarsiers have alternately been classified with strepsirrhine primates in the suborder Prosimii, or as the sister group to the simians in the infraorder Haplorrhini. Analysis of SINE insertions, a type of macromutation to the DNA, is argued to offer very persuasive evidence for the monophyly of Haplorrhini, where other lines of evidence, such as DNA sequence data, had remained ambiguous. Thus, some systematists argue that the debate is conclusively settled in favor of a monophyletic Haplorrhini.
Tarsiers have enormous eyes and long feet. Their feet have extremely elongated tarsus bones, which is how they got their name. They are primarily insectivorous, and catch insects by jumping at them. They are also known to prey on birds and snakes. As they jump from tree to tree, tarsiers can catch even birds in motion. Gestation takes about six months, and tarsiers give birth to single offspring. All tarsier species are nocturnal in their habits, but like many nocturnal organisms some individuals may show more or less activity during the daytime. Unlike many nocturnal animals, however, tarsiers lack a light-reflecting area (tapetum lucidum) of the eye. They also have a fovea, atypical for nocturnal animals.
Alpaca
The Alpaca (Vicugna pacos) is a domesticated species of South American camelid developed from the wild alpacas. It resembles a sheep in appearance, but is larger and has a long erect neck as well as coming in many colors, whereas sheep are generally bred to be white and black.
Alpacas are kept in herds that graze on the level heights of the Andes of Ecuador, southern Peru, northern Bolivia, and northern Chile at an altitude of 3500 to 5000 meters above sea-level, throughout the year.
Alpacas are considerably smaller than llamas, and unlike them are not used as beasts of burden but are valued only for their fiber. Alpacas only have fleece fibers, not woolen fibers, used for making knitted and woven items much as sheeps wool is. These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles and ponchos in South America, and sweaters, socks and coats in other parts of the world. The fiber comes in more than 52 natural colors as classified in Peru, 12 as classified in Australia and 22 as classified in America.
Aye-aye
The Aye-aye (Daubentonia madagascariensis) is a strepsirrhine native to Madagascar that combines rodent-like teeth with a long, thin middle finger to fill the same ecological niche as a woodpecker. It is the world's largest nocturnal primate, and is characterized by its unique method of finding food; it taps on trees to find grubs, then gnaws holes in the wood and inserts its elongated middle finger to pull the grubs out.
Daubentonia is the only genus in the family Daubentoniidae and infraorder Chiromyiformes. The Aye-aye is the only extant member of the genus (although it is currently an endangered species); a second species (Daubentonia robusta) was exterminated over the last few centuries.
Axolotl
The Axolotl (or ajolote) (Ambystoma mexicanum) is the best-known of the Mexican neotenic mole salamanders belonging to the Tiger Salamander complex. Larvae of this species fail to undergo metamorphosis, so the adults remain aquatic and gilled. The species originates from the lake underlying Mexico City. Axolotls are used extensively in scientific research due to their ability to regenerate most body parts, ease of breeding, and large embryos. They are commonly kept as pets in the United States, Great Britain, Australia, Japan (where they are sold under the name Wooper Rooper, and other countries.
Axolotls should not be confused with waterdogs, the larval stage of the closely related Tiger Salamanders (Ambystoma tigrinum and Ambystoma mavortium), which is widespread in much of North America which also occasionally become neotenic, nor with mudpuppies (Necturus spp.), fully aquatic salamanders which are unrelated to the axolotl but which bear a superficial resemblance.
Porphyria is an inherited genetic condition that results in the buildup of porphyrins (organic compounds that have various functions in the body, including the production of red blood cells). Porphyria attacks the entire body, particularly the liver, and can cause all manner of mental health issues. Sufferers of cutaneous porphyria have to limit their exposure to sunlight, which would cause their skin to swell and blister. It is thought that the appearance of people with porphyria may have helped give rise to legends of vampires and werewolves.
