weird and unique animal species

In this world there is alot of unique and weird animal that we don't know, here is some of the have been found and discovered. Do you know that there is more species that  we not discovered yet.


The axolotl (pronounced /ˈæksəlɒtəl/), Ambystoma mexicanum, is a neotenic mole salamander 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 Lake Texcoco underlying Mexico City and is also called ajolote (which is also the common name for the Mexican Mole Lizard). 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 (sold under the name wooper looper (ウーパールーパー Ūpā Rūpā?)) 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 are widespread in much of North America and also occasionally become neotenic, nor with mudpuppies(Necturus spp.), fully-aquatic salamanders which are not closely related to the axolotl but bear a superficial resemblance.
As of 2010, wild axolotls are near extinction due to urbanization in Mexico City and polluted waters. Nonnative fish such as African tilapia and Asian carp have also recently been introduced to the waters. These new fish have been eating the axolotls' young, as well as its primary source of food.The axolotl is currently on the International Union for Conservation of Nature's annual Red List of threatened species.


The blobfish (Psychrolutes marcidus) is a deep sea fish of the family Psychrolutidae. Inhabiting the deep waters off the coasts of mainland Australia and Tasmania, it is rarely seen by humans.
Blobfish live at depths where the pressure is several dozen times higher than at sea level, which would likely make gas bladders inefficient for maintaining buoyancy. Instead, 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. Its relative lack of muscle is not a disadvantage as it primarily swallows edible matter that floats by in front of it.
Blobfish can be caught by bottom trawling with nets as bycatch. Such trawling in the waters off Australia may threaten the blobfish in what may be its only habitat.
The Blobfish is currently facing extinction due to deep-sea fishing.

Glass Frog (  Glassfrogs )

Glass frog (or Glassfrogs) is the common name for the  of the amphibian family Centrolenidae (order Anura). While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent. The internal viscera, including the heartliver, and gastrointestinal tract are visible through thistranslucent skin, hence the common name.

Dumbo octopuses (Grimpoteuthis )

  The octopuses of the genus Grimpoteuthis are also known as Dumbo octopuses from the ear-like fins protruding from the top of their head-like bodies, resembling the ears of Walt Disney's flying elephant. They are bathyal creatures, living at extreme depths of 3000–4000 meters, with some living up to 7000 meters below sea level, which is the deepest of any octopus species to be found. They are some of the rarest of the Octopoda species. They can flush the transparent layer of their skin at will, and are pelagic animals, as with all other cirrate octopuses. The largest Dumbo octopus ever recorded was 6 feet in length and weighed 13 pounds, although the normal size for the various species is thought to be smaller.
They hover above the sea floor, searching for worms, bivalves, pelagic copepods, and other crustaceans for food. The Dumbo octopus is strange in the way it consumes food in that it swallows its prey whole, which differs from any other kind of octopus. They move by pulsing their arms, shooting water through their funnel, by waving their ear-like fins, or any combination thereof. Males and females differ in their size and sucker patterns. Dissected females have yielded eggs during different stages of development, which has led to the conclusion that females lay eggs consistently, with no distinct breeding season. Male Dumbo octopuses possess an enlarged segment on one of their arms, similar to the hectocotylus arm of other cephalopods. It is likely that this modified arm transfers masses of spermatophores into the female during copulation, as occurs in other cephalopods.

Proboscis monkey (Nasalis larvatus)


The proboscis monkey (Nasalis larvatus) or long-nosed monkey, known as the bekantan inMalay, is a reddish-brown arboreal Old World monkey that is endemic to the south-east Asianisland of Borneo. It belongs in the monotypic genus Nasalis, although the pig-tailed langur has traditionally also been included in this genus - a treatment still preferred by some.
The monkey also goes by the Malay name monyet belanda ("Dutch monkey"), or even orang belanda ("Dutchman"), as Indonesians remarked that the Dutch colonisers often had a similarly large belly and nose.
Proboscis monkeys belong to the Colobinae subfamily of the Old World monkeys. There are two subspecies:
  • Nasalis larvatus larvatus (Wurmb, 1787), which occupies the whole range of the species;
  • Nasalis larvatus ssp. orientalis (Chasen, 1940), restricted to north-east Kalimantan.
However, the difference between the subspecies is small, and not all authorities recognise N. l. orientalis.
A distinctive trait of this monkey is the male's large protruding nose, from which it takes its name. The big nose is thought to be used to attract females and is a characteristic of the males, reaching up to 7 inches in length. The females also have big noses compared to other monkey species, but not as big as the males. Besides attracting mates, the nose serves as a resonating chamber, amplifying their warning calls. When the animal becomes agitated its nose swells with blood, making warning calls louder and more intense.
Proboscis monkeys exhibit a high degree of sexual dimorphism. Males are much larger than females, weighing up to 24 kg (53 lb) and reaching 72 cm (28 in) in length, with a tail of up to 75 cm in length. Females are up to 60 cm long, weighing up to 12 kg (26 lb). This large difference is greater than in any other primate.
The adult Proboscis monkey is mainly reddish-brown, with grayish limbs. According to Burnie (2001), young Proboscis monkeys have a blue face, blackish fur and a relatively normal sized nose at birth. As they grow older, fur coloration changes and the nose grows. Adult males have a large and fleshy nose which overhangs its mouth, but the female does not have a large nose in comparison to the male.
Ecology and Habitat
The Proboscis monkey is endemic to Borneo's low elevation mangrove forests, swamps, and lowland riparian forests. One of the largest populations is found in the Danau Sentarum National Park. It lives in small groups of 10 to 32 animals. Group membership is very flexible, and animals are known to move from group to group quite often.
The Proboscis monkey's lifestyle is both arboreal and amphibious, with its mangrove swamp and riverine environment containing forest, dry land, shallow water allowing wading, and deep water requiring swimming. Like other similar monkeys, the Proboscis monkey climbs well. It is also a proficient swimmer, often swimming from island to island, and has been picked up by fishing boats in open ocean a mile from shore. While wading, the monkey uses an upright posture, with the females carrying infants on their hip. Troops have been filmed continuing to walk upright, in single file, along forest trails when they emerge on land, the only non-human mammal, with the exception of gibbons and giant pangolins, known to use this form of locomotion for any length of time.
Proboscis monkeys usually live in a harem which comprises one adult male, several females, and their offspring, but sometimes the male and females move between social group. The Proboscis monkey is mostly arboreal, but sometimes the animals migrate downriver into the mangrove forest to feed.
The monkey has a large belly, a result of its diet. Its digestive system is divided into compartments, with bacteria that digest cellulose and neutralize toxins from certain leaves. This lets the monkey eat leaves and remain in the forest canopy. Their stomach contents weigh about a quarter of their whole body weight. The diet consists mainly of seeds, leaves, fruits, and mangrove shoots.
The Proboscis monkey is assessed as Endangered in the IUCN Red List of Threatened Species and listed in Appendix I of CITES. Its total population has decreased by more than 50% in the 36–40 years to 2008 due to ongoing habitat loss and hunting in some areas. The population is fragmented: the largest remaining populations are found in Kalimantan; there are far fewer in Sarawak, Brunei and Sabah. The Proboscis monkey is protected by law in all regions of Borneo. In Malaysia, it is protected by a number of laws including the Wildlife Protection Act (federal law), the Wildlife Protection Ordinance 1998 (Chapter 26) and Wildlife Conservation Enactment 1997 (Sabah state law).
The Proboscis monkey is known to occur in 16 protected areas: Danau Sentarum National Park, Gunung Palung National Park, Kendawangan Nature Reserve, Kutai National Park, Lesan Protection Forest, Muara Kaman Nature Reserve, Mandor Reserve and Tanjung Puting National Park in Indonesia; Bako National Park, Gunung Pueh Forest Reserve, Kabili-Sepilok Forest Reserve, Klias National Park,Kulamba Wildlife Reserve, Lower Kinabatangan Wildlife Sanctuary, Sungei Samunsam Wildlife Sanctuary and Ulu Segama Reserve in Malaysia.
