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.


Axolotl

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.


Blobfish



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.
Taxonomy
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.
Appearance
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.
Status
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.

Christmas Tree Worm


  The worm is aptly named; both its common and Latin names refer to the two chromatically hued spiral structures, the most common feature seen by divers. Actually, the multicolored spirals are merely the worm's highly derived respiratory structures.
S. giganteus is similar to most tube-building polychaetes. It has a tubular, segmented body lined with chaeta, small appendages that aid the worm's mobility. Because it does not move outside its tube, this worm does not have any specialized appendages for movement or swimming.
The worms's most distinct features are two "crowns" shaped like Christmas-trees. These are highly modified prostomial palps, which are specialized mouth appendages. Each spiral is composed of feather-like tentacles called radioles, which are heavily ciliated and allow any prey trapped in them to be transported to the worm's mouth. While they are primarily feeding structures, S. giganteus also uses its radioles for respiration; hence, the structures commonly are called "gills."
One major difference between Christmas-tree worms and the closely related sabellida fan worms is that the latter do not have any specialized body structures to plug their tube holes when they withdraw into them. S. giganteus, like other members of its family, possess a modified radiole, usually called the operculum, that it uses to secure its hole when withdrawn into its tube.
As an annelid, S. giganteus possesses a complete digestive system and has a well-developed closed circulatory system. Like other annelids, these worms possess well-developed nervous systems with a central brain and many supporting ganglia, including pedal ganglia, unique to the Polychaeta. Like other polychaetes, S. giganteus excrete fully developed nephridia. When they reproduce, they simply shed their gametes straight into the water where the eggs (and spermatozoa) become part of the zooplankton to be carried by the currents.

Angora rabbit

 

The Angora rabbit is a variety of domestic rabbit bred for its long, soft hair. The Angora is one of the oldest types of domestic rabbit, originating in Ankara, Turkey, along with the Angora cat and Angora goat. The rabbits were popular pets with French royalty in the mid 1700s, and spread to other parts of Europe by the end of the century. They first appeared in the United States in the early 1900s. They are bred largely for their long wool, which may be removed by shearing or plucking (gently pulling loose wool).
There are many individual breeds of Angora rabbits, four of which are ARBA recognized. Such breeds include, French, German, Giant, English, Satin, Chinese, Swiss, Finnish, to name a few.

Leafy seadragons




  Named after the dragons of Chinese mythology, Leafy seadragons (Phycodurus eques) resemble a piece of drifting seaweed as they float in the seaweed-filled water. The Leafy seadragon, with green, orange and gold hues along its body, is covered with leaf-like appendages, making it remarkably camouflaged. Only the fluttering of tiny fins or the moving of an independently swiveling eye, reveals its presence.
 
  Like the seahorse, the male seadragon carries as many as 150-200 eggs. After being deposited by the female, the eggs are carried in the honeycomb-shaped area (known as the brood patch) under the male's tail for approximately eight weeks. Seadragons have no teeth or stomach and feed exclusively on mysidopsis shrimp. Known as "Australian seahorses" in Australia, they are found in calm, cold water that is approximately 50-54° F (10-12° C). Leafy seadragons have been protected by the South Australian government since 1982.

Purple Frog

PURPLE FROG



  Nasikabatrachus sahyadrensis is a frog species belonging to the family Sooglossidae. It can be found in the Western Ghats in India. Common names for this species are Purple FrogIndian Purple FrogPignose Frog or Doughnut Frog. It was discovered by S.D. Bijuand F. Bossyut in October 2003 and was found to be unique for the geographic region.
With its closest relatives in the Seychelles, the Nasikabatrachus is thought to have evolved separately for millennia. Its discovery also adds to the evidence that Madagascar and the Seychelles separated from the Indian landmass sometime well after the breakup of Gondwanalandhad started. Owing to its ancient lineage, the purple frog has also been called "the coelacanth of frogs".

The body of ''Nasikabatrachus sahyadrensis'' is shaped similarly to that of most [frogs], but is somewhat rounded compared to other more dorsoventrally-flattened frogs. Its arms and legs splay out in the standard [Anura|anuran] body form. Compared to other frogs, ''N. sahyadrensis'' has a small head and an unusual pointed snout. Adults are typically dark [[purple]] in color. The [Holotype|specimen] with which the species was originally described was seven centimeters long from the tip of the [snout] to the tip of the [[urostyle]]. Also, its cry sounds more like one from a [chicken].
The species was discovered in the Idukki district of Kerala by S.D. Biju from the Tropical Botanic Garden and Research Institute in Palode, India and Franky Bossuyt from the Vrije Universiteit Brussel (Free University of Brussels). However it was well known to the local people before and several earlier specimens had been ignored.
Earlier thought to be restricted to the Western Ghats south of the Palghat gap, new records have extended its known range further north of the gap.

The frog spends most of the year underground, surfacing only for about two weeks, during the monsoon, for purposes of mating. The frog's reclusive lifestyle is what caused the species to escape earlier notice by biologists.
Unlike many other burrowing species of frogs that emerge and feed above the ground, this species has been found to forage underground feeding mainly on termites using their tongue and a special buccal groove. They show inguinal amplexus when mating afloat in temporary rainwater pools.

The scientific name derives from the Sanskrit word nasika (nose) referring to the pointed snout, batrachus Greek for frog, and Sahyadri as the local name of the mountain range where it was found - the Western Ghats.
The frog is a living fossil and was initially assigned to a new family of its own, Nasikabatrachidae, but has been more recently assigned to the family Sooglossidae which is found on the Seychelles islands.
Being a member of the family Sooglossidae, the species' origins lie in close consort with the Seychelles islands where the family was previously solely known from. The origin of the disjunct distribution goes back to about 100 million years ago, during which time India, the Seychelles and Madagascar formed a single landmass which split due to continental drift.

THE WOLF-TRAP ANGLERFISH


THE WOLF-TRAP ANGLERFISH
 There are 2 basic kinds of Wolftrap Anglers, each with their own genus. They are Lasiognathus andThaumatichthys. One thing they share, and which gives them their name, is their extraordinary mouths. The lower jaw is quite short, with short teeth. This is all relative of course. Anglerfish are famed for their massive maws and these lower jaws are by no means short, it's just that the upper jaw is utterly shocking. It's significantly longer and wider, with these kind of "lips" that can close down around the lower jaw. They aren't lips, they're called premaxillaries. There's bone in there, and the edges are lined with long, curved or even hooked teeth. It's akin to our very own Venus Flytrap... Venus Wolftrap, perhaps. It's like their upper jaw has it's own downward facing jaws. Ick.

Lasiognathus have an esca at the end of a long illicium (lure at the end of a fishing rod). The esca is bioluminescent and even has hooks on it, leading to all sorts of theories as to how it's used, including ideas of it being cast forward and used to impale prey. Nice idea, but it might not be necessary - a bait with some nearby jaws may well be enough to capture the small, bony fish that make up their diet. Speaking of which, there are 5 known species of Lasiognathus, the longest of which is 15.7 centimetres, the smallest is half that. They have been found in various locations scattered across the Atlantic and Pacific Oceans at depths of about 4,000 metres (13,100 feet). All this is the female, no male has yet been discovered.

View from the bottom and top.
Thaumatichthys are a little different. Here, the illicium is upside own and backwards so that the esca hangs down from the roof of the mouth like a chandelier. There are also little bumps in there which act as taste buds. Oh dear. Little animals hoping for a cosy, fireside resting place will realise their mistake when those upper jaw jaws close around them. Thaumatichthys are unique among deep sea anglers in that they are bottom feeders, which I guess is why they are so flattened in shape. They also seem to be omnivorous, even eating plant matter. There are three species so far, the biggest found was 36.5 cm long and found 3,600 m (11,800 feet) down. Another was just under a foot long and the third is known from just one 6 cm specimen. These are found at depths between 1,000 and 2,000 m (3,300-6,600 ft) and they are all from tropical waters worldwide. The biggest male discovered is 45 millimetres long and is armed with not much more than great, big olfactory organs for a great, big sense of smell. It's not known whether he's parasitic to the female, but it doesn't look unlikely.

Barreleye

All species have large, telescoping eyes which dominate and protrude from the skull, but are enclosed within a large transparent dome of soft tissue.[4] These eyes generally gaze upwards, but can also be directed forwards.[5] The opisthoproctid eye has a large lens and a retina with an exceptionally high complement of rod cells and a high density of rhodopsin (the "visual purple" pigment); there are no cone cells. To better serve their vision, barreleyes have large, dome-shaped transparent heads; this presumably allows the eyes to collect even more incident light and likely protects the sensitive eyes from the nematocyst (stinging cells) of the siphonophores from which it is believed the Barreleye steals food. It may also serve as an accessory lens (modulated by intrinsic or peripheral muscles), or refracts light with an index very close to seawater. A recent study disclosed that Dolichopteryx longipes is the only vertebrate known to use a mirror (as well as a lens) in its eyes for focusing images.[6]
The toothless mouth is small and terminal, ending in a pointed snout. As in related families (e.g. Argentinidae), there is an epibranchial or crumenal organ present behind the fourth gill arch. This organ—analogous to the gizzard—consists of a small diverticulum (pouch) wherein the gill rakers insert and interdigitate for the purpose of grinding up ingested material. The living body of most species is a dark brown covered in large, silvery imbricate scales; but these are absent in Dolichopteryx, leaving the body itself a transparent white. In all species a variable number of dark melanophores colour the muzzle, ventral surface, and midline.

Tiburonia granrojo



Tiburonia granrojo, is a jellyfish of the family Ulmaridae discovered in 2003, and the only member of its genus yet identified. It was discovered by MBARI(Monterey Bay Aquarium Research Institute), and the lead marine biologist on the crew was Dr. George I. Matsumoto, Ph.D. Its genus name is Tiburonia because the ROV (Remotely Operated Vehicle) the crew were using was called Tiburon, meaning "shark" in Spanish. Its species name was originally to be called "Big Ugly", but an unknown party denied it and renamed it granrojo, meaning "big red" in Spanish. It is one of the largest sea jellies and unusual in a number of ways.
   Tiburonia granrojo live at ocean depths of between 600 and 1500 metres and have been found across the Pacific Ocean in the Sea of Cortez, Monterey Bay, Hawaii and Japan. They can grow up to 75cm in diameter[1] , according to the California Academy of Sciences, and have thick fleshy oral arms in place of the long tentacles found in most jellies. The entire jellyfish is deep red in color.[2]
