Falkland Islands Wolf..

The Falkland Islands Wolf (Dusicyon australis), also known as the Warrah and occasionally as the Falkland Islands Dog, Falkland Islands Fox or Antarctic Wolf, was the only native land mammal of the Falkland Islands. This endemic canid became extinct in 1876 (on West Falkland island), the first known canid to have gone extinct in historical times. It was the only modern species in the genus Dusicyon. Original research supposed that the most closely related genus is Lycalopex, including the Culpeo and his domestic forms which itself has been introduced to the Falkland Islands in modern times. But 2009 research conducted by a scientific team directed by Graham J. Slater, a post-doctoral researcher at the University of California, Los Angeles, confirmed that the Falkland Island wolf's closest living relative is actually the Manned Wolf - an unusually long-legged, fox-like South American caned, which it separated from about 6.7 million years ago. It was known from both West and East Falkland, but it is unknown if the varieties were much differentiated.
The fur of the Falkland Islands Wolf had a tawny colour. The tip of the tail was white. The diet is unknown. Due to the absence of native rodents on the Falklands, its diet probably consisted of ground-nesting birds such as geese and penguins, grubs and insects, as well as seashore scavenging. It was sometimes said to have dwelt in burrows.

Sumatran Rhinoceros...

The Sumatran Rhinoceros (Dicerorhinus sumatrensis) is a member of the family Rhinocerotidae and one of five extant rhinoceroses. It is the only extant species of the genus Dicerorhinus. It is the smallest rhinoceros, standing about 120–145 centimeters (3.9–4.8 ft) high at the shoulder, with a body length of 250 centimeters (98 in) and weight of 500–800 kilograms (1100–1760 lb). Like the African species, it has two horns; the larger is the nasal horn, typically 15–25 centimeters (6–10 in), while the other horn is typically a stub. A coat of reddish-brown hair covers most of the Sumatran Rhino's body.

Double-banded Argus...

Unmistakable large pheasant. Male (120 cm) has enormously elongated secondary feathers and central tail feathers. The wing feathers are boldly decorated with large eye-spots. Plumage generally rusty brown with intricate buff and black spots and patterns; underparts darker rufous. Female (60 cm) has shorter tail and wing feathers, is darker rufous, and lacks the male's eye-spots. Both sexes have blue bare skin of head and neck and a short dark crest. Males clear dancing rings on the forest floor, removing all leaves, seedlings, and stones. They call from these dancing grounds in the morning, and give a visual display to visiting females by raising and fanning the tail and wings, somewhat like the display of a peacock. Birds roost in trees at night, and sometimes rest in and even call from trees in the day.

Lion Tamarins.

Lion tamarins have a mane derived from long hairs on the top of the head, cheeks and throat. The golden lion tamarin's color is predominantly golden with occasional orange, brown or black coloration on the tail and forepaws. It weighs about 0.5 kg (1.1 lb) and averages about 25 cm (10") in head/body length, not counting the tail.
The golden lion tamarin prefers primary lowland tropical forest from sea level to 1000 m (3300'). Golden lion tamarins are omnivorous, feeding on fruits, gum, nectar, insects, and small vertebrates. The golden lion tamarin is diurnal and predominantly arboreal. It is usually found at heights of 3 - 10 m (10 - 30') above the forest floor. It sleeps there at night in tangled vegetation or, more often, in a hole in a tree, such as an abandoned woodpecker nest.

SeaGull Bird...

Gulls (often informally called seagulls or Seahawks) are birds in the family Lerida. They are most closely related to the terns (family Steroidal) and only distantly related to auks, skimmers, and more distantly to the waders. Until recently[vague], most gulls were placed in the genus Lars, but this arrangement is now known to be polyphyletic, leading to the resurrection of several genera.
Gulls are typically medium to large birds, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls, stout, longish bills, and webbed feet. Gull species range in size from the Little Gull, at 120 g (4.2 oz) and 29 cm (11.5 inches), to the Great Black-backed Gull, at 1.75 kg (3.8 lbs) and 76 cm (30 inches).

Black Tern...

Adult are 25 cm (9.75 in) long, with a wing span 61 cm (24 in), and weigh 62 g (2.2 oz). They have short dark legs and a short, weak-looking black bill, measuring 27-28 mm, nearly as long as the head. The bill is long, slender, and looks slightly decurved. They have a dark grey back, with a white forehead, black head, neck (occasionally suffused with gray in the adult) and belly, black or blackish-brown cap (which unites in color with the ear coverts, forming an almost complete hood), and a light brownish-grey, 'square' tail. The face is white. There is a big dark triangular patch in front of the eye, and a brandish white collar in juveniles. There are grayish-brown smudges on the sides of the white breast, a downwards extension of the plumage of the upperparts. These marks vary in size and are not conspicuous. In non-breeding plumage, most of the black, apart from the cap, is replaced by grey. The plumage of the upperparts is drab, with pale feather-edgings. The rump is brownish-gray.


The walrus is a large flippered marine mammal with a discontinuous circumpolar distribution in the Arctic Ocean and sub-Arctic seas of the Northern Hemisphere. The walrus is the only living species in the Odobenidae family and Odobenus genus. It is subdivided into three subspecies the Atlantic Walrus found in the Atlantic Ocean, the Pacific Walrus found in the Pacific Ocean, and O. rosaries captive, found in the Laptev Sea.
The walrus is immediately recognized by its prominent tusks, whiskers and great bulk. Adult Pacific males can weigh up to 2,000 kilograms (4,400 lb) and, among pennies, are exceeded in size only by the two species of elephant seals. It resides primarily in shallow oceanic shelf habitat, spending a significant proportion of its life on sea ice in pursuit of its preferred diet of benthic bivalve mollusks. It is a relatively long-lived, social animal and is considered a keystone species in Arctic marine ecosystems.
The walrus has played a prominent role in the cultures of many indigenous Arctic peoples, who have hunted the walrus for its meat, fat, skin, tusks and bone. In the 19th and early 20th centuries, the walrus was the object of heavy commercial exploitation for blubber and ivory and its numbers declined rapidly. Its global population has since rebounded, though the Atlantic and Laptev populations remain fragmented and at historically depressed levels.

Danger in Green....

The black mamba (D. polytheism) is the longest venomous snake in Africa, with a potent neurotic venom that attacks the nervous system, and Cardiod toxins which attack the heart; the bite is often fatal to humans without access to proper first aid and subsequent ant venom treatment, because it shuts down the lungs and heart. Prior to the availability of antivenin, envenoms by members of this genus carried a high fatality rate. However, with ant venom being much more available today, fatalities have become much rarer.
The black mamba is not named for the color of its body (which is usually a shade of Grey or charcoal), but for the highly pigmented interior of its mouth, which it will display to the predator in hopes it will leave it alone. Many people believe that the black mamba will actually chase and attack humans. This is a myth, and is probably fueled by the great speed with which this species can move — although the black mamba uses this speed to escape from threats rather than for hunting. Humans are actually their predators, rather than their prey. For that reason, mambas generally avoid contact with humans. However, if a mamba feels threatened or trapped, it may defend itself fiercely, and it has the ability to attack repeatedly.

Anacondas live in South America, east of the Andes, mainly in the Amazon and Orinoco River basins, and in the Guianas. Their habitat is marshes, brushes, and swamps. They are never found far away from water. The swamps are their favorite spots. When kept out of the water, an anaconda's body becomes infested with ticks.
The anaconda gives birth to live young. The gestation period is 6 months. A female can have up to 20-40 babies and sometimes as many as 100. The young are usually 2 feet long. A couple hours after they are born, the young can swim, hunt and care for themselves. After mating, the anaconda grows longer but slower.
Snakes have a special jaw attachment that lets them swallow large animals whole. An anaconda's diet in the wild is: deer, wild pigs, birds, ocelot, other snakes, tapirs, sheep, dogs and large rodents like agouti, paca, and capybara . Its diet in the zoo is thawed rats once or twice a month. Anacondas act fast to catch their prey. When the anaconda strikes it will squeeze its prey to death, but it prefers to drown its victim. Although the anaconda is slow on land, it is quick and deadly in the water. The anaconda has been known to attack jaguars, and a 26 foot anaconda was reported to have killed a 6-and-a-half-foot caiman. A huge anaconda is capable of surviving for months and even years without food. One captive snake fasted for two years.

Whooping Crane.. really Tall

The Whooping Crane, the tallest North American bird, is an endangered species named for its whooping sound and call. Along with the Sand hill Crane; it is one of only two crane species found in North America. The whooping cranes lifespan is estimated to be 22 to 24 years in the wild. There is an estimate of only 250 left in the wild.
Adult whooping cranes are white with a red crown and a long, dark, pointed bill. Immature whooping cranes are pale brown. While in flight, their long necks are kept straight and their long dark legs trail behind. Adult whooping cranes' black wing tips are visible during flight
They stand nearly 1.5 meters (5 feet) with a wingspan of 2.3 meters (7.5 feet). Males weigh on average 7.0 kg (17 lb), while females weigh about 6.0 kg (14 lb).The only other very large, long-legged white birds in North America are: the Great Egret, which is over a foot shorter and one-seventh the weight of this crane; the Great White Heron, which is a morph of the Great Blue Heron in Florida; and the Wood Stork. All three other birds are at least 30% smaller than the whooping crane. Herons and storks are also quite different in structure from the crane.
