Walrus

walrusDESCRIPTION: Walruses are very distinctive having alarge, robust, fusiform body that is usually reddish-brown in color. On theirhead region, walruses lack external ear flaps, have hundreds of short,vibrissae (whiskers), and both males and females possess large tusks. Likeother pinnipeds, the fore and hind limbs of a walrus are modified intoflippers. Although hair is present on the rest of the body, it is absent on theflippers. The foreflippers are short and square in shape with tiny claws on alldigits, and the hind flippers are triangular in shape with larger claws on thethree middle digits. On land, walruses are capable of rotating their hindflippers under their pelvic girdle to walk on all fours in a similar manner tosea lions.Adult males are slightly larger than femaleswith longer and stouter tusks.
SIZE:  The Pacific subspecies is larger than the Atlantic. Newborn calves are about 95-123 cm long.Male -  2.7-3.6 m,Female - 2.3-3.1 m
WEIGHT: Newborn claves weigh about 45-75 kg. Male: About 800-1,700 kg, Female:        About 400-1,250 kg
FUN FACTS:
  • Walruses spend about two-thirds oftheir lives in the water. Highly social in nature, huge herds of walruses haulout (leave the water to get on land) on sea ice to rest and bear their young.Most walruses live where the air temperature is about -15 to 5C (5 to 41F).
  • A thick layer of blubber insulates thewalrus. Blubber may be up to 15cm (6 in.)thick. During the winter, blubber may account for one-third of a walrus's totalbody mass. Blubber also streamlines the body and functions as an excess energyreserve.
  • To locate food, walruses use theirvibrissae (whiskers). A walrus has about 400-700 vibrissae on its snout.Vibrissae are attached to muscles and are supplied with blood and nerves. Awalrus moves its snout through bottom sediment to find food. Abrasion patternsof the tusks show that they are dragged through the sediment, but are not usedto dig up prey. Walruses may also take in mouthfuls of water and squirtpowerful jets at the sea floor, excavating burrowing invertebrates such asclams and may consume 3,000-6,000 clams within a single feeding.
  • Theprimary functions of the walruses' prominent tusks seem to be aiding in haulingout on ice and rocky shores and in establishing social dominance.

Waterbuck

waterbuckSitatungas(Naakong) are even more specialised than red lechwe, feeding only on aquaticvegetation. The sitatunga have splayed hooves to enable them to walk in thewater. These animals are very shy and can be seen especially well when thewater is very low."Water Kudu" is the Afrikaans translation for thesitatunga. As with the bushbuck, sitatunga are also members of the Tragelaphusfamily (Kudu and Nyala are other members). 

Whale

whaleA mammal, by definition, breathes air into thelungs, is warm blooded, feeds its offspring milk and has body hair. Mammalsevolved from reptiles some 70 million years ago and some like whales returnedto the waters approximately 16 million years after leaving it. The platypus isa duck-billed, beavertailed and otter-footed poisonous mammal that is alsospecial because it lays eggs. However, the eggs develop in the uterus for amuch longer time than that of egglaying non-mammals and the young ones are fedmilk — something unique to mammals. It is believed that monotremes (the classof platypus-like mammals) branched from other mammals early in evolution. Theother mammals evolved into either placental or marsupial groups. The class ofmammals that evolved into whales do not lay eggs at all.

White Bengal Tiger

white-bengal-tigerWhitetigers are very rarely found in the wild. In about 100 yeas only 12 whitetigers have been seen in the wild habitats of India. They are almost extinct andmost of the ones living are in captivity, mainly in zoos. This specific tigeris neither an albino or a seperate subspecies of the tiger. They are simplywhite colored and have black stripes that makes them special. It has blue eyesand a pink nose. It also has prestine white colored fur. The white tiger isborn to a bengal tiger that has the recessive gene needed for white coloring. Apure white tiger has no stripes and are completely white in color.
