Its good to know..
The lion ( Panthera ) is one of the four big
cats in the genus Panthera and a member of the
family Felidae. Wild lions currently exist in sub-Saharan Africa and in Asia while other types of
lions have disappeared from North Africa and Southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago,
the lion was the most widespread large land mammal after humans. In Asia there
are 240 lions more. Lions live for 10–14 years in the wild, while in captivity
they can live longer than 20 years.
Bears are mammals of the family Ursidae.
There are 8 species. Popular species are the brown bear, the black one and
polar bear. Bears have been hunted since prehistoric times
for their meat and fur.
Polar bear can detect seal under 1 meter ice.
The
bears are eating everything, except the polar bear that is eating
seals.
Elephants are large mammals. The largest living animal, male African elephants can
reach a height of 4 m and weigh 7,000 kg . Their trunks grow into tusks, which
serve as tools for moving objects and digging and as weapons for fighting. The
elephant's large ear flaps help to control the temperature of its body. African
elephants have larger ears and concave backs while Asian elephants have smaller
ears and convex or level backs. The trunk of the elephant have 40 000 muscles, more then one human
body.
Dolphins. There are almost forty species of
dolphin. They vary in size from 1.2 m and 40 kg (Maui's dolphin),
up to 9.5 m and 10 tonnes (the Orca or
killer whale). Dolphins are among the most intelligent animals, and their
often friendly appearance, an artifact of the "smile", and seemingly
playful attitude have made them very popular in human culture.
Gorillas comprise the eponymous genus Gorilla, the largest extant genus of primates by size. The DNA of gorillas is highly similar to that of a human, from 95–99% depending on what is counted, and they are the next closest living relatives to humans after the bonobo and common chimpanzee.
Gorillas' natural habitats cover tropical or subtropical forests in Africa.
Crocodiles are large aquatic tetrapods that live throughout the tropicsin Africa, Asia,the Americas and Australia. Although all crocodiles are anatomically and biologically similar; their size, morphology, behavior and ecology somewhat differs between species.They first separated from other crocodilians during the Eocene epoch, about 55 million years ago.
