The Sea -Cow :-
It lives in groups and after the whales there is such a lactational group of sea-cows . who have developed the compatibility of living in the sea at kalawati .
Like a whale , not even a part of the sea cow's limb . The front of them is like the flippers and these is no how on the skin .
There is no genealogy relationship between the whale and the sea-cow group . Because the ancestors of the whale were carnivores . While the the ancestors of sea - cows were vegetarian . There are four varieties of sea - sows .
A variety is called dugong and the other three varieties are called manatees . Dugong variety is found in the Indian Ocean from the indians Ocean to the northern shores of Australia .
It's length reaches 8 or 9 feet . Ways to climb Dugong and manatees are different . Dugong's lip is big enough . Because the Ocean is the grazing creature so their teeth fall down . The old teeth of the next fall and the new teeth come from behind .
