Tigers usually grow to lengths of more than nine feet and can be bigger than the largest lion. They 
have great strength. They clutch their prey to them, holding on with their claws, and depend on the 
crushing bite of their powerful jaws. They swim very well and can often be seen splashing about in 
water on very hot days, as they apparently suffer from the heat. When the air is cool, however, they 
avoid wet or damp vegetation. They can climb, but do not approach the leopard's ability in this. They 
can survive in rocky areas but generally prefer to stay on level ground. They are not as well equipped 
with senses as one might expect. They apparently depend on their hearing while hunting. Their 
eyesight is not particularly good, and they cannot spot prey until it moves.
