Question

features of animal seal and how are they adapted to their habitat

Answer 1

A seal has much shorter limbs than most mammals: what appears to be an armpit & groin of a seal are, in fact, the equivilant of the wrist and the ankle.
By comparisons, the bone of their flippers are enormously long, and the skin btw them forms a web which is used lyk a paddle to propel the seal along. They have long, sturdy claws on their front flippers, which they use to help them move on land, especially when they need grip.

Most mammals need to maintain a body temperatue of 37°C. The sea is much colder then this , and conducts heat away from the body, much faster then air does. Seals have a hairy coat, which trap air and uses it as an extra insulating layer. Far more important is the layer of fatty tissue beneath the skin, called blubber.

Senses:
sight- their eyes has adapted the environment , which help them to see underwater.
hearing-their ears have adapted to hear on land as well as underwater.

WOW fact :
Seals have been known to dive as deep as 4,100 meters and can remain sumberged up unto an hour.
