How are seals and sea lions adapted to their environment?

Their thick blubber layer aids in temperature control. Sea lions have the ability to direct oxygen-rich blood to critical organs where it is most needed.
What are the adaptations of a seal?
Seals are remarkably adapted to ocean living. These aquatic mammals have powerful sleek bodies that are encased in blubber and taper down into a tail. Their thick no-neck physiques and loosely interlocked vertebrae make them strong and flexible enough to surf the waves and navigate ice and rocky shores.
How are seals and sea lions alike and different?
Seals and sea lions are marine mammals called ‘pinnipeds’ that differ in physical characteristics and adaptations. Sea lions (left) are brown, bark loudly, “walk” on land using their large flippers and have visible ear flaps. Seals have small flippers, wriggle on their bellies on land, and lack visible ear flaps.
Why are sea lions better adapted to live on the land than seals?

How deep can a seal dive?
Adult harbor seals can dive as deep as 1500 feet and stay underwater over 30 minutes! To do this, they rely on their amazing oxygen storage capabilities. Harbor seals have a grater volume of blood than other land mammals their size.
Do seals sleep underwater?
Seals sleep in the water as well as on land. In the water, they sleep floating in a standing position, like a fishing bobber, or floating horizontally on the surface. Because they are sleeping and not actively swimming, they can stay under water much longer than when hunting for food.
