How do harp seals survive?
With a thick layer of blubber under their skin, harp seals are able to hold their body heat more easily. This layer of fat also provides a means of buoyancy, stores energy, and gives the seals a shape that is better suited for the aquatic environment where they are often found.
How do sea lion protect themselves?
