This fridge-friendly feature means that the seals blubber can insulate the animals internal organs without fighting to keep the exposed skin warm. Seals can also get energy from the blubber if they haven't eaten in a long time. Image credit: Kooyman GL (1973) Respiratory adaptations in marine animals. When blood circulates close to the skin, precious body heat is lost. Arctic foxes are also a popular food source for seals. According to a new study published in the journal Scientific Reports, seals appear to stop shivering not because they are trying to generate heat, but because they have turned off the insulation that causes them to shiver. Sometimes native animals find themselves in an environment to which they cannot adapt. Like all mammals, seals need water, but you rarely catch them at the company drinking fountain.

In contrast, seals, like us, keep their internal body temperature stable at 37 degrees Celsius. Seals are marine mammals that live in cold coastal and ocean environments. Seals can also get energy from the blubber if they haven't eaten in a long time. This enables them to breathe when necessary.
