to protect them from weather condition
Layers of fat can keep dolphins warm in cold waters and block harmful UV rays from the sun from reaching it's organs, as well as store extra energy and deflect shallow bites from causing mortal wounds.
i think that the skin keeps them cool and doesnt the dolphins get to hot or to cold
A dolphin has body fat equaling 18-20 percent of total body weight. This fat is deposited into a thick layer called blubber, which is used to provide insulation to dolphins and helps in conserving body heat.
Penguin have a thick lay your fat bunder
They have a thick layer of fat so they can keep warm.
Dolphins, porpoises and whales have a thick layer of fat beneath the skin to insulate them so that they do not lose too much body heat in the water. That's the blubber.
a thick layer of fat or fur
A thick layer of fat.
In the Arctic or Antarctic, probably on land. Polar bears and musk ox fit that description. Most marine mammals (in cold climates) have a thick layer of fat, but lack a thick layer of fur. However, the nine species of fur seals have thick fur.
they have long hair and a thick layer of fat
blubber
Many animals including whales, seals, manatees and penguins have a thick layer of fat called blubber. Only marine animals have blubber (but not every marine animal). Blubber provides buoyancy, hydrodynamic shape, and stores energy.
