Polar Whale
Polar whales are a group of marine mammals that are specifically adapted to survive in the cold, icy waters of the Arctic and Antarctic regions. These whales have thick layers of blubber to insulate them from the frigid temperatures, as well as a streamlined body shape to help them move efficiently through the water. They also have specialized adaptations, such as a thick layer of fat called "melon" on their heads to help them navigate under the ice, and the ability to hold their breath for long periods of time while diving for food. Some common examples of polar whales include beluga whales, narwhals, and bowhead whales.
