Marine arctic animals use their fat stores for buoyancy and insulation. The fat is made into a specialized form called blubber.

Yes, many species of animals live in the Arctic. These include land animals such as caribou, polar bears, Arctic hares, and Arctic fox, as well as a variety of birds and insects. In the ocean, there is a variety of fish and many marine mammals, such as whales, killer whales, and sea lions.
Blubber is an external layer of fat found beneath the skin of certain animals, primarily marine mammals like whales, seals, and polar bears. It serves as insulation to help regulate body temperature in cold environments, as well as providing energy reserves and buoyancy.

Th Arctic tundra refers to cold, flat lands that always have a layer of frozen soil a few inches below the surface, called permafrost. Because marine animals by definition live in the ocean and not on land, there aren't marine animals in the tundra. However, many marine animals such as fish, killer whales, sea lions, and more live in the Arctic, and a few, such as sea lions, may rest on the shoreline of the tundra.
Dolphins are mostly covered with smooth, streamlined skin that is typically a mix of gray and blue hues. Their skin is composed of a layer of blubber underneath, which provides insulation and buoyancy. Unlike many other marine animals, dolphins do not have scales; instead, their skin is often described as rubbery and is adapted for efficient swimming in the water.
No, snowy owls do not have blubber. Unlike marine mammals that rely on blubber for insulation and energy storage, snowy owls have thick feathers that provide insulation against cold temperatures. Their feathers are specially adapted to keep them warm in their Arctic habitats. Additionally, they have a layer of down feathers beneath their outer feathers for added insulation.
The type of fat that many marine mammals have is called blubber. Blubber is a thick layer of fat located beneath the skin, providing insulation to help maintain body temperature in cold water environments. It also serves as an energy reserve and aids in buoyancy. This adaptation is crucial for survival in the often frigid habitats of marine mammals.

Buoyancy plays a crucial role in ocean dynamics by influencing the distribution of water masses and the movement of marine organisms. It affects how different layers of water, which vary in temperature and salinity, interact, leading to stratification and the formation of currents. This stratification impacts nutrient transport and the overall health of marine ecosystems, while also affecting climate patterns through processes like thermohaline circulation. Additionally, buoyancy influences the buoyancy of objects, including marine life, which must adapt to their surroundings for survival.
