How does a sea otter move?

Sea otters spend a great deal of time floating on their backs at the surface. They move by paddling their hind limbs and sculling with their tails. For rapid swimming and for diving, they swim similarly to other otters, using up-and-down undulations of the body.

What is the Sea otters niche?

Ecological niche Sea otters play a big role in their ecosystem by controlling herbivorous invertebrates. They prey on sea urchins, preventing them from overgrazing the forest of kelp, which supports marine diversity. The variety in their diet supports greater diversity amongst benthic grazers.

What is a Sea otters life cycle?

Pups start diving within two months. LIFE CYCLE: Male sea otters live between 10 and 15 years, while females live slightly longer, from 15 to 20 years. FEEDING: Underneath each of the sea otter’s powerful front paws is a pouch to store food collected during foraging dives.

How do Sea otters protect themselves?

What’s so special and unique about a sea otter’s fur?

What is a group of sea otters called?

How are river otters different from sea otters?

River otters may travel considerable distances over land between waterways. Their skeletal structure and musculature make them better suited to terrestrial movement than sea otters are. River otters can attain running speeds up to 47 kph (29 mph). They travel over snow and ice using a combination of running and sliding.
