Sea otters belong to animals in the order Carnivora, so they are carnivores from the point of view of feeding habits, mainly eating meat. And because sea otters often move in the sea, their main food is some marine animals. Specifically, there are many kinds, such as sea urchins, shellfish, abalone, crabs and some marine fish. Among these foods, sea otter's favorite food is sea urchin. In addition to these meats, sea otters sometimes eat algae in the water, but not often, and they are mainly carnivores.
Sea otters eat a lot. They can eat a lot of food in a day, which can be equivalent to about one third of their body weight. Therefore, they hunt and eat in the water for a very long time.
As mentioned above, sea otters belong to carnivores, and sea urchins are one of the main foods of sea otters. In fact, among all the foods, sea otters like to eat sea urchin most. However, sea urchins have a hard shell on the outside, which sea otters can not easily break open.
At this point, they will first keep the sea urchin in their armpit pockets, and then float to the surface of the water to lie down on their backs. At this time, they will take out the sea urchin in the pocket and put it on their stomach, then take out the small stones prepared in the pocket and knock the shell of the sea urchin. After a while, they stop to see if the urchin's shell has been smashed, and then they eat it, and if not, they continue to smash it. After eating, sea otters will put the stones back into their pockets, and if there are any sea urchins left, they will put the remaining sea urchins back into their pockets.
