Everyone knows that most seals eat fish. Once the seals swim briskly all winter and support the holes, then in the frozen sea they find their food. It is known that they are found almost everywhere where there is polynyas. Occasionally they get almost to the very pole, so there is a fish there.
The most numerous fish living in the Arctic under the ice and close to the watercourses belong to the cod family. The basis of the menu of the main anglers in the polar winter, seals and beluga whales is the Arctic Fox, or the polar trot. It lives both near the coasts and under floating ice throughout the Northern Polar region. The temperature of the water in which the seal lives, never rises above zero degrees Celsius.
These fish eat small creatures that live in the water column – plankton.
The name “plankton” comes from the Greek plankton, which means wandering, worn, soaring. This group includes organisms that are united “not by kinship or community of structure, but by a similar way of life. It’s like a profession in nature. To a plankton, a living creature can be attributed, if, in the water column, it can not move sufficiently energetically to resist currents. Planktonic creatures move actively up or down without the help of currents. Depending on the conditions of life, they go deep or rise closer to the surface.
