In unit two suborders: toothed and baleen whales.
Baleen whales – 10 species are the biggest animals. Their food – small organisms, plankton, whales strain out of the water a unique structure – whale baleen, which is a set hanging on the upper jaw parallel long horn plates with split rear edge.
Keith is gaining in the mouth water and pushes it back through the bars that holds the food in your mouth.
Because this type of power suborder called “baleen whales”.
Toothed whales – mostly small (compared to baleen whales) animals that feed mainly on fish and squid. In water oriented and hunt using echolocation: emit ultrasonic signals and perceive their reflections. This allows you to judge the size, location and speed of production. The number of teeth in toothed whales, depending on the species, ranges from 2 to 200.
In Anapa Dolphinarium are living representatives of two species belonging to the suborder of toothed whales: Beluga whales and bottlenose dolphins.
