Although their sights mainly react to movement, their auditory perception helps them become dangerous killers. They can hear black grouse changing roosts at 600 paces, crows flying at 0.25–0.5 kilometers and mice squeaking at about 100 meters.

2. Moose

This animal also refers to Elk. It is the largest species in deer family. Unlike other deer species, moose do not live in a group. Although it is slow and appears to be harmless, it can be aggressive when disturbed.

Since moose is herbivore, it can eat any kind of plants and fruits. They mainly eat forbs and fresh shoots from trees, like birch and willow.

Moose is a prey for some big carnivore, like brown bear and Siberian tiger. There is also smaller kind like grey wolves that can attack female.

Biomass of this population is about 150 thousands tons and occupies 70% of fish population in Lake Baikal. Thus, making them easily to be found in shallow water.

5. Amphipoda

Amphipoda belongs to order of malacostracan crustaceans with no carapace, or upper part of the shell. Most of them are marine animals and are scavengers.

There are 13 segments in body of an amphipoda that include head, thorax and abdomen. Their size usually does not exceed 10 cm, but the largest recorded amphipoda is 28 cm long. Meanwhile, the smallest one is 1 mm. The difference in size is due to the difference amount of dissolved oxygen they can have.

Most of them are scavengers. However, there are some of them which are omnivores, predators of small insects or grazers of algae.

6. Lubomirskia baicalensis

This animals is a kind of sponges. It also refers to Lake Baikal sponge. There are a lot of this kind of sponge in Lake Baikal although 14 species of Lubomirskiidae family are Baikal endemics. They can be found in the depth of 1 to 120 m.

In shallow water, it appears like a carpet. Meanwhile, in the depth of 3 to 4 m, their height can reach up to 1.2 m, which is considered large for sponge. At that height, it starts to grow branches. Meanwhile, in the depth of 5 to 12 m, it can grow wider branches and may form “forest.”

The green color of this sponge comes from mutual symbiosis with green dinoflagellate. Moreover, dinofalgellate can produce okadaic acid so this sponge can survive when Lake Baikal is covered with ice.
