This snail-like sea predator lives in the waters of the Japanese Sea. Limainas float around and feed on small planktonic organisms.
These creatures are truly magnificent. They live in deeper waters during the day and go to the surface at night to feed. Whales, sea birds and herring catch Limacinas at night when they come to eat plankton.
These images were captured by Andrey Shpartak – a spectacular diving photographer from the Russian Far East.
