- Group
- Ocean animals
- Order
- Pleuronectiformes
- Family
- Pleuronectidae
- Genus
- Kareius
A fish of sandy and muddy sea bottoms from Hokkaido to Kyushu, and around the Korean Peninsula, Sakhalin and the Kuril Islands.
Rows of stone-like bony plates line the eyed side of its body, and they gave the fish its name.
How the Stone flounder lives
Small young fish in Sanbanze feed on zooplankton. In Sanbanze, the growing young eat bottom-dwelling animals such as bristle worms and amphipods. In Sanbanze, further growth brings a more varied diet, including Manila clams.
