Unique Ecosystem - Marine Life
The blue bat star is one of the most commonly seen starfish along the coast of Japan. It inhabits the rocky reefs and sandy intertidal zones to depths of 300 m. It is grey in colour with patches of orange, forming different patterns on each individual. The starfish is about 10 cm in size and prey on crabs, hermit crabs and shellfish. The blue bat star normally has five arms. The shape of the starfish, which looks like a spool, gave it its Japanese name.
