Japanese silverside biddy is a small marine fish with a tall silvery body. It lives in coastal waters of the western Pacific Ocean and feeds on the sea bottom.
Japanese silverside biddy differs from related species by its high body and lack of bright stripes on the sides. It is important for nature as a link in the food chain: it eats small animals and serves as food for larger fish.
Immature form that undergoes metamorphosis before adulthood.
