Description

The Batavia batfish is a spadefish (Ephippidae) from the Indo-West Pacific. The species reaches about 65 cm and has a very deep, strongly compressed, disc-shaped body. Juveniles are strikingly black-and-white striped; this zebra pattern provides camouflage and makes them resemble a toxic flatworm. Adults are silvery and usually live solitarily on continental reefs, on open substrates with sparse coral, often at some depth. They feed on algae, sponges, tunicates and small invertebrates. The species is regularly eaten and kept in large marine aquaria.
