teira, also known as the teira batfish, longfin batfish, longfin spadefish, or round faced batfish is a fish from the Indo-West Pacific. It occasionally makes its way into the aquarium trade. It grows to a size of 60 cm (24 in) in length. Platax teira has a dark blotch under the pectoral fin, with another long dark mark above the base of the anal fin. Looked at from the side, it has a roughly circular body with a low hump on the nape. This fish is usually silver, grey or brownish. It has a blackish band through the eye and another band with the pectoral fin. They will change colour from silvery white with no bands, to brown with darker banding as you watch, and then fade back to silver again.
