The Tailfin Batfish (Platax teira) is also commonly referred to as the ‘Longfin Batfish’ and both names are derived from the extremely long dorsal and ventral fins; particularly in the juveniles. This species is common in the tropical waters of the Indo-Pacific region and is known to occur from the Red Sea and east Africa across to Melanesia and New South Wales in Australia. This species can be found in schools particularly around popular dive locations where fish are regularly fed. This species looks similar to the Round Faced Batfish (Platax orbicularis) however the Tailfin Batfish has thicker black bands and usually has a black blotch in the lower part of the band behind pectoral fin. Juveniles often float near the surface mimicking drifting leaves and vegetation whilst schools of large juveniles may be encountered under sargassum rafts. The Tailfin Batfish (Platax teira) is known to occur to depths of 30 metres and grows to a maximum length of approximately 60cm.
