The thick-headed or high-backed Anthias ( Serranocirrhitus latus ) is a small fish from the family of saw basses (Serranidae). It occurs in the tropical, western Pacific from the Moluccas , over the Great Barrier Reef to Fiji , New Caledonia and Tonga , north to the Izu Islands and Taiwan .

features

The thick-headed anthalis becomes 13 cm long. It can be distinguished from almost all other anthropoid species by its tall figure. The back, top of the head and partly the flanks are yellow, the underside with the paired fins is orange-red in the males, in the females rather purple. Characteristic are two yellow stripes that extend from the eye over the cheeks to the gill cover.

Fin formula : dorsal X / 18–20, anal III / 7.

Way of life

The thick-headed anthias live very hidden individually, in pairs or in small, loose groups closely tied to coral reefs . He always stays near caves or other shelters on outer reef slopes at depths of 15 to 70 meters. He always turns the underside of his body towards the closest solid substrate, he stays in caves or under overhangs near the ceiling, so he swims with his stomach up. It feeds on zooplankton .

Systematics

The author of the first description , Watanabe, noticed in the investigation of the fish similarities with the saw bass and the tufted perch (Cirrhitidae), assigned the fish to the tufted bass and emphasized the similarities with both families through the scientific generic name Serranocirrhitus . The similarity with the mongoose is also emphasized by the English name Hawkfish anthias .

In 1962 the fish, the type specimen here was a specimen slightly different in color, was described a second time by the Australian ichthyologist Whitley under the name Dactyanthias mcmichaeli . It was not until 1978 that the American ichthyologist John Ernest Randall and the North American-South African ichthyologist Phillip C. Heemstra noticed the double description, synonymized Dactyanthias mcmichaeli with Serranocirrhitus latus, and assigned the fish to the anthias (Anthiadinae), a subfamily of the sawfish. A direct comparison of the type specimens by Watanabe and Whitley was no longer possible at this point, as Watanabe's specimen had already been "disposed of" by US marines in Tokyo Bay in December 1945 .
