Starry Seabat, Halieutaea stellata Vahl, 1797
Starry Batfish, Starry Handfish
Introduction
Fishes in the genus Halieutaea have the head expanded into a flat, circular disc. The upper surface has scales modified into spiny tubercles. The fish in the video below might not be H. stellata, but the footage is so interesting, it just had to be shared!
Identification
Batfishes have a fleshy lure (the esca) on the snout. The esca is positioned within a bony recess called the illicial cavity.
The pectoral fins project laterally at the rear of the disc. The pelvic fins are located on the under side of the disc.
The Starry Seabat is usually red to pink dorsally with fine black or grey spots forming crescentic patterns. The pectoral, caudal and dorsal fins are red, usually with black margins.
Distribution
It is a benthic species that occurs throughout the tropical Indo-West Pacific.
The map below shows the Australian distribution of the species based on public sightings and specimens in Australian Museums. Source: Atlas of Living Australia.
