Chimaera stellata, the stellated chimaera, is a type of chimaera of the family Chimaeridae found exclusively in Okinawa Trough, East China Sea, from only one specimen.[2][1]
Description
[edit]This chimaera species is distinguishable from its closest congener (Chimaera owstoni) from several characteristics: stockier body, robust head, slightly concaved dorsal spine, teardrop-shaped pectoral fin, square-shaped anal fin with pale gray distal margin, darkish ventral surface, and walnut brown-colored body with lighter spots.[2] The only specimen ever reported, which is a female, has a maximum total length (TL) of around 88.7 cm.[2]
Habitat & distribution
[edit]After its discovery, stellated chimaera has been believed to be an endemic in Japan, specifically around Okinawa, and there are still no details about its habitat depth.[2][1]
