More Info


Endemic to eastern Australia from Swain Reefs, QLD (22°24'S) to off Sydney, NSW (33°40'S).


Vertebrae 30-31 (10 + 20-21).
Head and body moderately compressed (body width 1.3- 1.55 in depth in adults); 3 dorsal-fin spines; a low naked fleshy nuchal crest; dorsal angle of opercular bone broad, not forming a distinct exposed, pointed spine; vomer and palatines edentate; subopercle and preopercle entire; scales including those on head and pelvic region large and ctenoid; interorbital with a single row of large scales, extending to, or just beyond anterior margin of eye; suborbital scales reaching a vertical between anterior margin of pupil and anterior margin of eye.


Simipercis is from the Latin 'similis', for similar or like, in reference to the pinguipedid genus Percis Bloch and Schneider, 1801 (the latter being preoccupied by the agonid genus Percis Scopoli, 1777). The specific name trispinosa if from the Latin 'tres' for three, and 'spina' for thorn or spine, in reference to the 3 dorsal-fin spines, a character state not found in any other species of Pinguipedidae.
