Celebes Monkfish, Sladenia remiger Smith & Radcliffe 1912

More Info


Off North West Cape to the Exmouth Plateau, Western Australia, and the Coral Sea, Queensland, to the St. Helens seamount area, south of Tasmania. Elsewhere the species occurs the west-central Pacific: off Sulawesi, Indonesia, the Kermadec Ridge off northern New Zealand, and off Hawaii.
Inhabits deep-sea rocky areas on seamounts ridges and rises on the continental slope.


Dorsal fin III, 9; Anal fin 7; Pectoral fin 19; Pelvic fin I, 5; Caudal fin 8 (outer 2 rays unbranched); Vertebrae 19.

Head short (~27%SL); snout long (~75% HL); head spines well developed, frontal spines greatly enlarged.


The specific name is from the Latin remus (= oar) and -iger (= bearing), possibly in reference to the paddle-like pectoral fins of species of the genus Sladenia.
