Etymology: Acanthochaenus: Greek, akantha = thorn + Greek, chaino = with the mouth opened (Ref. 45335).
Eponymy: Professor Christian Frederik Lütken (1827–1901) was a Danish naturalist, specialising in marine zoology. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecologia
marinhas bentopelágico; intervalo de profundidade 1655 - 5397 m (Ref. 58018). Deep-water; 40°N - 57°S, 77°W - 164°W
Atlantic, Indian and Pacific: in subtropical and temperate waters (Ref. 50895). In the Indian Ocean known localities include the Madagascar Ridge (Ref. 51654) and the West Australian Ridge, Naturalist Plateau.
Length at first maturity / Tamanho / Peso / Idade
Maturity: Lm ?, range 12 - ? cm
Max length : 15.2 cm TL macho/indeterminado; (Ref. 41039)
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 11; Espinhos anais: 1; Raios anais moles: 9 - 10. Body scales are spiny (Ref. 37108). Body elongated, almost cylindrical, somewhat compressed (Ref. 10920). The snout protrudes forward above upper jaw, its length 3.4-4.4 times in head length, eyes fairly small, upper jaw extends beyond the posterior border of the eye. Dorsal and anal fins are opposite one another (Ref. 10920).
Adults probably benthopelagic (Ref. 51654). Larvae taken at 30 m (Ref. 51654). Benthic crabs Malacostraca were found in the stomachs of 3 specimens SL 8.5-9 cm from Madagascar Ridge (Ref. 10920).
