Size / Vikt / Age
Könsmognad: Lm ? range ? - ? cm
Max length : 14.2 cm (female)
Mjukstrålar i ryggfenan (totalt) : 83 - 87; Mjukstrålar i analfenan: 51 - 54; Ryggkotor: 54 - 56. This species is distinguished from it congeners by the following characters: gill filaments on anterior arch is 4-5 times the length of the developed rakers; a pair of very small, subdermal, closely set spines on frontal plate above and behind eyes, absence of spine on ethmoid; anterior arch with 2-3 developed rakers, not much longer than spiny knobs; gill filaments on anterior arch 4-5 times length of developed rakers; palatines 2-4 tooth rows; prolonged pectoral peduncle adnate to body; vertebrae, precaudal 14-16 and total 54-56; fin rays, D 83-87, A 51-54, caudal 12-13, pectoral 17-19 (Ref. 93007).
Cross section: oval.
Rare species, known from two specimens (Ref. 34024). A viviparous species living on the lower part of the continental shelf (80-150 m). Four examined female specimens are with well-developed eggs but apparently no embryos. Sections of ripe testes show that the spermatozoans are arranged in spermatophores (Ref. 93007).
