توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل) : 6 - 7; شعاع نرم باله مخرجي: 4 - 5. Metamorphosed males and females have an extremely long pectoral fin lobe, bearing high number of pectoral fin rays, inserted along dorsal margin and an elongate, slender subopercular bone, tapering only slightly, dorsal end rounded or squared off. Metamorphosed females are further unique in having the following characteristics: presence of vomerine teeth; convex dorsal margin of frontal bones; reduced sphenotic spines; lower jaw with small symphysial spine; hyomandibula with double head; small quadrate and articular spines; deeply notched posterior margin of opercle; elongate and slender subopercle throughout its length, ventral end elongate and rounded; well developed second pharyngobranchial; caudal fin rays without internal pigmentation; illicium longer than length of esca bulb; pterygoiphore of illicium cylindrical throughout its length, emerging on snout from between frontal bones, anterior end exposed, posterior end concealed beneath skin; well developed first ray of dorsal fin; dorsal fin rays 6-7; anal fin rays 4-5; extremely long and narrow pectoral fin lobe, longer than longest rays of pectoral fin; pectoral fin rays 28-30; skin presumably naked, without dermal spinules; darkly pigmented skin of caudal peduncle extends well past base of caudal fin (Ref. 86949). Metamorphosed males: have 13 olfactory lamellae; 9 upper denticular teeth arranged in two rows, inner row with 8 teeth, outer row with 3 teeth; naked skin, without dermal spinules (Ref. 86949). Larvae: elongate body; depth of body and length of the head measures 40-45% of SL; concentration of pigment lies medial to subopercle; dorsal pig mentation restricted to anterodorsal part of body (Ref. 86949).
Body shape (shape guide): short and / or deep.
