Short description

Dorsal spines (total): 1; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. The spined pygmy shark Squaliolus laticaudus is a very small dogfish (about 25cm) with a large eye (diameter 73-86% of interorbital width), upper margin nearly straight; upper lip without papillae (Ref. 31367, 6871). Color: dark with conspicuously light-margined fins (Ref. 247) . Edge of fins with bright border (Ref. 43998). S. laticaudus is the type species of the genus which has the following distinctive features: fin spine on its first dorsal fin but not on its second dorsal fin; second dorsal fin long-based and low, about twice the length of first dorsal fin base; first dorsal-fin base closer to pectoral fins than to pelvic fins; and caudal fin nearly symmetrical, paddle-shaped, with subterminal notch present; low lateral keels on caudal peduncle . Body cigar-shaped; snout very long, bulbously conical but slightly pointed; mouth ventral; lips thin; teeth strongly different in both jaws, uppers small, narrow and erect cusps, lowers larger, blade-like and semi erect. Tooth rows 22-23/16-21. (Ref. 247, 6871).

An oceanic, wide-ranging, tropical pelagic species occurring near continental and insular land masses, sometimes over the shelves, but usually over the slopes (Ref. 247). Displays vertical migrations on a diel cycle, seen at the bottom during the day and travels to 200 m at night (Ref. 247). Feeds on deepwater squid, lanternfish, gonostomatids and idiacanthids, and probably follows its prey on their diel migrations (Ref. 247). Ovoviviparous (Ref. 205). Has well-developed photophores densely covering the ventral part of the body and sparsely seen on the sides and hardly developed on the dorsal surface (Ref. 247).
