Short Description
The smalleye pygmy shark, Squaliolus aliae, is a very small dogfish (about 22cm) characterized by its small eye, with diameter about 46-70% of interorbital width, and with upper margin angular and chevron-shaped; upper lip with a pair of prominent lateral papillae (rarely indistinct) [544] [1388].Colour: dark brown to black, fin margins pale [1388]. Squaliolus are the only sharks with a fin spine on its first dorsal fin (spine sometimes concealed by skin) but not on its second dorsal fin; second dorsal fin long-based and low, about twice the length of the first dorsal fin base; first dorsal-fin base closer to pectoral fins than to pelvic fins; and caudal fin nearly symmetrical, with subterminal notch present [518] [1388].

Biology
Distinct pairing with embrace [17086]. Ovoviviparous but litter size unknown [1388]. Males mature at 15 cm [544]. Possibly the smallest living shark . Found near continental and island land masses. Feeds mainly on cephalopods and small midwater bony fishes.
