5 The spined pygmy shark is one of the smallest sharks; it is roughly 7 to 8 inches (18 to 21 cm) long (females are about 8 inches fin but not in front of the second dorsal fin (this is unique among sharks). It also has a luminescent (glow-in- the-dark) belly. This harmless shark is very sleek and has a bulbous snout. It has a large spiracle (an extra, round gill slit) behind each large eye. It is dark-gray to black with white-tipped fins and bio-luminescence (luminous photophores) on its belly; these photophores light up and may serve as camouflage (they eliminate shadows when seen from below).spiracle
