Binomial name: Odonus niger, Eduard Rüppell, 1836
Odonus niger also known as the Red-toothed triggerfish is a triggerfish of the tropical Indo-Pacific area, the sole member of its genus.
The redtoothed triggerfish is a dark blue bodied fish, ranging up to 50 cm in length. The fins are all blue-green in color, having yellow and light blue trim. It has a lyre shaped caudal fin with a yellow bar between the lobes. Like all triggerfish redtoothed triggers have a retractable dorsal spine.
Their pectoral fins are quite small; as a result they steer mostly with their dorsal and anal fins, which makes them very maneuverable, and they also use these fins to move with an exotic type of propulsion reminiscent of a propellor. It is one of the most singular swimming styles in the ocean.
It inhabits open waters and current-swept seaward reefs between 0 to 35 metres (0–115 feet) and can often be seen in groups turning and circling just under the sea surface while feeding on plankton brought in by the current. Sponges are another part of their menu.
