Trumpetfish (fugm10 / CC BY)

The trumpetfish (Aulostomidae) has an elongated body, a long tubular snout, and a small upturned mouth. Trumpetfish can grow up to 1 meter (40 inches, Aulostomus maculatus) in length and they inhabit shallow coastal waters up to a depth of about 120 meters (393 feet). Typically found near reefs and in weedy areas, trumpetfish sometimes swim vertically (snout-down) among branching gorgonians or corals.

Inhabits the Atlantic Ocean.
