Pipefish (Alain Feulvarch / CC BY)
The pipefish has an elongated, slender body encircled by bony rings. It is named for its pipe–like snout. Like seahorses, most pipefish species are poor swimmers. Pipefish typically range from 5 centimeters (2 inches, velvet ghost pipefish) to 40 centimeters (15.7 inches, slender pipefish) in length. They are commonly found in sheltered areas of coral reefs or sea grass areas. Pipefish males incubate the eggs, which are attached to an external brood pouch.
