extremely protrusible, capable of being extended forward more than half the length of the head. The jaws swing forward into a long tube that uses strong suction to catch

Habitat and Ecology:

Inhabit coral-rich areas of lagoon and seaward reefs commonly at depths of 5-6m (depth range 1-42m). Generally solitary.  Feeds mostly on shrimps, crabs and small fishes.
Spawns in harems with male patrolling mating territory. When catching prey, the highly protrusible jaws swing forward into a long tube to suck prey into the mouth.

Fishery Status:

This species is not protected or subject to fishery regulations. It is caught occasionally in the fish trap fishery but more typically in nets that have been dragged on the 
substrate, it is usually an uncommon to rare component of the catch.
