Robust Ghost Pipefish

Robust ghost pipefish hover head-down in pairs among seagrass and algae, their mottled brown and green coloration so convincing as vegetative debris that only movement betrays their presence. They feed by sucking small crustaceans into their tubular snouts with a rapid vacuum strike, and their pair-bonding behavior — where male and female maintain proximity for extended periods — is exceptionally rare among fish and appears to increase reproductive success in the patchy habitats of the Madang slope.
