Banded Sea Snake Laticauda colubrina on a outer reef swimming to surface, looking for fresh water. Sea Snakes need to drink fresh water and regularly come onto land for that purpose. The Banded Sea Snake Laticauda colubrina occurs in tropical Indo-Pacific. Males maximum length 88 cm, females 142 cm. The Banded Sea Snake is often seen in large numbers in the company of hunting parties of giant trevally (Caranx ignobilis) and goatfish. Their cooperative hunting technique is similar to that of the moray eel, with the Snakes flushing out prey from narrow crevices and holes. \nThis specimen was encountered in the Triton Bay, Kaimana Regency, West Papua Province, Indonesia, 3°55'0.7321 S 134°6'7.7298 E.

The reedfish, ropefish (more commonly used in the United States), or snakefish, Erpetoichthys calabaricus, is a species of fish in the family Polypteridae alongside the bichirs. It is the only member of the genus Erpetoichthys. It is native to fresh and brackish waters in West and Central Africa. The reedfish possesses a pair of lungs in addition to gills, allowing it to survive in very oxygen-poor water. It is threatened by habitat loss through palm oil plantations, other agriculture, deforestation, and urban development
