Marco Salewsky caught this very unusual fish from the wharf in Port Charles on the Coromandel. It measured 1.80 meters. Marco caught it on 31 October 2015. Congratulations Marco – I think! This is a rare and unusual catch in New Zealand waters. The fish is a sand snake-eel, Ophisurus serpens, which is an eel of the genus Ophisurus. Snake eels are usually found buried in the sea bottom sand and sediments with just their eyes and part of the mouth visible. They can grow to over 2.5m but even really long ones are usually less than 50mm (2 inches) in diameter.
