Description

The blacksaddle snake eel is a snake eel from the Indo-Pacific, ranging from Myanmar to the Society Islands. The species grows to about 115 cm and has a very elongate, almost white body with a dark snout and dark markings on the head and shoulder. As a burrowing bottom-dweller it stays in sand and mud bottoms of shallow coastal water and emerges at night to hunt; the hard, pointed tail tip helps it burrow backwards. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
