Distribution and habitat preferences

While this species is sometimes seen in quite shallow water, it is more common in water deeper than about 10 metres on sand or a mixture or rubble and sand. It occurs at the outer barrier reefs as well as other mid-shelf reefs near Lizard Island.

Behaviour

Spawning has been observed in April and in November in the Lizard Island area. Individuals raise the front half of the body into an upright position and eject spawn from a gonopore on top of the head.
