Habitat

It lives mostly in sand and rubble areas in estuaries and coastal reefs.

Other behaviours and adaptations

When disturbed, the species often spreads its blue-margined pectoral fins. This behaviour is likely to startle potential predators.

Divers regularly see this species 'walking' along the bottom raised on the three detached lower rays of both pectoral fins.  Click on the link in rling's comment (17 August 2010) below to watch a short video.

Nice one Richard!

Great video, thank you for submitting it.  As you say, it really shows the fish 'walking' on its three lower pectoral fin rays.  I think the fish was very considerate splaying all its fins for you.  I have made a notation under the Behaviours heading above pointing users to your video.  Thanks again.
