Assasi (Egyptian Picasso) Triggerfish

Description:

Distinct pattern varies from the usual picasso pattern, lacking the diagonal stripes in front of the tail Picasso's dig their shelters under solid objects by swimming sand away. This is done by putting their mouth against a solid object and swim like crazy, thereby creating a current that takes the sand away and making a little nest area.

Habitat:

Drop off by an inshore reef.

Notes:

Triggerfish have a hard spine Dorsal Fin that can be locked. When sleeping this spine is used to wedge them into place in a crevasse and so deter predators from pulling them out of their bed! The spine is also held erect as a warning to other fish to stay away.
