Reef triggerfish

The reef triggerfish is reminiscent of abstract art.  We see them often, but they don't hang around long.  Rather, they go swimming by.  The Hawaiian name for this fish is humuhumu nukunuku apua'a.  This is the fish that is mentioned in the "My Little Grass Shack" song from 50 or 60 years ago.  They grow up to 10 inches long.
