The average size of a Picasso triggerfish is about 9 to 10 inches. This fish is usually found by the islands of Tuamoto, Hawaii, and Marquesas Islands. The Picasso triggerfish mostly eats on crustaceans such as crabs, worms, sea urchins, shrimp and a few other small invertebrates. They also eat algae, corals, detritus and eggs. They get their food by going through sand and rocks. The triggerfish is named for its flexible trigger spines, which are used for when they are hiding so nothing can get them out of a rock. Most triggerfish have a pattern of spots and lines and are usually brightly colored. The population of the Picasso triggerfish is currently unknown.
