Rhinecanthus assasi, commonly known as the Red Sea Picasso triggerfish or Arabian Picasso triggerfish, is a species of triggerfish belonging to the family Balistidae. Here are some key characteristics and information about this species:
- Distribution: Picasso triggerfish are found in the Indo-Pacific region, particularly in the Red Sea and the Arabian Gulf. They inhabit coral reefs and lagoons with rocky or sandy bottoms.
- Appearance: This species is known for its distinctive and colorful pattern. It has a grayish to bluish body adorned with bold, dark lines and markings that resemble abstract art, hence the name “Picasso.” The face typically has yellowish or orange markings around the eyes and mouth. Like other triggerfish, it has a robust body with a dorsal spine that can be locked into place for defense.
- Size: They can grow up to about 30 cm (12 inches) in length.
- Behavior: Picasso triggerfish are known to be territorial and can be aggressive towards other fish, especially conspecifics or similar-sized species. They feed primarily on a diet of small crustaceans, mollusks, and other invertebrates, using their strong jaws and teeth to crush shells and hard-bodied prey.
