Triggerfish (Rhinecanthus) is one of the marine fish species that have a spur in front of the dorsal fin that can suddenly straighten up like the antenna of a ballista (the weapon).
This fish is very aggressive towards other fish.

Size: typical length of 35 cm
Weight: average 1.9 kg
Habitat and distribution: open ocean and coral reefs in the Indian and Pacific Oceans

The Triggerfish have this name because of their backbones. Many Triggerfish have extraordinary colors and spots as if painted by an artist.
The light Picasso triggerfish (Rhinecanthus aculeatus) lives on coral reefs and sandy seabeds.
It feeds on sea urchins, which it turns over by sending water to them to reach their prickle-free bellies.
