Triggerfish

The Balistidae family of fish includes a sizable number of brilliantly colored fish, including the triggerfish. A few, like the oceanic triggerfish (Canthidermis maculata), are pelagic, but the majority are found in relatively shallow, coastal settings, particularly on coral reefs. Even though a few members of this family are common in marine aquarium commerce, they are frequently renowned for having bad tempers. When defending their eggs, certain triggerfish species can become highly combative. When a diver encounters an angry triggerfish, it is preferable to swim horizontally away from the nest site since their domain spreads in a cone shape from the nest toward the surface. Swimming upwards can place a diver more into the fishes' territory. In contrast to the Picasso triggerfish, which is relatively tiny, the titan triggerfish is much larger and has more powerful teeth, which makes it a major hazard to careless divers.

An aggressive predatory fish is the triggerfish. They are also thought to be more intelligent than fish and capable of learning from past errors. In addition to this, they have a robust jaw and teeth that are specially designed to break through hard shells.

One of the frequent predators of sea urchins and other comparable bottom-dwelling marine creatures is the triggerfish. A triggerfish may readily surpass the sea urchin's defenses due to its extreme aggression. They can each take out a few of the sea urchin's protective spines before they can bite right into its body.
