There are 40 different species of triggerfish in the world native to the Eastern Pacific ocean. The larger one among the species has a length of 3.3 meters. Triggerfishes have strong, tough teeths help them to catch preys like crabs very easily. The oval shaped triggerfish have various colors in different parts of the body, make them so attractive. The color of triggerfish varies as blue, green and yellow.
Triggerfishes are about 40 species of often brightly colored fish of the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the aptly named oceanic triggerfish, are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.
The largest member of the family, the stone triggerfish reaches 1 m, but most species have a maximum length between 20 and 50 cm.
Triggerfish have an oval-shaped, highly compressed body. The head is large, terminating in a small but strong- jawed mouth with teeth adapted for crushing shells. The eyes are small, set far back from the mouth, at the top of the head. The anterior dorsal fin is reduced to a set of three spines. The first spine is stout and by far the longest. All three are normally retracted into a groove. The anal and posterior dorsal fins are capable of undulating from side to side to provide slow movement. The sickle-shaped caudal fin is used only to escape predators.
