Scientific Name : Rhinecanthus aculeatus Size : 30 cm Average Life Expectancy : 5 – 10 years

The triggerfish, which stand out with their shiny colors and eye-catching patterns, mostly live in tropical and subtropical waters. There are many species (about 40 species are known) of these gorgeous fish, which come in various sizes and colors and most of these species are seen in the Indo-Pacific Ocean. Triggerfish generally live in shallow waters like coral reefs. But some species (such as Canthidermis) also live in deep waters. Even though the size changes according to species, their average size is 20-50 cm. And their average weight is around 2.3 kilograms. They mostly eat seaweed, worms, mollusks, crustaceans, sea urchins, small fish, corals and fish eggs.

As a protection mechanism against predators, they have the ability to straighten the two rigid beams (spiked) on their backs. When the second beam is straightened the first also straightens. After the first beam has been straightened it can only return to its normal state after the second beam has gone down. This is where the name triggerfish comes from.
 

Where can it be seen?
