Canthigaster

The genus Canthigaster refers to a group of small, brightly colored fish, typically no more than 20 centimeters long. These fish are characterized by their long, pointed snouts and inconspicuous nostrils. They are found in seas worldwide and are related to puffers. Unlike puffers, Canthigaster species do not have fused teeth forming a beak-like structure. Some species are kept in marine aquariums.1

The family Tetraodontidae, commonly known as puffers, includes about 90 species of fish found in warm and temperate waters globally. These fish are known for their ability to inflate themselves with air or water when disturbed, becoming globular in shape. They possess tough, often prickly skin and fused teeth that form a beak. Many puffer species are poisonous due to a toxin called tetraodontoxin, concentrated in their internal organs, which can be fatal. Despite this, some puffers, like the Japanese fugu, are consumed after careful preparation by trained chefs.1
