Trunkfish are small, marine fish belonging to the family Ostraciidae. They are known for their unique, boxy shape and hard, bony shells that provide protection from predators. These fish typically inhabit shallow waters in tropical and subtropical regions, often found around coral reefs and seagrass beds. Trunkfish have a distinctive appearance, with a pattern of spots or stripes that can vary by species. They primarily feed on small invertebrates, such as crustaceans and mollusks. Their slow swimming style and ability to blend into their surroundings help them avoid detection by larger fish.
