Boxfish are small, marine fish known for their unique, box-like shape and hard, bony exterior. They belong to the family Ostraciidae and are typically found in warm, shallow waters of the Atlantic, Indian, and Pacific Oceans. Their distinctive appearance helps them blend into coral reefs and avoid predators. These fish are usually brightly colored, with patterns that can vary significantly between species. Boxfish primarily feed on algae, small invertebrates, and plankton. They are also known for their slow swimming style and can release toxins when threatened, which serves as a defense mechanism against predators.
