Acanthuridae
Acanthuridae, also known as surgeonfishes or tangs, is a family of marine fish characterized by a scalpel-like spine on each side of the tail base. They are found in warm waters around the world, particularly in coral reef environments. Surgeonfishes have elongated bodies and are generally brightly colored, making them popular among aquarium hobbyists. They feed primarily on algae, using their beak-like mouths to scrape it off of rocks and other surfaces. Acanthuridae is a subgroup within the larger category of Saltwater Fish, which includes all fish that inhabit marine environments. These fish can be further classified as Fish, which refers to any gill-bearing aquatic craniate animal with fins and typically a streamlined body. Acanthuridae fits into the broader hierarchy of Animals/Animals By Taxonomy, which encompasses all organisms that are classified based on their biological characteristics.
