Acanthuridae are a family of marine fish commonly known as surgeonfish, tangs, or unicornfish. They are characterized by a pair of spines located on either side of the caudal peduncle, which are used for defense. They have a laterally compressed body shape and a single dorsal fin. Acanthuridae inhabit tropical and subtropical waters, and their lifespan is typically between 5 and 10 years. The current population of Acanthuridae is stable.
Name Origin: The Acanthuridae family of fish, commonly known as surgeonfish, is named for the sharp spines located on either side of their caudal peduncle, which resemble a surgeon's scalpel. These spines are used for defense and to establish dominance within the species.
