Description
The Paletail Unicornfish is a very large marine fish characterized by a prominent horn-like projection on its forehead, which becomes more pronounced with age. It typically exhibits a brownish-grey body and a distinctive pale or white caudal fin, often with a dark band at its base. This species is primarily an herbivore, grazing on benthic algae in its natural coral reef environment.
