Acanthuridae
Acanthuridae is a family of marine fish commonly known as surgeonfish or tangs. They are characterized by their oval-shaped bodies, vibrant colors, and sharp spines near their tails. These fish are found in tropical and subtropical waters around the world and are known for their distinctive scalpel-like appendage on their tails, which gives them their name. Acanthuridae species play important roles in coral reef ecosystems as grazers, helping to control algae growth and maintain the health of the reef.
