Dorsal Fin
• Large fin on back that varies in size, shape and position
• Stabilizes fish

Pectoral & Pelvic Fin
• Pectoral Fins: Located on side of body– Used for steering &

• Pelvic Fins: Located on belly or under pectoral fins– Function in stabilizing &
braking

• Anal Fin: Located on ventral side (underside) behind the pelvic fins
• Adipose Fin: Small fin located between the dorsal and caudal fin

Caudal Fin
• Caudal Fin: Tail fin that varies in shape, affecting the fish’s speed and buoyancy
• Used for propulsion

• Barbels: “Whiskers” near the mouth
• Used by bottom feeding fish to sense food
