Detailed explanation-1: -Fins All fish have external appendages called fins. Like human limbs, fins provide fish with balance, steering, and protection. Fins are either single along the centerline of the fish: the dorsal fin, anal fin, and tail fin; or paired fins: the pectoral fins and ventral fins.

Detailed explanation-2: -Almost all fish have fins that they use for swimming (locomotion), balance, stability, and steering. A catfish has dorsal, adipose, caudal, anal, paired pelvic, and paired pectoral fins.

Detailed explanation-3: -Fish are vertebrates, meaning they have a backbone. All fish have fins and most have scales (with a few exceptions, like catfish which do not). Fish are cold blooded animals that lay eggs and are well suited for living in water. Learn about the different fish adaptations below that allow a fish to survive in water.

Detailed explanation-4: -Tail fin (Caudal fin) The tail fin (called the caudal fin) is the main source of movement for most fish. It’s like the motor on a boat. It shouldn’t be surprising then, that it is shaped differently according to how the fish needs to move most of the time. This helps the fish to move more efficiently through the water.
