Which body part do fishes use for maneuvering in water?

Fins are the primary body parts that fish use for manoeuvring in water. Different types of fins serve distinct functions:

• Pectoral fins (paired, on the sides behind the gills) control steering, braking, and hovering.
• Pelvic fins (paired, on the underside) help with stability and turning.
• Dorsal fin (on the back) prevents rolling and aids stability.
• Anal fin (on the underside near the tail) also assists with stability.
• Caudal (tail) fin provides the main thrust for forward movement.

The lateral line is a sensory organ that runs along each side of the fish's body. It detects vibrations and pressure changes in the surrounding water, helping the fish sense nearby objects and movements, but it does not propel or steer the fish. Barbels are tactile and taste-sensing organs found on some fish species (such as catfish) and are used to locate food, not for movement. The spine (vertebral column) provides structural support for the body but is not directly responsible for manoeuvring.
