PLEASE MARK ME AS BRAINLIEST
a. Dorsal fin- The dorsal fins increase the lateral surface of the body during swimming, and thereby provide stability but at the expense of increasing drag.
b. Caudal fin- The caudal fin is the tail fin (from the Latin cauda meaning tail), located at the end of the caudal peduncle and is used for propulsion.
c. Anal fin- The anal/cloacal fin is located on the ventral surface behind the anus/cloaca. This fin is used to stabilize the fish while swimming. The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin.
d. Pelvic fin- Pelvic fins, located on the bottom of the fish in front of the anal fin, help balance the fish, keep it level, and prevent it from rolling from side to side. Fish sometimes rest by sitting on their pelvic fins.
