They have paddle-shaped pectoral fins, and a distinct dorsal fin (curved in females and immature males; straight and up to about six feet tall in males). The male orca's dorsal fin reaches its full height at age 15-25 years.

The Lowdown on Dorsal Fins All killer whales have a dorsal fin on their back, but the male's dorsal fin is much taller than a female's and can grow up to 6 feet tall. 1  Despite the fact that the dorsal fin is very straight, it is supported not by bone but a fibrous connective tissue called collagen.
