Dorsal fin: Rounded over tip, usually lacks the sharper angle at the rear corner. Sounds: Distinct calls from transients and residents. Frequently vocal, use lots of echolocation. Distribution: Far from coastline along continental shelf. Estimated range is from Southern California to the Aleutian Islands. Sign up for our newsletter. Killer whale - biology fast facts. Body size: Adult female up to approximately 8m; weighs up to 7, kg; dorsal fin up to 1m Adult male up to approximately 10m; weighs up to 10, kg; dorsal fin up to 2m Newborn calf up to 2.
Vocal Behavior: Killer whales produce three types of vocalizations: echolocation clicks are used for orientation and to find prey, whistles appear to function in short-range communication, and pulsed calls are highly stereotyped and likely function in long range communication.
Physical Characteristics : Orcas are distinctively coloured. Travel Speeds: Killer whales are one of the fastest marine mammals in the sea. Social structure: Live in a matriarchal society: male and female offspring remain with their mother as long as she is alive Average group size: whales. Both species have trouble maintaining such speeds over long distances, and will swim this quickly only when in hot pursuit of prey or fleeing from danger.
Orcas are natural predators of dolphins, so the dolphin's slight lead can be a significant advantage in moments of escape. While many theories abound about the dolphin's ability to reach such breakneck speeds, Jim Rohr of the U. Navy's Space and Naval Warfare Systems Center says that much of the reason is that dolphins' bodies are "incredibly streamlined.
Orcas' bodies have a fusiform shape—this means the animal is wide in the middle but tapered at each end, which helps the orca cut through the water despite his large size. Under an orca's hairless skin is a layer of blubber, which contributes to the whale's smooth shape. Orcas also use a swimming technique known as "porpoising," in which they swim just below the water's surface, then quickly rise up above it and back down in one quick move.
This technique helps the orcas preserve energy, since porpoising requires less effort than maintaining speed at one depth just below the surface. Another trick orcas use is to hitch a ride on waves or the wake created by boats, which helps them achieve twice their normal speed without exerting any extra energy.
