description False Killer Whale Overview
The false killer whale (Pseudorca crassidens) is a large species of oceanic dolphin named for its visual resemblance to the true killer whale (orca). It exhibits a dark gray or black coloration and possesses a conical head without a prominent beak. This species is highly social and typically lives in large groups, or pods, that travel through deep oceanic and tropical waters worldwide. It is known for its mass stranding events, a phenomenon where large numbers of individuals will beach themselves simultaneously.
help False Killer Whale FAQ
Is a false killer whale actually a whale or a dolphin?
Pseudorca crassidens belongs to Delphinidae, the oceanic dolphin family. Like the orca, it is called a whale because it is one of the family's largest members.
How can you tell a false killer whale from an orca?
False killer whales are mostly dark gray or black, with a slender body, a small conical head, and no orca-like white eye patch. Adult males can approach 20 feet, but they remain slimmer and less boldly patterned than Orcinus orca.
What do false killer whales eat?
They are top predators that primarily hunt large fish and squid. NOAA has documented individuals converging on captured prey and sharing food with other members of their social group.
Why are false killer whales endangered around Hawaii?
The main Hawaiian Islands insular population is listed under the U.S. Endangered Species Act and numbers fewer than 200 animals. Threats include interactions with longline fisheries, low population size, contaminants, and reduced prey availability.
