False Killer Whale
They have a rounded head and no beak. They are fully black or gray on the upperside and have white stripes on the underside.
They are curious around boats and generally seen in deeper waters.
Tropical and warmer-temperate oceans worldwide
They move from warmer, southern waters in winter to cooler, northern waters in summer. The population around Hawaii shows strong site fidelity.
Social system/Group size
Most commonly seen in groups of 10 - 20 with about equal numbers of males and females. Long-term bonds have been documented in Hawaii.
They are hunted for food and killed to reduce competition for fisheries. Pollution and noise may have led to several mass strandings.
Despite the name "false killer whale", is not closely related to the orca.
