# Really, Killer! Whales (DD-192)

> The orca, or killer whale (Orcinus orca), is the largest member of the dolphin family. Many populations live in matrilineal groups in which offspring stay with their mothers, and older females, including post-reproductive grandmothers, lead the group and help it find food. Pods cooperate to hunt, sometimes using techniques passed on within the group. Orca pods have distinct vocal dialects, sets of calls shared within a group and different from other groups'. The footage shows orca pods hunting and swimming, with the presenter.
