I saw my first group of killer whales near Bird Island in Algoa Bay on the 20th Febtruary 1999. It was a group of four (three adults and a calf) spotted near a Bryde's Whale. they had captured a baby bottlenose dolphin and were "flicking" it to each other using their large flippers. The cries of the baby dolphin were quite unnerving but are one of the cruel things in nature that are necessary for a top predator's survival.
Killer whales are the largest member of the dolphin family. When any cetacean (group name forwhales, dolphins and porpoises) attains more than four metres it becomes known as a whale (withthe exception of the dwarf and pygmy sperm whales). Like many cetaceans these animals are knownby two names. The name Orca is derived from Orcus, the Roman god of the underworld whotortured wrongdoers in the afterlife. The term killer whale probably comes from the fact that theydo kill whales and were often seen feeding on dead whales during the days of whaling. These whalesare the top predators in the marine ecosystem.
