Killer whales, or orcas, are very well known due to their unique markings and ominous name. These mammals are part of the dolphin family. They spy hop, breach, lobtail and slap their pectoral fins. They are often encountered in pods or sub-pods that can vary from a few individuals to more than 30 members. There are several races of orcas, "residents" which feed on fish, "transients" that feed on other marine mammals, and "offshores" of which little is known.
