Orcas (formerly known as killer whales), Orcinus orca, are actually dolphins. They are the largest of the dolphin family (Family Delphinidae with about 32 species, including the dolphins, pygmy killer whales, Feresa attenuata, and false killer whales, Pseudorca crassiddens). Next to humans, orca are the most widely distributed mammal. Orca inhabit all oceans of the world but are most numerous in the Arctic, the Antarctic and areas in nutrient-rich cold water upwellings. They have been sighted along the shores of Washington, Oregon, California, Baja California, and along the eastern coast of the United States.
Why We Need Marine Reserves Ninety percent of the large predators in the ocean are gone and their populations have collapsed. The reason for this is that we have taken too many fish out of the sea, and we keep taking more before the remaining populations are able to reproduce. Watch this video where Mel, the “very weird” fish, will show you how marine reserves can help fish populations recover, and why we need many more. Learn More
