Sperm whales are the largest of the toothed whales, reaching up to 20.5 metres. They often dive to 800 metres where they primarily feed on medium-sized squid, though they will also prey on the giant or colossal squid.
Killer whales are the largest members of the dolphin family, with males growing to 8 metres long. Resident killer whales in the Salish Sea feed primarily on salmon with their cone-shaped teeth. Transient killer whales feed on marine mammals like seals and sea lions.
Porpoises form a family of cetaceans, distinguished by their spade-shaped teeth and short beaks. Porpoises eat fishes, cephalopods, and some deep-sea organisms.
