These cetaceans are mammals that live in the water
Whales, dolphins and porpoises all live in water, but they’re not fish. They’re water-dwelling mammals known as cetaceans (Seh-TAY-shuns). This group includes the largest animals on Earth — blue whales — which can grow up to 29.9 meters (98 feet) in length. Most cetaceans live in the ocean, but there are a few species that live in freshwater or brackish water (water that is salty, but not as salty as the ocean). Cetaceans don’t have gills as fish do. To get the oxygen they need, these mammals breathe in air through structures called blowholes.
Cetaceans are split into two groups based on what and how they eat. Toothed whales — such as sperm whales, orcas (killer whales), dolphins, narwhals and porpoises — all have teeth that help them catch prey. They eat fish, squid and other large critters. Orcas have been known to eat penguins, seals, sharks and other whales. Most species of toothed whales can use echolocation to find prey.
Baleen whales lack teeth. Instead, plates of baleen line their mouths. That baleen is made of keratin — the same stuff as hair — and lets the whale filter krill and other small invertebrates from the water to eat. Humpback whales in Alaska, though, have figured out they can get a free meal of tiny salmon by hanging out at fish hatcheries.
