its heart weighs about 180 kilograms and on a dive can beat as slowly as two beats a minute, a study reported. - [7](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/7/) — Baleen is a curtain of hundreds of plates on each side of the upper jaw, made of keratin like fingernails; it sieves krill and small fish out of the water. - [8](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/8/) — The fin whale is the second biggest animal, about 20 to 25 metres long, and so fast it is called the greyhound of the sea; its lower jaw is white on the right side and dark on the left. - [9](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/9/) — Humpbacks blow a spiral net of bubbles around a shoal of fish and then swim up through the middle with mouths open; often several work together. - [10](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/10/) — Humpbacks have the longest flippers of any whale, about a third of their body length, with a row of bumps on the front edge that helps them turn tightly; engineers have copied the bumps for fan and turbine blades. - [11](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/11/) — Grey whales swim about 16,000 to 20,000 kilometres there and back each year, feeding in the Arctic in summer and having babies in warm lagoons in Mexico in winter. - [12](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/12/) — Grey whales feed by sucking mud from the seabed and sifting out small creatures; in Mexican lagoons some now come up to boats and let people touch them, though whalers once called them devil fish. - [13](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/13/) — Right whales have rough white patches on their heads covered in tiny whale lice; the pattern differs on each whale, so scientists recognise each one, and only about 370 North Atlantic right whales were left, reported. - [14](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/14/) — The minke is the smallest of the big baleen whales, about 7 to 10 metres long, and is the whale most often seen near boats around Britain in summer. - [15](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/15/) — Baleen whales have two blowholes and toothed whales have one; blowholes are nostrils that moved to the top of the head over millions of years. - [17](https://md.mova.elamur.ai/free/en/corpora/school/biology/312-whales-by-kind-the-baleen-whales-blue-fin-humpback-grey-right-and-minke/17/) — Whales dive to eat and come up to poo, and their poo, rich in iron, feeds tiny floating plants near the surface, which feed krill; so more whales can mean more krill, not less. - ← previous: [Sharks by kind, small and strange: walking sharks, wobbegongs, cookiecutters and goblin sharks](https://md.mova.elamur.ai/free/en/corpora/school/biology/311-sharks-by-kind-small-and-strange-walking-sharks-wobbegongs-cookiecutters-and-goblin-sharks/) - next →: [Whales by kind, the toothed whales: sperm whale, orca, beluga and beaked whales](https://md.mova.elamur.ai/free/en/corpora/school/biology/313-whales-by-kind-the-toothed-whales-sperm-whale-orca-beluga-and-beaked-whales/) - ↑ back to [Biology](https://md.mova.elamur.ai/free/en/corpora/school/biology/)
