A few toothed whale species may only have a small handful of teeth that appear to be fairly useless when it comes to their survival. In the past, whalers have sought out the Sperm whale for the valuable spermaceti oil, which makes an extremely fine lubricant. DNA evidence suggests it separated from oceanic dolphins about 25 million years ago. Sperm whales have large, square heads and 20-26 conical teeth on each side of its lower jaw.

The largest of the toothed whales is the sperm whale, one of the few whale species that can live in a range of environments and is therefore found in oceans across the world. They include species as small as the vaquita and as large as the sperm whale, and exhibit diverse characteristics, distribution, and feeding strategies. Speciation in the Platanistoidea, systematic, zoogeographical and ecological observations on recent species. Living in temperate waters, the Spade-toothed whales may be threatened by climate change, causing ocean warming, which in turn leads to reduction and modification of their natural range. [1] Historically, cetaceans were thought to have descended from the wolf-like mesonychids, but cladistic analyses confirm their placement with even-toed ungulates in the order Cetartiodactyla. Oceanic dolphins are the members of the family Delphinidae. Males can weigh up to 56 tons. The Bryde’s Whale ranges in size depending on where they are located.

Recent preliminary research indicates that baleen and toothed whales, such as narwhals and belugas, could be susceptible to the new coronavirus that causes COVID-19. A second major difference between the two species is the use of and reliance on echolocation. Pilot whales -- small, toothed whales with a bulging forehead, a short snout and pointed flippers -- are sociable creatures, and live in groups of dozens, hundreds or even thousands. It belongs to the killer whale or orca (Orcinus orca), a toothed whale of the oceanic dolphin family.

The toothed whales form an extraordinary group of marine mammals, ranging in size over several orders of magnitude from the smallest harbour porpoises in the Black Sea (1.3 m long and 45 kg) to the cosmo-politan sperm whale (18 m long, 57,000 kg). The Dwarf Sperm Whale is the smallest whale. In tabular form, seven descriptors are given for each species: the common name; the scientific name; the IUCN Red List status; a global population estimate; a global map with its range; its weight with an image of its shape, and its size relative to a human; and a photograph. There are 150,000 individuals in the eastern tropical Pacific Ocean. Baleen whales are characterized by having baleen plates for filter feeding and two blowholes.
