Toothed whale does enamel show. Except for the sperm whale, most toothed whales are smaller than the baleen whales. The teeth differ considerably among the species. They may be numerous, with some dolphins bearing over 100 teeth in their jaws. At the other extreme are the narwhals with their single long tusks and the almost toothless beaked whales with tusk-like teeth only in males.Not all species are believed to use their teeth for feeding. For instance, the sperm whale likely uses its teeth for aggression and showmanship. Breathing involves expelling stale air from their one blowhole, forming an upward, steamy spout, followed
Ginkgo-toothed beaked whale pelagic longline fishery in the central and western Pacific Ocean. in The ginkgo-toothed beaked whale is covered by the Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MOU). Ginkgo-toothed beaked whale The ginkgo-toothed beaked whale ("Mesoplodon ginkgodens") is a poorly known species of whale even for a beaked whale, and was named for the unusual shape of its dual teeth. It is a fairly typical-looking species, but is notable for the males not having any scarring. Ginkgo-toothed beaked whales are more robust than most mesoplodonts, but otherwise look fairly typical.
