In the Pacific, a census recorded 175,000 individuals in eastern tropical waters and 85,000 in the west. 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). Aristotle, however, could already see many physiological and anatomical similarities with the terrestrial vertebrates, such as blood (circulation), lungs, uterus, and fin anatomy. Cetaceans are descended from land-dwelling hoofed mammals, and the now extinct archaeocetes represent the several transitional phases from terrestrial to completely aquatic. [10], The family Balaenidae, the right whales, contains two genera and four species. 11-18 metres in length (females are smaller than males). Browsing Category.

There are Baleen Whales and Toothed Whales. Toothed whales include orcas and other dolphins, sperm whales and pilot whales. The order Cetacea comprises the sea mammals commonly known as whales, dolphins and porpoises, and is divided into two extant sub-orders: Odontoceti (toothed whales) and Mysticeti (baleen whales). It belongs to the killer whale or orca (Orcinus orca), a toothed whale of the oceanic dolphin family. They also have a gestation period of over a year, which is unusual for baleen whales.

The Society for Marine Mammalogy has created an extensive list of cetacean species (see below). Success! Dwarf sperm whales have a stocky appearance that narrows down the … "Phylogenetic relationships of artiodactyls and cetaceans as deduced from the comparison of cytochrome b and 12S RNA mitochondrial sequences", "Relationships of Cetacea -Artiodactyla- Among Mammals: Increased Taxon Sampling Alters Interpretations of Key Fossils and Character Evolution", "The IUCN Red List of Threatened Species", "The Ultimate Mouthful: Lunge Feeding in Rorqual Whales", "List of Marine Mammal Species and Subspecies", "What's the difference between dolphins and porpoises?

D&D Beyond [7] Smaller cetaceans are at risk of accidentally getting caught by fishing vessels using, namely, seine fishing, drift netting, or gill netting operations.[8]. It is divided into toothed whales (Odontoceti) and baleen whales (Mysticeti), which diverged from each other some time in the Eocene 26 to 17 million years ago (mya). It is closely related to the slightly larger Pygmy Sperm Whale, which is also found in Antarctic waters.Both species are most often seen floating motionless at the surface; this behaviour is known as ‘logging’.These rare whales are seldom seen. It is the only benthic feeding baleen whale, filtering small organisms from the mud of shallow seas. Southern Resident Killer Whale.
