An overview of the scientific order of whales cetacea
Definition: a scientific order of various aquatic, chiefly marine mammals, including whales, dolphins and porpoises, characterized by a nearly hairless body, anterior limbs modified into broad flippers, vestigial posterior limbs, and a flat, notched tail. The national marine mammal laboratory (nmml) conducts research on marine mammals important to the mission of the national marine fisheries service (nmfs) and the national oceanic & atmospheric administration (noaa), with particular attention to issues related to marine mammals off the coasts of alaska, washington, oregon, and california. In the 1980s, the minke whale became the most heavily hunted baleen whale, after the other whale populations were over-exploited in 1994, after intense pressure from japan, norway, and denmark, the international whaling commission gave permission for this whale to be hunted for scientific purposes. The word cetacean is derived from the latin cetacea, the scientific name for the order of marine mammals that comprises whales, dolphins and porpoises two suborders of cetacea exist today: mysticeti , or baleen whales, are characterised by having baleen plates for filtering food from the water, rather than teeth.
The order cetacea comprises some amazing species, representing some of the most evolved creatures that inhabit this earth yet, they also represent a group of species for which much remains unknown there are over 80 species of cetaceans composed of porpoises, dolphins and whales. Classification kingdom-animalia (animals) phylum-chordata (vertebrates) class-mammalia (mammals) order-cetacea (whales, dolphins and porpoises) suborder-mysticeti (baleen whales) family-balaenopteridae genus-megaptera species-novaeangliae phylogenetic tree illustrating the evolution of marine mammals. The scientific suborder’s name, mysticeti, most likely derived from the greek word, mystakos, meaning moustache, possibly referring to the baleen plates attached to the whale’s upper jaw.
Sperm whales are the largest of the toothed whales and have one of the widest global distributions of any marine mammal species they are found in all deep oceans, from the equator to the edge of the pack ice in the arctic and antarctic. Beluga whales are among the smallest species of whales adult males range from 13 to 20 feet (4 to 61 meters) in length and weigh 2,000 to 3,000 lbs (907 to 1,361 kilograms), according to. This is a list of cetaceans the order cetacea includes whales, dolphins, and porpoises it has 88 living species, divided into the suborders odontoceti (the toothed whales, including dolphins and porpoises) and mysticeti (the baleen whales) in addition, numerous species of extinct cetaceans. Whales, dolphins, and porpoises are all members of the scientific order cetacea they are divided into three suborders: 1) archaeoceti (extinct whales. The order cetacea comprises two extant sub-orders and one extinct sub-order the extant sub-orders are mysticeti (baleen whales) and odontoceti (toothed whales) both mysticetes and odontocetes are thought to be descendants of archaeocetes (archaeoceti, ancient whales), an extinct sub-orderthere are at least 83 living species of cetaceans, with 46 genera in 14 families.
Whales, dolphins, and porpoises, edited by whale biologist berta, explains the diet, conservation status, and a host of other details for each of the 89 species of cetacea this guide is a fantastic resource for biologists and aquatic-mammal watchers alike. Whales are members of the order cetacea, along with dolphins, porpoises, and the narwhal there are two basic types of living cetaceans: baleen, or whalebone, whales of the scientific suborder mysticeti and toothed whales of the suborder odontoceti. Taxonomy taxonomy is the science of classifying organisms into groups by structure, origin, common ancestor, etc one goal is to recognize the inherent order in nature. The scientific order cetacea includes all whales and dolphins this order is so great that it is also divided into three sub-groups: the toothed whales or odontoceti (killer whale, dolphins, porpoises, belugas and the sperm whale. Whale, any of the larger species of aquatic mammals belonging to the order cetacea the term whale can be used in reference to any cetacean, including porpoises and dolphins , but in general it is applied to those more than 3 metres (10 feet) long.
An overview of the scientific order of whales cetacea
The order cetacea comprises two extant sub-orders and one extinct sub-order the extant sub-orders are mysticeti (baleen whales) and odontoceti (toothed whales) both mysticetes and odontocetes are thought to be descendants of archaeocetes ( archaeoceti , ancient whales), an extinct sub-order. There are about 86 species of whales, dolphins and porpoises in the order cetacea, which is further divided into two sub-orders, the odontocetes, or toothed whales and the mysticetes, or baleen whales. Cetacea an order of marine mammals comprising the whales, which includes what is probably the largest known animal – the blue whale (balaenoptera musculus), over 30 m long and over 150 tonnes in weight the forelimbs of whales are modified as short stabilizing flippers and the skin is very thin and almost hairless. The order cetacea are marine mammals that live in oceans, seas, and even a few rivers around the world whales, dolphins, and porpoises are part of this group these common name refer to size: whales are the largest, porpoises the smallest how and what they eat is a better guide to their relationships.

- Dolphins, porpoises and whales are included in the order cetacea they are mammals fully adapted to marine life and are divided into two suborders, mysticet (baleen whales: including blue, humpback, gray, bowhead, minke and right whales) and odontoceti (toothed whales: including killer whales or orcas, beluga whales, narwhales, sperm whales, dolphins and porpoises.
Cetacea is a scientific order of large aquatic mammals that have forelimbs modified into flippers, a horizontally flattened tail, one or two nostrils at the top of the head for breathing, and no hind limbs. Overview of whale species classification of the sperm whales the sperm whales are currently classified as toothed whales, but there is a growing body of evidence that they are actually closer to the baleen whales than to the toothed whales. Cetacea (/ s ɪ ˈ t eɪ ʃ ə /) is a widely distributed and diverse clade of aquatic mammals that today consists of whales, dolphins, and porpoisescetaceans are carnivorous and finned most species live in the sea, some in rivers the name is derived from the latin cetus whale, itself from the greek κῆτος kētos huge fish there are around 89 extant species, which are divided. The cetacea are one of the most distinctive and highly specialized orders of mammalsthey include the largest animal that has ever lived, the blue whale the highly intelligent and communicative dolphins the tusked narwhals and blind river dolphins and singing humpback whales — nearly eighty living species in all.
