List Of Mammals Of Tokelau
This is a list of the mammal species recorded in Tokelau. There are five mammal species in the waters off Tokelau, all of which are of the order Cetacea. Order: Cetacea (whales) The order Cetacea includes whales, dolphins and porpoises. They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater. *Suborder: Odontoceti **Family: Physeteridae ***Genus: ''Physeter'' **** Sperm whale, ''Physeter macrocephalus'' VU **Superfamily: Platanistoidea ***Family: Ziphidae ****Subfamily: Hyperoodontinae *****Genus: '' Mesoplodon'' ****** Blainville's beaked whale, ''Mesoplodon densirostris'' DD ****** Ginkgo-toothed beaked whale, ''Mesoplodon ginkgodens'' DD ***Family: Delphinidae (marine dolphins) ****Genus: ''Stenella'' ***** Spinner dolphin, ''Stenella longirostris'' LR/cd ****Genus: '' Feresa'' ***** Pygmy killer whale, ''Feresa attenuat ...

Tokelau
Tokelau (; ; known previously as the Union Islands, and, until 1976, known officially as the Tokelau Islands) is a dependent territory of New Zealand in the southern Pacific Ocean. It consists of three tropical coral atolls: Atafu, Nukunonu, and Fakaofo. They have a combined land area of . The capital rotates yearly among the three atolls. In addition to these three, Swains Island, which forms part of the same archipelago, is the subject of an ongoing territorial dispute; it is currently administered by the United States as part of American Samoa. Tokelau lies north of the Samoan Islands, east of Tuvalu, south of the Phoenix Islands, southwest of the more distant Line Islands, and northwest of the Cook Islands. Tokelau has a population of approximately 1,500 people; it has the fourth-smallest population of any sovereign state or dependency in the world. As of the 2016 census, around 45% of its residents had been born overseas, mostly in Samoa or New Zealand. The populace has ...

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. Description Ginkgo-toothed beaked whales are more robust than most mesoplodonts, but otherwise look fairly typical. Halfway through the jaw, there is a sharp curve up where the ginkgo leaf-shaped tooth is. Unlike other species such as Blainville's beaked whale and Andrews' beaked whale, the teeth do not arch over the rostrum. The beak itself is of a moderate length. The coloration is overall dark gray on males with light patches on the front half of the beak and around the head, and small white spots on the bottom of the tail, but the location may be variable. Females are a lighter gray and have countershading. Both genders reach in length. They are around long when born. Population and distribution This beaked w ...

Mammals Of New Zealand
Prior to human settlement, the mammals of New Zealand consisted entirely of several species of bat, and several dozen marine mammal species. Far earlier, during the Miocene, at least one "archaic" terrestrial mammal species is known to have existed, the Saint Bathans mammal. The Māori brought the ''kurī'' (Polynesian Dog) and ''kiore'' (Polynesian rat) in about 1250 CE, and Europeans from 1769 onwards brought the pig, mice, two additional species of rats, weasels, stoats, ferrets and possums and many other species, some of which cause conservation problems for indigenous species. Indigenous species * Three recent species of bats: the long-tailed, short-tailed and lesser short-tailed. Though they varied in range, Holocene fossils of all three species have been found near Cape Reinga / Te Rerenga Wairua at the far north of the North Island. The Miocene Saint Bathans Fauna showcases a considerably higher diversity of at least four mystacine species, a vesper bat and several '' ...

List Of Mammals Described In The 2000s
Although the mammals are well studied in comparison to other animal groups, a number of new species are still being discovered. This list includes extant mammal species discovered, formally named, or brought to public light in the year 2000 or later. Notable subspecies are also included, as are mammals rediscovered after being declared, or seriously suspected to be, extinct. Newly discovered fossils are not included. Marsupials At least five new species of marsupials have been discovered since 2000: * The delta opossum (''Philander deltae''); * The Mondolfi's four-eyed opossum (''Philander mondolfii''); * The Arfak pygmy bandicoot (''Microperoryctes aplini''); * The short-eared possum (''Trichosurus caninus''); * The red-bellied gracile opossum (''Cryptonanus ignitus''). Elephants In 2001, genetic evidence emerged that the African elephant (''Loxodonta africana''), once thought to be a single species, was in fact two, as the smaller African forest elephant was in fact ...

Mammal Classification
Mammalia is a class of animal within the phylum Chordata. Mammal classification has been through several iterations since Carl Linnaeus initially defined the class. No classification system is universally accepted; McKenna & Bell (1997) and Wilson & Reader (2005) provide useful recent compendiums. Many earlier ideas from Linnaeus et al. have been completely abandoned by modern taxonomists, among these are the idea that bats are related to birds or that humans represent a group outside of other living things. Competing ideas about the relationships of mammal orders do persist and are currently in development. Most significantly in recent years, cladistic thinking has led to an effort to ensure that all taxonomic designations represent monophyletic groups. The field has also seen a recent surge in interest and modification due to the results of molecular phylogenetics. George Gaylord Simpson's classic "Principles of Classification and a Classification of Mammals" ( Simpson, 1945) ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pygmy Killer Whale
The pygmy killer whale (''Feresa attenuata'') is a poorly known and rarely seen oceanic dolphin. It is the only species in the genus ''Feresa''. It derives its common name from sharing some physical characteristics with the orca also known as the killer whale. It is the smallest cetacean species that has the word "whale" in its common name.Masa Ushioda“Pygmy Killer Whale” ”Cool Water Photo”, March 11, 2015 Although the species has been known to be extremely aggressive in captivity, this aggressive behavior has not been observed in the wild. The species had been described by John Gray in 1874, based on two skulls identified in 1827 and 1874. The next recorded sighting was in 1952 which led to its formal naming by Japanese cetologist Munesato Yamada in 1954. Description Distinguishing features The pygmy killer whale is dark gray to black on the cape and has a sharp change to lighter gray on the sides.
