List Of Mammals Of Christmas Island
This is a list of the mammal species recorded on Christmas Island. The island had five native and endemic land mammal species, of which three are now presumed to be extinct.John Woinarsk"Australian endangered species: Christmas Island Shrew" ''The Conversation'', 9 May 2013. Retrieved January 21, 2015. In addition, five wild mammals have been introduced to Christmas Island since settlement. Carnivora Introduced cats and dogs are a threat to native wildlife on Christmas Island and can carry potentially dangerous pathogens, such as ''Leptospira''. In 2014, the Australian Government announced a $500,000 investment to help eradicate stray and feral cats on the island, with the aim of complete eradication by 2020. As of 2016, all pet cats on Christmas Island have been registered and de-sexed and no further cats will be permitted onto the island. Chiroptera Christmas Island was once home to two native bat species, of which only one is extant. The Christmas Island pipistrelle was end ...

Christmas Island
Christmas Island, officially the Territory of Christmas Island, is an Australian external territory comprising the island of the same name. It is located in the Indian Ocean, around south of Java and Sumatra and around north-west of the closest point on the Australian mainland. It lies northwest of Perth and south of Singapore. It has an area of . Christmas Island had a population of 1,692 residents , the majority living in settlements on the northern edge of the island. The main settlement is Flying Fish Cove. Historically, Asian Australians of Chinese, Malay, and Indian descent formed the majority of the population. Today, around two-thirds of the island's population is estimated to have Straits Chinese origin (though just 22.2% of the population declared a Chinese ancestry in 2021), with significant numbers of Malays and European Australians and smaller numbers of Straits Indians and Eurasians. Several languages are in use, including English, Malay, and various ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vespertilionidae
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus ''Vespertilio'', which takes its name from a word for bat, ', derived from the Latin term ' meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds". (The term "evening bat" also often refers more specifically to one of the species, '' Nycticeius humer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A typical adult black rat is long, n ...

Maclear's Rat
Maclear's rat (''Rattus macleari'') is an extinct large rat endemic to Christmas Island in the Indian Ocean. It was one of two species of rat native to Christmas Island, alongside the bulldog rat. Abundant, unfamiliar with and seemingly unafraid of humans, large numbers of the creatures emerged and foraged in all directions at night. Making querulous squeaks, the rats entered the ''Challenger'' expedition's tents and shelters in 1886, ran over sleepers, and upset everything in the search and fight for food. Maclear's rat might have been responsible for keeping the population of the Christmas Island red crab in check, as recent numbers of the crab are greater than in the past. It is thought that black rats inadvertently introduced by the expedition infected the Maclear's rats with a disease (possibly a trypanosome), which in turn could have contributed to the species' decline. The last recorded sighting was in 1903, although it is possible that Maclear's rats hybridized with black ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulldog Rat
The bulldog rat (''Rattus nativitatis'') is an extinct species of rat formerly endemic to Christmas Island in the Indian Ocean. It was one of two rats endemic to Christmas Island, alongside Maclear's rat. Description The head and body length was about , considerably larger than black rats, and their backs were covered in a two-centimetre thick layer of fat. They have been estimated to weigh . They had short, thick tails estimated to be around long. Their hair was described as being thick, coarse and dark reddish-brown in colour, with a slightly lighter underside. Despite being traditionally thought to be a part of the genus ''Rattus,'' the bulldog rat is now thought to be nested within ''Bunomys,'' a genus otherwise endemic to Sulawesi and the surrounding islands. Life history The rats lived on the higher hills and denser forests of the island. They lived in small colonies, in burrows among the roots of trees or under hollow logs of sago palms in primary forest An ...

Eulipotyphla
Eulipotyphla (, which means "truly fat and blind") is an order of mammals suggested by molecular methods of phylogenetic reconstruction, which includes the laurasiatherian members of the now-invalid polyphyletic order Lipotyphla, but not the afrotherian members (tenrecs, golden moles, and otter shrews, now in their own order Afrosoricida). Eulipotyphla comprises the hedgehogs and gymnures (family Erinaceidae, formerly also the order Erinaceomorpha), solenodons (family Solenodontidae), the desmans, moles, and shrew-like moles (family Talpidae) and true shrews (family Soricidae). True shrews, talpids and solenodons were formerly grouped in Soricomorpha; however, Soricomorpha has been found to be paraphyletic, since erinaceids are the sister group of shrews, and they are more closely linked to the Carnivora order; (such as cats, dogs, bears, skunks, badgers, etc.). It is the sister clade of Scrotifera; together, they make up Laurasiatheria. Classification * Order Eulipoty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Christmas Island Shrew
The Christmas Island shrew (''Crocidura trichura''), also known as the Christmas Island musk-shrew is an extremely rare or possibly extinct shrew from Christmas Island. It was variously placed as subspecies of the Asian gray shrew (''Crocidura attenuata'') or the Southeast Asian shrew (''Crocidura fuliginosa''), but morphological differences and the large distance between the species indicate that it is an entirely distinct species. Description The Christmas Island shrew, like other members of the genus ''Crocidura'', is a small short-legged mammal with a distinct pointed muzzle. It has a dark grey to reddish brown colouring. Like all other shrews, the Christmas Island shrew resembles a mouse and weighs in a range between 4.5g-6g. The Christmas Island shrew varies from other forms of the species in that it is beset with long fine hairs, and its tail is much greater in length. The typical lifespan for its genus is approximately one year, but Crocidurine shrews have been reported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history.
