Sir David Attenborough's myotis (Myotis attenboroughi) is a species of small bat in the family Vespertilionidae that is endemic to the Caribbean island of Tobago. Its presence on nearby Trinidad is as yet uncertain. It is the only mammal species currently known to be endemic to Trinidad and Tobago. It was named after famed English naturalist Sir David Attenborough.
It was formerly assigned to Myotis nigricans until a 2017 study revealed that it was a distinct, previously unknown species. It is the sister species to a clade containing M. cf. handleyi, M. nesopolus , and 3 possibly undescribed species from South and Central America. It can be distinguished from all other Caribbean Myotis by its small skull and steeply sloping frontals.
It feeds on moths and other small flying nocturnal insects, and roosts in caves, tree hollows, and the attics of buildings. [1]
Sir David Frederick Attenborough is a British broadcaster, biologist, natural historian, and writer. He is best known for writing and presenting, in conjunction with the BBC Studios Natural History Unit, the nine nature documentary series forming the Life collection, a comprehensive survey of animal and plant life on Earth.
Trinidad is the larger and more populous of the two major islands of Trinidad and Tobago. The island lies 11 km (6.8 mi) off the northeastern coast of Venezuela and sits on the continental shelf of South America. It is often referred to as the southernmost island in the West Indies. With an area of 4,768 km2 (1,841 sq mi), it is also the fifth largest in the West Indies.
Trinidad and Tobago are continental islands with a geologically very recent history of direct land bridge connection to South America. As a result, unlike most of the Caribbean Islands, Trinidad and Tobago supports a primarily South American flora and fauna and has greater diversity of plant and animal species than the Antilles. However, rates of endemism are lower than in the rest of the Caribbean because there has been less time for genetic isolation from mainland populations because of the history of land bridge connections and hence fewer opportunities for speciation, and so a greater proportion of the species in Trinidad and Tobago are also found on the South American mainland. Trinidad is nearer to mainland South America and has been directly connected to the mainland via land bridges more often and for longer periods than Tobago. This, as well as Trinidad's larger size and more varied topography and hydrology compared to that of Tobago allow greater species and ecosystem diversity on the former compared to that on the later of the islands.
The mouse-eared bats or myotises are a diverse and widespread genus (Myotis) of bats within the family Vespertilionidae. The noun "myotis" itself is a Neo-Latin construction, from the Greek "muós and "oûs", literally translating to "mouse-eared".
Main Ridge is the main mountainous ridge on the island of Tobago, Trinidad and Tobago. It is a 29-kilometre (18 mi) chain of hills which runs from southwest to northeast between the Caribbean Sea and the Southern Tobago fault system and reaches a maximum height of 572 m (1,877 ft). The Main Ridge Forest Reserve, which was legally established in 1776, is one of the oldest protected areas in the world. It is a popular site for birdwatching and ecotourism. Main Ridge provides important habitat for native plants and animals, including several species endemic to Tobago.
The black myotis is a vesper bat species from South and Central America.
The velvety myotis, is a species of vesper bat from South America.
Hodgson's bat, also called the copper-winged bat or black-and-orange myotis, is a species of vesper bat in the genus Myotis, the mouse-eared bats. Favouring mountain forests, it is found throughout Central, Southeast, and East Asia, from Afghanistan to Taiwan. It is about 5 centimetres (2.0 in) long and is distinguished from most other species of bat in this range by its yellowish colouration.
The southwestern myotis is a species of vesper bat. It is found in Guatemala, Mexico, and the United States.
The flat-headed myotis is a species of vesper bat. It is endemic to Mexico where it is found in certain montane forests in the Sierra Madre Oriental in the northeast of the country. Once thought to be extinct, this bat was rediscovered in 2004 by Joaquín Arroyo-Cabrales and colleagues. The species is now classified as endangered by the IUCN.
Myotinae is a subfamily of vesper bats. It contains three genera: Eudiscopus, Myotis, and Submyotodon. Before the description of Submyotodon and analysis of its phylogenetics, as well as a phylogenetic analysis of Eudiscopus, the only member of Myotinae was Myotis.
David's myotis is a species of microbat in the Vespertilionidae family native to China, Mongolia, Kazakhstan, and Russia. First identified in 1869 by Wilhelm Peters, it is similar in morphology to species like M. mystacinus, M. ikonnikovi, M. brandtii, and M. sibiricus. It was previously considered to be a subspecies of the whiskered bat.
The Barbados myotis is a species of bat found in the Lesser Antilles. It was previously considered a subspecies of Schwartz's myotis, Myotis martiniquensis, but was elevated to species rank in 2012.
Myotis izecksohni is a species of mouse-eared bat that is endemic to Brazil and Argentina.
Myotis annatessae is a recently described species of bat in the family Vespertilionidae. It is endemic to Vietnam and Laos.
The Nimba myotis, also known as the orange-furred bat or Nimba Mountain bat, is a species of bat in the family Vespertilionidae. The species is endemic to the Nimba Mountains in Guinea, West Africa. It was discovered in 2018 and officially described in 2021 by a team of scientists from the American Museum of Natural History in partnership with a team from The University of Cameroon, which was led by American mammalogist Nancy Simmons.
The long-toed myotis or Taiwan long-toed myotis is a species of vesper bat endemic to Taiwan.
