Cuban greater funnel-eared bat
The Cuban greater funnel-eared bat (''Natalus primus'') is a species of funnel-eared bat found in Cuba.〔
''Natalus primus'' is a member of the order Chiroptera and the family Natalidae.〔(【引用サイトリンク】url=http://www.planet-mammiferes.org/drupal/en/node/38?indice=Natalus+primus )〕 The bats within the genus Natalus have had a complex taxonomic history due to its morphological conservatism. The taxonomy of Natalidae has been recently updated by the discovery and rediscovery of live species and fossils, and on the basis of new morphological and molecular evidence. They have funnel-like ears and a tail as long as the head and body combined.〔(【引用サイトリンク】url=http://www.edgeofexistence.org/mammals/species_info.php?id=1400 )〕 They have black, stiff hairs above the upper lip, much like a moustache, and white hairs below the lower lip. They have tan and reddish-brown fur with a paler belly.〔(【引用サイトリンク】url=http://animals.jrank.org/pages/2886/Funnel-Eared-Bats-Natalidae-FUNNEL-EARED-BAT-Natalus-stramineus-SPECIES-ACCOUNT.html )〕 These bats have a diet consisting largely of moths, crickets, and beetles.〔(【引用サイトリンク】url=http://www.iucnredlist.org/details/136777/0 )〕 In 1992, the first living population was discovered in a cave in Cueva La Barca.〔 Caribbean hurricanes early in the evolutionary history of Natalids may account for specialized cave roosting. This species is critically endangered and only inhabits one cave in Cueva La Barca.〔(【引用サイトリンク】url=http://www.cepf.net/where_we_work/regions/CaribbeanIslands/ecosystem_profile/Pages/conservation_outcomes.aspx )〕 The population is abundant in that single cave, but this species is likely to go extinct due to its limited dispersal range,〔 human disturbance and loss of habitat.〔(【引用サイトリンク】url=http://www.wildlifeextra.com/go/news/threatened-species100.html#cr )〕 It is estimated that there are only 100 mature individuals.〔 Natalus primus is known to have become extirpated throughout most of Cuba suggesting a population decline that may have continued until the present. The survival of Cuban bats is threatened by forest destruction and cave modification. Habitat loss through erosion is a major concern. The ongoing collapse of the cave roof is likely to upset the thermal balance in this hot cave and result in Natalus primus extinction.〔 Cave-dwelling Cuban bat species conservation should be a cooperative effort promoting research and habitat management.〔
