The wrinkle-faced bat (Centurio senex) is a species of bat in the family Phyllostomidae and the only identified member of the genus Centurio. This bat is found in various countries in and around Central America. It eats fruit but is not classified within the fruit bats, and is instead classified as a leaf-nosed bat even though it does not have a leaf nose. [2] It has an unusually shaped skull which is thought to allow it to eat a wider range of foods than other bats. [3]
Centurio senex is tail-less, medium-sized, and generally has a pelage of a drab brown to yellowish-brown color. [2] It weighs around 17g. [3] Its face is hairless and is covered by convoluted outgrowths of skin (hence the name wrinkle-faced). These skin flaps are more pronounced in males than females. Males also possess a skin mask that can be used to cover their face. The wrinkle-faced bat has storage pouches in its mouth to allow it to store fruit. C. senex subsp. greenhalli differs from the more common C. senex subsp. senex by being larger and in having a more domed braincase, better developed sagittal crest, and relatively shorter maxillary toothrow. [2] Their skulls are extremely short and wide, which is thought to allow them to produce bite forces up to 20% higher than other bats of a similar size. They are able to generate the largest biting force, relative to their size, of any of the leaf-nosed bats. [3]
The species is entirely frugivorous (fruit-eating) although it is not known which types of fruit it consumes. [2] Elizabeth Dumont from the University of Massachusetts believes that the strong biting force of the bat allows them to survive through times when soft fruit (such as soft bananas, mangoes, papayas, etc.) [4] [5] is scarce as they are able to eat tougher fruit than other bats. [3] Seed predation has been recorded in Mexican populations, which has been suggested as another function of the bite force. [6]
Females are thought to be both polyestrous and asynchronous, pregnant females have been recorded every month between January and August except May. Males emit a musky odour from the chin area to attract females. Their sperm morphology is unique in that the sperm head has a rounded nucleus and extremely pointed acrosome. [2]
Recent research on the bats in Costa Rica suggests that the bats exhibit Lek mating. [7]
Centurio senex subsp. senex is found in Belize, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama and Venezuela. [1] C. senex subsp. greenhalli is only found in Trinidad and Tobago. [2]
The binomial name Centurio senex is formed from the Latin centurio meaning division into hundreds and senex referring to old people. This name was chosen as it was thought that the face of the bat looked like that of a one-hundred-year-old man. [2]
Vampire bats, members of the subfamily Desmodontinae, are leaf-nosed bats currently found in Central and South America. Their food source is the blood of other animals, a dietary trait called hematophagy. Three extant bat species feed solely on blood: the common vampire bat, the hairy-legged vampire bat, and the white-winged vampire bat. Two extinct species of the genus Desmodus have been found in North America.
The New World leaf-nosed bats (Phyllostomidae) are bats found from southern North America to South America, specifically from the Southwest United States to northern Argentina. They are ecologically the most varied and diverse family within the order Chiroptera. Most species are insectivorous, but the phyllostomid bats include within their number true predatory species and frugivores. For example, the spectral bat, the largest bat in the Americas, eats vertebrate prey, including small, dove-sized birds. Members of this family have evolved to use food groups such as fruit, nectar, pollen, insects, frogs, other bats, and small vertebrates, and in the case of the vampire bats, even blood.
The spectral bat, also called the great false vampire bat, great spectral bat, American false vampire bat or Linnaeus's false vampire bat, is a large, carnivorous leaf-nosed bat found in Mexico, Central America, and South America. It is the only member of the genus Vampyrum; its closest living relative is the big-eared woolly bat. It is the largest bat species in the New World, as well as the largest carnivorous bat: its wingspan is 0.7–1.0 m (2.3–3.3 ft). It has a robust skull and teeth, with which it delivers a powerful bite to kill its prey. Birds are frequent prey items, though it may also consume rodents, insects, and other bats.
The Honduran white bat, also called the Caribbean white tent-making bat, is a species of bat in the family Phyllostomatidae. It is the only member of the genus Ectophylla. The genus and the species were both scientifically described for the first time in 1892. It has distinctive, entirely white fur, which is only found in six of the roughly 1,300 known species of bat. It constructs "tents" out of understory plant leaves by strategically cutting the leaf ribs with its teeth; it roosts in these tents during the day. It is a specialist frugivore, consuming almost exclusively the fruits of one species of fig. Females can likely become pregnant twice per year, giving birth to one offspring at a time.
The little white-shouldered bat is a species of bat from South and Central America. It is the only species within its genus, the name of which translates as "reaper" or "destroyer".
The Brazilian big-eyed bat is a species of phyllostomid bat from South America. The scientific name honours Italian naturalist Giacomo Doria.
The visored bat,, is a bat species from tropical South America. It is the only species in the genus Sphaeronycteris. Although visored bats have some unique characteristics, they are thought to be most closely related to little white-shouldered bats and wrinkle-faced bats.
The tent-making bat is an American leaf-nosed bat (Phyllostomidae) found in lowland forests of Central and South America. This medium-sized bat has a gray coat with a pale white stripe running down the middle of the back. Its face is characterized by a fleshy noseleaf and four white stripes. Primarily a frugivore, it may supplement its diet with insects, flower parts, pollen, and nectar. Its common name comes from its curious behavior of constructing tents out of large, fan-shaped leaves. These roosts provide excellent protection from the tropical rains, and a single tent roost may house several bats at once. This bat is quite common in its geographic range; hence, its conservation status is listed as Least Concern.
The Neotropical fruit bats (Artibeus) are a genus of bats within the subfamily Stenodermatinae. The genus consists of 12 species, which are native to Central and South America, as well as the Caribbean.
Carollia is a genus of bats often referred to as the short-tailed fruit bats. Along with the genus Rhinophylla, Carollia makes up the subfamily Carolliinae of family Phyllostomidae, the leaf-nosed bats. Currently, nine species of Carollia are recognized, with a number having been described since 2002. Members of this genus are found throughout tropical regions of Central and South America but do not occur on Caribbean islands other than Trinidad and Tobago. Bats of the genus Carollia often are among the most abundant mammals in neotropical ecosystems and play important roles as seed dispersers, particularly of pioneer plants such as those of the genera Piper, Cecropia, Solanum, and Vismia. Carollia are primarily frugivorous; however, C. perspicillata, C. castanea, and C. subrufa are known to feed on insects.
The Jamaican fig-eating bat is a species of bat in the family Phyllostomidae. It is the only living species in the genus Ariteus. The scientific name translates as "yellowish and warlike". There are no recognised subspecies.
The Honduran fruit-eating bat is a species of bat in the family Phyllostomidae. It is found in El Salvador, Honduras, and Nicaragua.
The flat-faced fruit-eating bat is a South American species of bat in the family Phyllostomidae. It is sometimes considered a subspecies of the Jamaican fruit bat, but can be distinguished by its larger size, the presence of faint stripes on the face, and of a third molar tooth on each side of the upper jaw. Genetic analysis has also shown that the two species may not be closely related.
The buffy flower bat is a species of bat in the leaf-nosed bat family, Phyllostomidae. It is found in the Bahamas, the Cayman Islands, Cuba, and Jamaica.
The greater long-nosed bat or Mexican long-nosed bat is a species of bat in the family Phyllostomidae. It is found in Mexico and the United States. It chiefly consumes pollen and nectar, particularly from agave plants and cacti. Its habitat includes desert scrub and open woodlands, however, it is threatened by habitat loss.
Stenodermatinae is a large subfamily of bats in the family Phyllostomidae.
