Velvety free-tailed bat range |
The velvety free-tailed bat [2] (Molossus molossus) is a species of bat found in North, Central, and South America and the Caribbean.
The velvety free-tailed bat is a medium-sized bat, with a length of 4 inches (100 mm) and with a wingspan of 11–13 inches (280–330 mm). This species is brown in color; however, when seen flying around at dusk, it will appear to be black. The tail of the velvety free-tailed bat is long and extends beyond the tail membrane. Its ears are large and round.
The velvety free-tailed bat forages in open areas, above tree canopies, around forest edges, and around streams and ponds. Its diet includes moths, beetles, and flying ants. It is commonly seen at dusk, where it will fly solo, catching insects in the air.
It occurs in the Americas from Argentina north to Cuba and Mexico and also the Florida Keys in the United States. [1] It is very common in the Caribbean.
A velvety free-tailed bat has been observed being killed by a giant centipede ( Scolopendra viridicornis ) in the Amazon. The lone bat had been roosting inside a man-made wooden structure in Cristalino State Park before the centipede grabbed it with its legs and injected venom into its neck. This observation is notable due to the rarity of centipede predation on bats. [3]
Centipedes are predatory arthropods belonging to the class Chilopoda of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful stings, injecting their venom through pincer-like appendages known as forcipules or toxicognaths, which are actually modified legs instead of fangs. Despite the name, no centipede has exactly 100 legs; the number of pairs of legs is an odd number that ranges from 15 pairs to 191 pairs.
The Molossidae, or free-tailed bats, are a family of bats within the order Chiroptera. The Molossidae is the fourth-largest family of bats, containing about 110 species as of 2012. They are generally quite robust, and consist of many strong-flying forms with relatively long and narrow wings with wrinkled lips shared through their genus. Their strong flying form allows them to fly 60 miles per hour using tail winds and at altitudes over 10,000 feet. This makes them unique among bats, as they are the only bat family that withstands the elevation. They are widespread, being found on every continent except Antarctica. They are typically found in caves, abandoned mines, or tunnels.
The Mexican free-tailed bat or Brazilian free-tailed bat is a medium-sized bat native to North, Central, and South America and the Caribbean, so named because its tail can be almost half its total length and is not attached to its uropatagium. It has been claimed to have the fastest horizontal speed of any animal, reaching top ground speeds over 99 mph (160 km/h). It also flies the highest among bats, at altitudes around 3,300 m (10,800 ft).
Scolopendra gigantea, also known as the Peruvian giant yellow-leg centipede or Amazonian giant centipede, is a centipede in the genus Scolopendra. It is the largest centipede species in the world, with a length exceeding 30 centimetres (12 in). Specimens may have 21 or 23 segments. It is found in various places throughout South America and the extreme south Caribbean, where it preys on a wide variety of animals, including other sizable arthropods, amphibians, mammals and reptiles.
The proboscis bat is a species of bat found in South America and Central America. Other common names include long-nosed proboscis bat, sharp-nosed bat, Brazilian long-nosed bat. and river bat. It is the only species in the genus Rhynchonycteris.
Wagner's bonneted bat or Wagner's mastiff bat, is a species of bat in the family Molossidae. It is found in the Americas from Argentina and Peru north to Mexico, and Cuba. Populations in Florida in the United States are now recognized as the Florida bonneted bat
The dwarf dog-faced bat is a species of free-tailed bat from South America. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Paraguay and Uruguay, typically at lower elevations. It is one of two species in the genus Molossops, the other being the rufous dog-faced bat. Three subspecies are often recognized, though mammalogist Judith Eger considers it monotypic with no subspecies. It is a small free-tailed bat, with a forearm length of 28.9–32.5 mm (1.14–1.28 in) and a weight of 5–8 g (0.18–0.28 oz); males are larger than females. It is brown, with paler belly fur and darker back fur. Its wings are unusual for a free-tailed bat, with exceptionally broad wingtips. Additionally, it has low wing loading, meaning that it has a large wing surface area relative to its body weight. Therefore, it flies more similarly to a vesper bat than to other species in its own family. As it forages at night for its insect prey, including moths, beetles, and others, it uses two kinds of frequency-modulated echolocation calls: one type is to navigate in open areas and to search for prey, while the other type is used for navigating in cluttered areas or while approaching a prey item.
The black mastiff bat is a bat species. It ranges from the northern region of South America, most of Central America and parts of southern Mexico.
The European free-tailed bat is a species of free-tailed bat found in the Old World. Other common names include the bulldog bat and the mastiff bat because of the presence of wrinkling on the snout. This bat is found in the Mediterranean region of Europe and in scattered locations across Asia at altitudes from sea level to 3100 m. The range of distribution is from the Canary Islands and Madeira through the whole Mediterranean area, Asia Minor, the Caucasus and the Middle East. In the north to southern France, southern Germany, Switzerland, Croatia and Bulgaria. It was reported from Korea in 1931, but has not been sighted on the Korean Peninsula since then. Populations in Japan, Taiwan and Korea are now considered to be a separate species Tadarida insignis.
Scolopendra is a species-rich genus of large tropical centipedes of the family Scolopendridae.
The Guadeloupe big brown bat is a species of vesper bat. It is found only on the island of Guadeloupe. It is one of the eleven species of bat found on Guadeloupe, and one of three that are endemic.
Miller's mastiff bat is a species of bat in the family Molossidae. It is found in Brazil, Colombia, Costa Rica, Guyana, Mexico, Nicaragua, and Venezuela.
The white-striped free-tailed bat is a species of bat in the family Molossidae. Its echolocation calls are audible to humans, which is a characteristic found in only a few microbat species. The species was formerly classified as Tadarida australis.
The Christmas Island pipistrelle is an extinct species of vesper bat that was found only on Christmas Island, Australia. The last individual bat was seen in August 2009 with no further sightings despite intensive efforts to locate it.
Eumops ferox, the fierce bonneted bat or the chestnut mastiff bat, is a species of free-tailed bat found in the Caribbean and Mexico. Until recently, it was synonymous with Wagner's bonneted bat.
Molossus alvarezi, or Alvarez's mastiff bat, is a species of bat in the family Molossidae, native to the Yucatán Peninsula. It lives within a relative homogenous environment within perennial forests, low forests, and a band of xeric vegetation.
The purpose of this study was to report the third record of bat predation by centipedes worldwide, the first record in the Amazon region.
