Free-tailed bat
Mexican Bulldog Bats ( Tadarida brasiliensis)
The Bulldog Bats ( Molossidae ) represent a relatively small, widespread family of bats within dar. Worldwide there are about 100 species in 16 genera especially from the tropics known, any one of them, the European bulldog bat ( Tadarida teniotis ) lives in Southern Europe.
Dissemination
Bulldog bats are native to the tropical and subtropical regions worldwide. In America, spread to Argentina from the United States, next to Southern Europe, much of Africa, the southern regions of Asia, Australia and Oceania to the Fiji Islands.
Description
The head of the bulldog bats is characterized by a short, broad muzzle, the lips are wide and fleshy, and often provided with folds or grooves. Their ears are short and wide and often bent forward, eyes, however small. The nostrils sometimes sitting on a bale, which is equipped with spatula -shaped whiskers.
Their wings are long and narrow, but they allow them no abrupt maneuvers, for a long-duration flight. Her short, soft fur is reddish, brown or black in most cases, except for the little hairy nude bats ( Cheiromeles ). The tail is long, its tip extends far out from Uropatagium ( the wing membrane between the legs). Some species move backwards on the ground and use it as a tactile organ.
Way of life
Like most bats are nocturnal, sleeping places as they use caves, rock crevices, buildings, tree cavities and holes in the ground. Often they sleep in large groups with hundreds of thousands of animals, some species, however, live alone. In no way been a hibernation was observed species in cooler regions wander sometimes during the winter months in warmer areas. All species are insectivores, which catch their prey in flight.
