Wildlife activists in Britain have spotted a type of bat that was declared extinct in 1992. The bat, known as the "Lone Boy," is large and has enormous ears; the last sighting of it after its extinction declaration was in 2019. Since then, fears among scientists about the potential absence of this bat have increased, as it has not been seen again. Dr. Fiona Matthews, the president of the British Mammal Society, urged the public to look for more of these bats, according to the British newspaper "Daily Mail." Matthews added, "There may be some in Sussex, Hampshire, or Dorset. They are often found in Europe in lavish homes, castles, or large barns." The "Lone Boy" is the largest of the 11 bat species, with wings that can stretch nearly 50 centimeters while flying. This species of bat can live for over 35 years and remains motionless in its roost for about five months each winter during hibernation.
