These tiny bats weigh between 4 and 8 grams. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Some uncertainty over the distribution of whiskered bats because they are not easily distinguished from Brandt's bats. Adult male whiskered bats have a thin parallel-sided penis while the whiskered bat has a club-shaped penis. •  Some uncertainty over the distribution of whiskered bats because they are not easily distinguished from Brandt's bats. Bats Biology and Behavior. Maximum age recorded in Europe is 19 years but on average whiskered bats only live for four years (Schober & Grimmberger, 1989). (Schober and Grimmberger, 1997), Bats are important predators of many different types of insects, including mosquitoes, which are vectors for many infectious diseases.
