Meat-eating and fish-eating bats
Other bats have taken to feeding on meat. Some prey on roosting birds, some take frogs and small lizards. The Yellow-eared bat (Phyllostomus hastatus) even feeds on other bats. An Americanspecies even manages to fish (Noctilo leporinus). At dusk, it beats up and down over ponds, lakes, or even the sea. The tail membrane of most bats extends to the ankles. In the fishing bat, it is attached much higher up at the knee, so that the legs are quite free. The bat can therefore trail its feet in the water, keeping the membrane out of the way by folding up its tail. Its toes are large and armed with hook shaped claws. When they strike a fish, the bat scoops it up into its mouth and kills it with a powerful crunch of its teeth.
