The long-fingered bat is the first bat species in Europe known to catch and eat fish, scientists say. Weighing around 0.3 ounce (9 grams) and measuring just over 1.5 inches (42 millimeters), the minuscule bat was long thought to feed only on insects. Scientists were therefore surprised to discover fish bones and scales in the bat's feces in 2003. To figure out whether the bats were actively fishing researchers began monitoring the animals' feeding behavior using small radio tracking devices. (source: news.nationalgeographic.com)
