That's because commercially available sonar systems, which are designed to create signals beyond the range of hearing of such animals, also emit signals known to be within their hearing range, scientists have discovered. The sound is likely very soft and audible only when the animals are within a few hundred meters of the source, say the authors...

2014-01-24 12:56:12

Brett Smith for redOrbit.com - Your Universe Online As male túngara frogs call from their puddles to attract females, they create ripples that spread across the water. According to researchers at the Smithsonian Tropical Research Institute (STRI) in Panama, these ripples are used by other male frogs to assess their competition – and also by bats looking for their next meal. If it sees a bat flying overhead, a male túngara will stop calling – yet ripples continue moving for several...
