Frogs send bad vibrations

Tree frogs in tropical rainforests send messages to each other by vibrating the branches of the plants they live on, Boston University scientists have found.

Biologists have discovered that red-eyed tree frogs, which are typically found in Central and South America, can send warnings to each other by shaking branches.

They found male frogs "pluck" branches with their back legs around 12 times per second to create vibrations to warn off competitors.
