Guess What Dolphins and Crickets Have in Common

Dolphins and crickets might have more in common than you think.

A large group of insects that includes crickets and katydids is believed to share a hearing feature with toothed whales like dolphins, according to a new study.

For insects in the Ensifera group, sound is known to be detected by ear drums on the front legs. Researchers looking at the Auckland tree weta, a species in this group, then discovered that noise passes through a sound-transmitting lipid (a compound that includes oils and fats) to get to the insect's hearing organs.
