Rats, often anthropomorphized as greedy and selfish, may not be the callous, cartoon villains they are sometimes made out to be. A paper published today in Science demonstrates that the rodents will liberate trapped cage-mates — even when they have nothing to gain.
"From deafening monkey howls to snapping crustacean claws, animals use powerful sounds to do everything from claim territory to stun prey.
"There’s such an enormous range of abilities and loudness in animals, it's very easy to get swept up by it all. I just love this stuff," said bioacoustician Christopher Clark of Cornell University.
While every animal sound is amazing in its own right, the result of millions of years of evolution, Clark and other researchers have a few favorites. In this gallery we review the best, and look at the physics that produce them."
