The Heart From a Pig

Daniel rousseau first noticed that something rather odd was happening with bats when he was out on a field trip catching them for his phd. Thesis. 20 years later, he's followed up on his hunch and provoked quite a buzz by showing that these bats do indeed do just that. And iits the very first time that this is kind this kind of strategy found in mammals. We have no other situations where mammals may make insects. Which is it? Is it the sound that's te deterrent, or is it the movement that's e deterrent? Well, it is definitely the sound, because we actually just used the sound to seep wa kind of fec on the predator.
