Watch How Alligators Make Water Boil with Their Infrasound Mating Calls

This is amazing. During the breeding season, American alligators call for mates with a deep loud roar. It’s preceded by a pulse of infrasound that sets the water dancing.


The phenomenon might create waves that help potential mates find the gators they like best. Or it could just be an accident, a side effect of the way their scutes separate during development. Either way, it’s spectacular.

Is it actually boiling, or is it vibrating. I’ve seen water boil with torpedo sonars before, but always assumed it was because they were operating at such high frequencies. Infrasound (less than 20 Hz) seems pretty low.

Cool vid, though.
