Buried Coral’s Slo-Mo Excavation From the Sandy Sea Floor
When I go to the beach and walk out into the waves, I’m always amazed at how quickly my feet become buried in sand thanks to the powerful force of the water rushing over them. Remember what the waves used to do to your sand castles?
Coral can’t just walk out of trouble like we can, though. When sand gets washed over them, they have had to develop numerous ways to uncover themselves, lest they be buried alive. Watch as this mushroom coral inflates and deflates over and over to excavate itself at 300X normal speed.
