My son came up from Florida for the holidays, and shared some of his videos with me, so I thought I'd share them with you. As you may know, he is a senior aquariast with the Mote Marine Aquarium in Sarasota, Florida. One of his specialties is breeding cuttle fish and octopus. This first one is one of his octopi enveloping and eating a shrimp.
