What eats jellyfish?

The kids and I were enjoying the beautiful weather yesterday! The kids were riding their scooters and writing with sidewalk chalk on the driveway. We decide to draw a beach scene, since that is our favorite place to go! I drew the ocean and filled it with many types of fish and a jelly fish. As I was finishing the jellyfish Harrison said, "Mommy, do you know what eats jellyfish?" I was waiting on a reply like sharks or something silly. He said "Leather back Sea Turtles!" I did not know if this was true since I have never studied leather back sea turtles so I asked him where he heard that from, he replied "Diego taught me that!" This made me feel much better about letting the kids watch TV! Now I also know that Leather back Sea Turtles eat jellyfish!!
