Lisa Hoopes (left), a nutritionist with the Georgia Aquarium in Atlanta, and Samantha Ehnert, with the University of North Florida, examine a Cannonball jellyfish netted from the water about a mile from Ponce Inlet near Daytona Beach, Tuesday, Jan. 23, 2018. Hoopes and Ehnert are aboard the M/V OCEARCH to take samples of sharks while on an expedition along the coasts of the Carolinas, Georgia and Florida. "I'm interested in the feeding and nutritional ecology of the sharks we finds," said Hoopes. "By taking samples of sharks in the wild and analyzing those results, we can get a better idea of how to keep the sharks in our collection at the aquarium healthy."
