"I haven't seen sharks feeding right on the shoreline before, with sharks being thrown up into the intertidal zone," senior fisheries biologist Gregory Skomal told National Geographic, adding that the footage shows behavior he'd consider pretty rare. "They are so ravenous that they are only thinking about feeding. It's remarkable." Skomal said these were blacktip or sandbar sharks that were after young snapper blues no more than 8 inches long. It appears that all the sharks made it back into the tide unharmed and unlikely to regret their large meal.
