In the ocean, typically, big fish eat small fish -- and that rule applies even when the small fish is a sizeable shark. A YouTube video making the rounds recently illustrates that maxim, showing a fishermen reeling in a 4-foot black-tip shark off the coast of Bonita Springs, Fla., only to have a huge goliath grouper rush in and eat it in one fell swoop. Atlantic goliath groupers can grow to lengths of 16 feet and weigh more than 700 pounds. In the end, the fishermen in the video, while surprised, have the perfect reaction -- to simply sit back and laugh.
