Thus, these sharks would probably look like just another fish to a typically onlooker. “The frequency of one predator eating the other is really about size dynamic,” says Nifong. Alligators normally eat fish, snails and small shellfish but Nifong says they are opportunistic predators, which is why they have been feasting on small sharks and stingrays “If a small shark swims by an alligator and the alligator feels like it can take the shark down, it will” says Nitong. "If a small shark swims by an alligator and the alligator feels like it can take the shark down, it will, but we also reviewed some old stories about larger sharks eating smaller alligators.” Yes, their teeth are sharp as can be and their jaws must me massive. These days, alligator researchers use a technique of evaluating stomach contents from live alligators. I never knew alligators would eat sharks, and sometimes sharks will eat small alligators. That equation — more sharks + more people in the water for more time during the year — equals more shark attacks. So, where do alligators fit into this picture? If a small shark swims by an alligator and the alligator feels like it can take the shark down, it will, but we also reviewed some old stories about larger sharks eating smaller alligators." Frankly, it’s not even close. An alligator's diet typically consists of fish, snails, crustaceans and the occasional unfortunate pet or person. "Both alligators and sharks eat whatever they can." 3 people like this. An alligator's diet typically consists of fish, snails, crustaceans and the occasional unfortunate pet or person. At times, that's each other. Alligators typically eat fish, crustaceans and snails, but Nifong’s research found evidence that they had consumed three species of shark and a type of stingray. Alligators are on the hunt for sharks — and the sharks are attacking back. An alligator's diet typically consists of crustaceans, snails and fish, but because alligators are opportunistic predators, Nifong said sharks may end up on the menu. 24 Oct 17. But scientists just revealed that alligators. 5 people like this. Additionally, alligators usually consume sharks that are considerably smaller than the shark on Jaws. So while alligators normally eat crustaceans and fish, it makes sense that they also can’t resist easy prey in the form of a smaller, younger, or weakened shark. But scientists just revealed that alligators… The sharks measured 3-4ft. Both sure do have the teeth for eating each other. A GREAT white shark appears to have won the battle of the sea monsters – after a crocodile’s head washed up on a beach in South Africa. Shark-gator run-ins are relatively rare, say researchers who study such occasions near NASA's main launch pads.
