they are very opportunistic when it comes to hunting. they have been known to feed on almost anything that they can find, including prey items which they can find in large numbers such as shrimp. they have been known to feed until they actually can not eat any more. since they feed on almost anything that they can find, they have been known to feed on garbage and rubbish such as plastic and rubber tires. this can result in the shark falling ill, and even dying.
