Sharks do frequent shallow waters, but they are generally too small, too sluggish, too weakly armed or living at too great a depth to pose any potential danger to humans swimming on the Delaware-Maryland coast. The especially dangerous white shark, in fact, is seldom seen anywhere, especially close inshore. Humans are not the typical prey of sharks, anyway. Most feed on squid and fishes smaller than themselves.
Sharks are also the ocean's garbage disposals.
Opened shark stomachs have revealed soft drink bottles, tin cans, magazines, old clothes, anchors, boat propellers, chum pots, lead sinkers and even logs. BTW, don't confuse the dolphins playing off our coast with sharks. Much of the information on this page courtesy of the University of Delaware Sea Grant Marine Advisory Service.
