Researchers are catching a wide range of sharks off New York’s Hamptons and outfitting them with small trackers as they seek to understand more about one of the world’s few confirmed great white shark nurseries. The Associated Press came along to document one recent research excursion. The scientists say they're seeing more exotic sharks coming up during the summer months as local waters warm. They also say young white sharks are moving north sooner because of the warming waters, potentially putting them at risk of becoming prey to older sharks.

Nate Rouette and his brother Nelson went shark fishing on Cape Cod hoping for an exciting catch, but were shocked by what they reeled in. The brothers caught a tiger shark, a tropical species with a reputation for eating everything it can swallow. The brothers, longtime sport fishermen who live in Massachusetts, caught and released the juvenile shark in July. The shark is far more common in warmer, southern waters such as the Caribbean Sea. Scientists say its appearance off Falmouth, Massachusetts, is an indicator of warming seas caused by climate change.
