The man brought the shark, believed to be a 6-foot Thresher, ashore at the 58th Street beach in Ocean City Wednesday night.
Teddy Lyons tells WMGM-TV the man often kayaks with a bucket of chum and usually catches smaller brown sharks.
After taking some pictures, the shark was released back into the ocean.
Thresher sharks are not known to attack people.
