A dead leopard shark was pulled from an irrigation canal at Santa Ana and Minnewawa avenues in Clovis, police said.
A Clovis Transit bus driver told officials he saw a group of people standing by the canal about noon Tuesday and saw the shark on the side of the canal on his return trip about 20 minutes later.
One witness said the shark looked like it had been dead for a few days, police spokeswoman Janet Stoll-Lee said.
Leopard sharks live off the California coast and need cool saltwater to survive, Stoll-Lee said. They are sold in pet stores and online.
