A dolphin that ended up in a Brooklyn creek on Thursday has died.
The Riverhead Foundation for Marine Research and Preservation said the animal died Friday morning and was brought to shore by environmental officials. It will be taken to the foundation's Long Island headquarters to be studied.
A second dolphin was also found dead near Point Lookout on Long Island, the organization said.
The first dolphin had been spotted Thursday, swimming in a waterway near Coney Island. Police say the dolphin swam under a trash boom at the mouth of the Coney Island Creek during high tide in the morning.
