Researchers are examining four dead dolphins that washed ashore on Florida's Canaveral National Seashore.
Biologist Megan Stolen of the Hubbs-SeaWorld Research Institute said the dolphins may have been killed by toxins from a red tide bloom off Florida's Atlantic Coast, The Orlando Sentinel said Thursday.
Red tide has also killed about a dozen green sea turtles during the past few weeks in Brevard County, WKMG-TV (Orlando) reported.
Red tide is suspected to have killed more than 700 dolphins in Florida in 1987 and 100 dolphins in Florida's Panhandle in 2004.
