Four dolphins found dead on Florida beach

ORLANDO, Fla., Dec. 14 (UPI) -- 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.
