On April 13, Michael McCarty with See Through Canoe Company had an encounter with a large ray just 50 feet away from the shores of St. Pete.
"Even though I spend a lot of time on the water, this is the first manta ray I've seen here in the St. Pete area," McCarty told FOX 13. "I've seen them in other parts of Florida, but never so close to shore."
According to NOAA, manta rays can reach a wingspan of 29 feet, and have been found worldwide, both in oceanic waters and within bays and intercoastal waterways.
Experts said they have been seen in waters with temperatures as low as 66.2 degrees and as high as 86 degrees.
