Screaming Turtle! Or maybe it's laughing? Juvenile loggerhead turtle (Caretta caretta). (West Palm Beach, Florida)
This was a turtle that was rescued by researchers after not making it out of its nest. After being raised for a bit in captivity, we released them into the wild. This was its first moment in the ocean.
Taken with Canon D60, Sea & Sea housing, 2 x Ikelite DS-125 strobes.
