Gliding silently beneath the waves they turned vast areas of blue water to gold off the northern tip of the Yucatan Peninsula. Sandra Critelli, an amateur photographer, stumbled across the phenomenon while looking for whale sharks. She said: 'It was an unreal image, very difficult to describe. The surface of the water was covered by warm and different shades of gold and looked like a bed of autumn leaves gently moved by the wind. 'It's hard to say exactly how many there were but in the range of a few thousand. 'We were surrounded by them without seeing the edge of the school and we could see many under the water surface too. 'I feel very fortunate I was there in the right place at the right time to experienced nature at his best.' Measuring up to 7ft (2.1 meters) from wing-tip to wing-tip, Golden rays are also more prosaically known as cow nose rays. They have long, pointed pectoral fins that separate into two lobes in front of their high-domed heads and give them a cow-like appearance. Despite having poisonous stingers they are known to be shy and non-threatening when in large schools. The population in the Gulf of Mexico migrates, in schools of as many as 10,000, clockwise from western Florida to the Yucatan.
Pretty cool. We see a lot of these at the beach by our condo on Sanibel Island (West Gulf Coast of Florida). Hence the "Sanibel Shuffle". You have to shuffle your feet when you go out into the water to avoid getting stung. The stingrays come right up to you and swim around, which is pretty cool. They are very curious creatures. But as you can see by their color in the pictures, they are hard to see when they swim lower in the water(against the Gulf Coast sand, which is tan/brown). Those are amazing pics!
