Whale Shark Isla Mujeres, Mexico Feeding on Fish Eggs
Typically, underwater photographers don't like their photos with what we call "backscatter," little white dots caused by underwater strobe light hitting and lighting particulate in the water.
But, in this case, we aren't using any lights; all these white dots are caused by sunlight hitting the fish eggs in the water; the food for a whale shark's filter feeding.
And, yes, we get covered in fish eggs and they get all in our clothes. Hey, this is just nature. Roll with it. :-)
