Behavioral photography is one of my most favourite among all types of photography and by far the hardest too!
Sometimes if you stay long enough on one subject and just watch or predict what they are about to do. You get that magical shot!
There are times you get a blenny fish’s eyes rolling to the back or a skeletal shrimp just about to feast. At times you catch them mating like the callappa crab running around trying to hide their mate in the sand.
Funny moment does happen all you have to do is wait. Patience is the key to get amazing moment shots.
