Sand divers

One of the frequently encountered predators on the reef is the sand diver. They are typically 12 to 14 inches long. They often rest on top of reef structures, but they also sometimes bury themselves in the sand, with only their head sticking out. When small fishes swim too close, the sand diver darts out to eat them. I'm posting photos of several sand divers, that always seem to be looking for their next meal.
