All sharks have the "hole" behind they eye. it is called a spriacle, its actually a opening that allows them to suck water in and pass it over the gills as it vacates the body. I am certian now this is a young nurse shark. as far as the coloring goes, i can only assume that what this is a stage in the sharks life as it passes into adulthood that has the coloring changing from what could be "camoflauge" for a young shark to hide turning into the adult coloring being more of that brown/gray coloring decided by the genes of the shark itself. I think what you have captured on film here is a young nurse shark mid-transition to adulthood. i did not read enough to know at what "age" this typically happens, but as a shark when young is more vunerable to other predators they have more camo coloring to help them hide in reefs, seaweed, that type of environment, as they grow and become the hunter/predator they do not need as much camoflauge so they "transition" to the mature coloring of the type of shark they are.
but i am certain this is a older young nurse shark, maybe a year or two... the coloring still indicates to me with the dappled color like the light from the surface makes on the ocean floor that this shark is still an "ambush" feeder and not a fully fledged "hunter" yet.
does that make sense at all?
