While diving in Sipadan at about 3 to 5 meters, one or two adult sharks would swim by minding their own business, pay me no attention, and then go lie in the sand. Maybe adult reef sharks, some with just a touch of white at tip of their dorsal and upper tail fins. Cloudy day, around noon, Olympus TG6 camera, no strobes.

 

 

Yes, it looks like whitetips.
