I was going through some old photos and came across this, my favorite shark. Only if they were not protected and I had a 80,000 gal aquarium. Anyone want to take a guess?
Now compare to this photo. The Dorsal fin's angle of projection is decreased. It is subtle but the dorsal fin also begins towards the distal base of the pectorals and not the middle like above. Also the head is less sloped. In the first photo the body appears thicker and snout shorter too. I think the first is a sandbar and this is a dusky. Sometimes it is impossible to tell. I can't remember seeing a dusky in a public aquaria. Either I always assume they are sandbars or the are not collected. Not sure. Anyone keeping them.
