Shark ID help please. [Shark encounter]

Sandtiger (Carcharias taurus) in the centre, Sandbar shark (Carcharhinus plumbeus) on the left (not 100 percent sure with this one, maybe Lemon Shark) and Black-tipped Reef Shark (Carcharhinus melanopterus) on the right.

@zoomaniac I believe that it is a lemon, I am not aware that they have sandbar sharks a SWSD.

@SwampDonkey I would have to agree on the lemon shark.
