Occurrence remarks These are black tip reef sharks we saw while staying at the Haad Tien resort on Koh Tao in 2013. We saw baby reef sharks which was really cool to see. I saw two baby sharks maybe 1-2 feet long that day and was able to get a picture of one of them. The first baby shark was in the shallows of the bay and the second one, which is in the picture, was seen deeper in the bay where the adults were. I'm not sure how many sharks were in the bay but I would take a guess of about a dozen.
