Although not a great photo, this gives an idea of the huge numbers the school of Chevron Barracuda (Sphyraena Putnamiae) can reach at certain times of year, particularly at Sail Rock, Koh Phangan.

In this shot, the Barracudas have almost blocked the view of the Batfish Pinnacle in the background, and this is only a small section of the school!!.
