Around high tide most days in the monsoon season, turtles will saunter in to feed in the rock pools on the headland south of Kamala beach in Phuket. They can be difficult to spot and once they’ve had their fill, they are straight off out to sea. I spotted this one as it came up for air, a manoeuvre that takes a couple of seconds, so you have to be quick on the focus and shutter release.
