An Australian diver posted video of his recent encounter with a tiger shark pursuing a turtle. The shark’s attention shifted, however, when he noticed the camera-wielding intruder.

In his Facebook post, the diver wrote:

This was not an attack it was simply a warning to get away from his food, you can see how slowly the shark swims up and doesn’t even attempt to bite me, if he wanted me he would’ve had me plain and simple.
