There really is no better place for seeing refraction in action than a few metres down. Under a pier. There is something so incredibly beautiful about the play of light in water beneath piers. The shadows and patterns created as the light refracts around the walkway poles and struts. It gives some really stunning underwater patterns and textures.
And because piers provide relative shelter and safety, you can normally find some pretty interesting marine life there too. In this case one lone, curious, snaggle-toothed old giant barracuda who was really rather friendly. Plus a constantly shifting ribbon of hunting trevally, scooting in and out of the shadows. But there were also moray eels in hiding, devil scorpionfish, sleeping lionfish, anemone fish bustling about, and corals in the most dazzling array of colours. And all in bath-warm water. Perfection. I wanted to stay there forever watching the fish!
Dives are normally a bit deeper and a bit shorter than this, but on this occasion we spent a very happy hour and a half in the shallows, soaking up the atmosphere under Lankayan island pier. So I am more than happy to re-live the moment for this week’s WordPress Photo Challenge: Refraction.
