Turtles

This dive at Sipadan is a wall dive. According to the dive instructors, the cliff can plunge down to hundreds of metres; at it's deepest, it can go down to 2000 m! Goodness, that's deeper than the maximum depth a submarine can go.

Turtle 'flying'. By the way they move their flippers, they look like they are flapping their wings.





Turtle setting off, 'taking flight'



Closer encounter:





'What are you looking at, you alien?"




More specifically, these are the Hawks Bill Turtles.






This photo has better colours. This could be because it is taken at shallower waters.



The light from the sun is white light, meaning it is composed of different colours. As it enters the water,the reddish hues attenuate first. That is why at greater depth, the photos looks greenish. ...
Ok, enough of physics for the moment.
