Breathtaking ‘Blue Holes’
Posted by zion on Jan.27, 2009, under Around The World
A ‘Blue Hole’ is sometimes known as a vertical cave, named due to their dramatic contrast between the dark blue and deeper waters of their depths compared to the lighter blue waters of the shallow parts all around their mouth. The water in those depths seldom gets circulated out and as such have very low oxygen content, making them non-conducive to most sea-life but bacteria. But they can be awesomely amazing to behold as you can see.
