Striped icebergs are quite a view. They can form a couple different ways. Blue stripes occur when layers of ice melt and refreeze so fast that no bubbles — which scatter light to give icebergs their white appearance — are created.

Coral is actually a living creature, but the human eye rarely catches it moving. This incredibly slow-motion video lets you see the ocean life you don’t notice, before it’s destroyed by climate change.
It has been said that there are passageways and tunnels at the bottoms of wells such as this one…

daniel stoupin, a doctoral candidate in marine biology at the university of queensland, has photographed a variety of coral species using full spectrum light to reveal fluorescent pigments that would otherwise be invisible to the naked eye. each piece (click pic for name) is from the great barrier reef. given the complexity of the techniques used, which involve time-lapse and stereoscopic and focus stacked photography, the images take up to ten hours to produce in the lab.
Short of the top and bottom ones, all of these corals are brain corals of some form.
And they’re gorgeous.
It’s called circumstantial homosexuality.
