Colorful Close-Ups From a Remote Coral Reef

Kike Ballesteros has been the Pristine Seas team expert on coral and algae since the beginning.

Now, diving on the current expedition to Niue Island, a raised coral atoll in the South Pacific, Kike reveals some of his most colorful and finely detailed images yet of the strange and beautiful creatures that call the bottom of the ocean home.

And lest you think that algae and coral are just a pretty backdrop for all the glorious fish, see what Kike had to say on an earlier expedition, explaining how these tiny life forms are responsible for feeding the ocean and building the beach.

[Updated 10/3/16. Earlier text mistakenly called Niue “the world’s largest coral atoll.” Lifou Island in New Caledonia is the largest.]
