For the last five years, Dr. Pim Bongaerts of University of Queensland’s Global Change Institute has been documenting the lives of corals through time-lapse photography. It all happens too slowly for the human eye, but capturing life in a coral reef over longer periods of time reveals much more about their growth, locomotion, and even their violent competition with each other. The video above is from BBC News: Underwater time-lapse shows secret life of a coral reef.

So what exactly are corals?

Corals actually comprise an ancient and unique partnership, called symbiosis, that benefits both animal and plant life in the ocean. Corals are animals, though, because they do not make their own food, as plants do. Corals have tiny, tentacle-like arms that they use to capture their food from the water and sweep into their inscrutable mouths.

Any structure that we call a “coral” is, in fact, made up of hundreds to thousands of tiny coral creatures called polyps…

In the archives: more coral.

Spend three minutes underwater with the abundant marine life of South Africa's coral reefs. Patterned moray eels, banded coral shrimp, the orange rock cod, the spotted yellow boxfish, and more are featured in episode 15 of EarthTouchTV’s Wild Oceans.

We are constantly underwater in the archives, including this incredible, animal-packed footage of a sardine run and the tranquil Kuroshio Sea Aquarium in Okinawa.

Underwater footage shot whilst scuba diving in the Fiji islands and Tonga. Featuring colorful coral reefs, huge schools of tropical fish, sharks, humpback whales, underwater caves, scuba divers and much more marine life from the south Pacific.
