Beyond corals, the tool has widespread potential for studying other small-scale marine organisms that photosynthesize, such ...

The intricate, hidden processes that sustain coral life are being revealed through a new microscope developed by scientists ...

To better understand how to help corals become more resilient, researchers in Japan studied how quickly corals return to artificial structures compared to natural reefs after bleaching.

Physicists and marine biologists built a quantitative framework that predicts how coral polyps collectively construct a variety of coral shapes.

Time-lapse video shows how a mushroom coral polyp pulses and inflates, flinging its soft body into micro-hops to slowly move itself to a new location.

Hard corals like brain corals aren’t plants or even one large animal. They are made up of individual polyps – related to jellyfish and anemones – that group together, making use of calcium and ...
