The mushroom coral, Cycloseris cyclolites, can pack up and “walk” to new habitats and new research has shown that it does so in pursuit of blue light.

A team of scientists used high-resolution time-lapse imaging to discover that C. cyclolites moves using a mechanism known as “pulsed inflation”, which resembles the movement seen in jellyfish.

It inflates and deflates its tissue in rhythmic bursts, dragging itself forward over hours.

This movement helps corals burrow, right themselves, and remove sediment.
