Nudibranchs

A shell-less sea slug whose exposed gills, sensory rhinophores and extravagant colors reward close inspection.

It moves slowly across its food source, following chemical trails that are invisible to a diver.

Some species recycle stinging cells or defensive chemicals from their prey and store them for their own protection.

Perfect your buoyancy and observe from above without touching the animal or the surface supporting it.

The extraordinary colors may provide camouflage, advertise toxicity or imitate another better-defended animal.

Look closely on reef walls, coral heads, sand, seagrass, jetties and shaded overhangs.
