Nudibranchs are shell-less gastropods. They are some of the most bizarre-looking underwater animals found in our oceans. They can be challenging to find due to their small size and confusing patterns. Nudibranchs are slow-moving, delicate and lack a protective shell. Some are extremely distasteful and bright colors warn predators that they are toxic. Some even have the ability to ingest stinging cells and use them as a form of protection.

The best way to find sea slugs:    Move slow!  Search around sponges, hydroids, sea squirts, anemones, soft coral, rocks and reef ledges.

Train the eye:  They can be challenging to find, I recommend tagging along with experienced divers that already have an eye for finding them.
