Nudibranches

Nudibranches, or sea slugs, belong to the opisthobranchs mollusc groups (Opisthobranchia sub-category: Opistho = "backwards"; brankhia = "gills"), and are characterised by having their gills located behind the heart. They possess two pairs of tentacles and a small or almost non-existent shell.

On the coast of the Algarve, at least 150 of nudibranch exist, and due to this they are among the most common species.

For a more detailed study of the species found in the Algarve, we recommend the book "Sea Slugs of the Algarve", available for sale in our shop.
