Asperococcus ensiformis is a tubular to flattened brown alga forming elongated, sac-like or sword-shaped thalli attached to rocky substrates. It inhabits intertidal and shallow subtidal rocky shores of the North Atlantic and Mediterranean coasts. This photosynthetic macroalga grows on rocks and larger algae in wave-exposed coastal zones.

common grey sea slug

<em>Aeolidia papillosa</em>, commonly known as the common grey sea slug, is a nudibranch mollusc belonging to the genus Aeolidia within the family Aeolidiidae. Despite the species name referencing terrestrial and aquatic habitats including forests and freshwater, <em>Aeolidia papillosa</em> is primarily a marine organism. Its range includes Belgium, Chile, Denmark, Norway, and Sweden, indicating a distribution across the North Atlantic and into South American waters. Common grey sea slug is assessed as Least Concern on the IUCN Red List. The species is typically found in intertidal and subtidal zones, where it preys on sea anemones and stores stinging cells from its prey in its dorsal cerata for defense. Biological traits of this species remain poorly documented in the scientific literature.
