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.

wild boar

The ancestor of domestic pigs, wild boars are robust, omnivorous ungulates weighing up to 200 kg, found from Western Europe through Asia and North Africa in diverse habitats including forests, wetlands, and grasslands. Highly adaptable and prolific breeders, they have become invasive in many regions including North America and Australia. Their rooting behavior disturbs soil and vegetation, influencing forest structure and seed germination significantly.
