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.

Rufous-breasted Hermit

A large hermit hummingbird of humid lowland and foothill forests from Central America through the Amazon basin, rufous-breasted hermits have cinnamon-rufous breast and underpart plumage contrasting with bronzy-green upper parts and a long curved bill. Males gather at leks — communal singing assemblies — where they perform vocal displays to attract females. They follow trap-line routes through dense forest understory. Important pollinators of large Heliconia flowers in tropical rainforest.
