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.

Yellow-crowned Parrot / Yellow-crowned Amazon

A large, robust amazon parrot found across a broad range from Mexico and Panama through the Amazon basin to Bolivia and Paraguay, yellow-crowned amazons are predominantly green with a variable yellow crown. They inhabit forest, woodland, and savanna and are adaptable enough to thrive in agricultural areas. Multiple subspecies are recognized with differing degrees of yellow on the head. Highly regarded as pet and aviary birds for their speech ability and social temperament.
