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.

Hipopótamo Anfibio

El mamífero terrestre grande más peligroso de África, el hipopótamo común (Hippopotamus amphibius) puede alcanzar los 3.200 kg y habita ríos, lagos y humedales del África subsahariana. Semiacuático, pasa hasta 16 horas diarias sumergido para mantenerse fresco y pace en tierra por la noche. Pese a su apariencia tranquila, es extremadamente agresivo y territorial, responsable de cientos de muertes humanas cada año. Clasificado como Vulnerable, sus poblaciones están amenazadas por la pérdida de hábitat y la caza furtiva de colmillos de marfil.
