Common Seal

O pinípede de distribuição mais ampla, a foca-comum (Phoca vitulina) habita as costas temperadas e subárticas do Atlântico Norte e do Pacífico Norte. Os adultos atingem até 130 kg e passam tempo aproximadamente igual no mar caçando peixes, lulas e crustáceos e descansando em praias ou rochas. Seus grandes e expressivos olhos são adaptados para a visão subaquática em pouca luz. A foca-comum é uma fonte de alimento fundamental para orcas, tubarões e ursos-polares.

Common Sword-nosed Bat

<em>Lonchorhina aurita</em>, the common sword-nosed bat, is a microchiropteran bat in the family Phyllostomidae, order Chiroptera. It is distributed across northern South America, with confirmed records from Colombia, Ecuador, and Venezuela, typically roosting in caves, tunnels, and hollow trees in humid tropical forests. The species is named for its exceptionally elongated, sword-like noseleaf, one of the most prominent of any bat species, which is thought to play a role in echolocation signal emission and directionality. <em>Lonchorhina aurita</em> is insectivorous, feeding primarily on insects captured in flight through echolocation within forested environments. It is typically gregarious, roosting in colonies that may include hundreds of individuals. Biological traits including average lifespan, body mass, and forearm length under field conditions remain poorly documented in the scientific literature. The species is assessed as Least Concern by the IUCN, with a reasonably broad distribution and populations that are not currently under severe threat, though continued deforestation and cave disturbance in South America may pose growing risks to local colonies over the long term.
