Combtooth lantern shark

<em>Etmopterus decacuspidatus</em>, the combtooth lantern shark, is a small deep-sea shark in the family Etmopteridae, assessed as Least Concern on the IUCN Red List. As a member of the lanternshark genus <em>Etmopterus</em>, the species likely possesses bioluminescent photophores along its ventral surface, a characteristic feature of the group used for counter-illumination and possibly intraspecific communication in the deep ocean. The combtooth designation references the multi-cusped tooth structure of the species. Lantern sharks are among the most species-rich shark genera and are distributed across deep oceanic environments worldwide. Specific habitat description and geographic range data are not available for this species in the current record. As with many deep-sea chondrichthyans, comprehensive ecological and biological information is limited. No quantitative biological trait data including body length or weight are recorded for this species.

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.
