Colonial tunicate

<em>Symplegma reptans</em> is a colonial tunicate in the family Styelidae with known occurrences in Mexico, Norway, Sweden, and the United States. This species has not been evaluated by the IUCN. Colonial tunicates in the genus <em>Symplegma</em> form encrusting sheet-like colonies on hard marine substrates, including rocks, shells, and artificial structures, in shallow coastal environments. Each colony is composed of multiple filter-feeding zooids embedded in a common tunic, through which nutrients and metabolites are distributed. The presence of <em>Symplegma reptans</em> across both the North Atlantic and Pacific coastal regions suggests either a wide native distribution or a history of introduction through maritime vectors such as ballast water and hull fouling. As a sessile filter feeder, this species contributes to water column filtration and nutrient cycling within benthic communities. The reproductive biology of <em>Symplegma reptans</em> likely involves both sexual reproduction via larval dispersal and asexual proliferation through budding within established colonies. Biological traits of this species remain poorly documented in the scientific literature.

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.
