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 Bunomys

The common bunomys (<em>Bunomys chrysocomus</em>) is a small rodent species found in diverse terrestrial and aquatic habitats, including tropical forests and adjacent ecosystems. This species is classified as Least Concern on the IUCN Red List, reflecting a currently stable population without immediate conservation concerns. As a member of the family Muridae, the common bunomys is an endemic rodent of Sulawesi, Indonesia, where it typically inhabits montane forest environments at moderate to high elevations. The species often forages on the forest floor, feeding on seeds, fruits, fungi, and invertebrates. Its diet and foraging behavior make it an important contributor to seed dispersal and nutrient cycling in its native forest ecosystems. The common bunomys is typically nocturnal and solitary in its habits, as is characteristic of many rodents in its genus. Biological traits of this species remain poorly documented in the scientific literature.
