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.

Rufous-tailed Hummingbird

One of the most common hummingbirds in Central America and northwestern South America, rufous-tailed hummingbirds are medium-sized with green upper parts and a diagnostic bright rufous-orange tail. Found from Mexico to Ecuador and Trinidad in a wide range of habitats including forest edges, gardens, plantations, and secondary growth from sea level to 2,100 meters. Aggressive territory defenders at feeders and flowering plants, they are frequently seen in gardens across their range. Listed as Least Concern.
