Chroococcus cohaerens is a species of cyanobacteria in the family Chroococcaceae, documented from freshwater and aquatic environments. Chroococcus is a genus of small, spherical to hemispherical cyanobacterial cells that typically occur in pairs or small groups of two to four cells, surrounded by individual sheaths that are embedded within a common gelatinous matrix. The cells are dark olive-green to blue-green in color due to the presence of phycocyanin and chlorophyll a pigments. Cyanobacteria of the genus Chroococcus are common components of the periphyton and plankton of nutrient-moderate freshwater bodies in temperate regions. They are found attached to submerged substrates or floating in the water column. Chroococcus species have been documented from a wide range of geographic regions including Scandinavia, where many of the described species in this genus were originally characterized. The species has no significant economic importance and is not considered a bloom-forming taxon. Its conservation status has not been assessed by the IUCN, consistent with the general approach to prokaryotic microorganisms in conservation frameworks.

Comet Darner

<em>Anax longipes</em>, the comet darner, is a large dragonfly in the family Aeshnidae, assessed as Least Concern on the IUCN Red List. It is endemic to the United States, where it inhabits lakes, ponds, and slow-moving rivers with clear water and abundant emergent vegetation. The comet darner is one of the largest North American dragonflies and is distinguished by its brilliant coloration, including a green thorax and a red-spotted abdomen in mature males. The species name longipes refers to its notably long legs. Adults are powerful aerial predators, feeding on a variety of flying insects captured in flight. Larvae are aquatic and predatory, developing in the benthic zone of freshwater habitats where they feed on invertebrates and small vertebrates. The comet darner undertakes seasonal dispersal movements and is most commonly observed near its breeding water bodies during the warmer months.
