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.

Gray/Purple Heron

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
