Azorean predacious diving beetle

The Azorean predacious diving beetle (Agabus godmanni) is a species in the genus Agabus. It is currently classified as Endangered on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Chrysococcus biporus is a unicellular chrysophyte alga in the genus Chrysococcus, family Chromulinaceae. Like all members of the genus, the cell is enclosed within a loricate cell covering — a firm, often flask-shaped structure known as a lorica that surrounds the protoplast. The epithet biporus (Latin: two-pored) describes the two openings or pores present in the lorica, through which the flagella emerge. Chrysococcus cells are typically uniflagellate (or with a short, hair-like second flagellum), heterotrophic or mixotrophic, and capable of both photosynthesis and phagotrophic ingestion of bacteria and small organic particles. The genus inhabits freshwater and brackish environments, including oligotrophic and eutrophic lakes, ponds, and wetlands. C. biporus has been recorded from Scandinavian waters, consistent with extensive chrysophyte survey effort in northern Europe. Chrysophytes as a group are important components of freshwater protist communities, playing roles as grazers of bacteria and as prey for larger zooplankton. The species has not been evaluated for conservation status and is listed as Not Evaluated by the IUCN. Molecular surveys are continuing to reveal undescribed diversity within the loricate chrysophyte lineages.
