Banded eagle ray

The Banded eagle ray (Aetomylaeus nichofii) is a species in the genus Aetomylaeus. It is currently classified as Vulnerable on the IUCN Red List. Native to Asia, inhabiting ecosystems characteristic of the region.

Chrysococcus furcatus is a freshwater chrysophyte microalga in the genus Chrysococcus, class Chrysophyceae, order Chromulinales. The species epithet furcatus — forked — describes a bifurcate or forked element of the lorica structure, which is the outer case or envelope enclosing the cell body. Lorica morphology is the primary criterion for species identification in Chrysococcus, with different taxa having characteristic shapes including spherical, heart-shaped, flask-shaped, and various elaborated forms with spines, pores, or processes. C. furcatus has been recorded from Norwegian and Swedish freshwater environments, contributing to the well-documented chrysophyte diversity of Scandinavian lakes and freshwater bodies. Some records also indicate its occurrence in Brazilian and Danish waters, suggesting a broad if patchy distribution across different climatic zones, potentially through passive wind or waterfowl dispersal of dormant cysts. The species inhabits the limnetic zone of freshwater systems, particularly clear oligotrophic to mesotrophic lakes where nutrient concentrations are relatively low and chrysophytes thrive. Chrysococcus furcatus engages in photosynthesis using the standard chrysophyte pigment complement and is a component of the freshwater phytoplankton community that contributes to primary production and serves as prey for zooplankton. C. furcatus has not been formally assessed under IUCN criteria and is classified as Not Evaluated. Its documentation in northern European surveys reflects the tradition of thorough freshwater microalgal taxonomy in Scandinavia.
