<em>Comatricha laxa</em> is a plasmodial slime mold in the class Myxomycetes, order Stemonitidales, with a documented distribution spanning Asia, Europe, and South America. As a member of the genus <em>Comatricha</em>, it forms stalked sporangia with a characteristic capillitium that forms a loose, open network aiding spore dispersal. The species inhabits rotting logs, dead bark, and moist leaf litter in forested environments where conditions support the plasmodial feeding stage. The plasmodium is a multinucleate, macroscopic structure that migrates over substrates to engulf bacteria and other microorganisms. Geographic range data confirm a wide cosmopolitan distribution in suitable habitats across three continents. <em>C. laxa</em> contributes to decomposition and nutrient cycling in woodland ecosystems. No quantitative biological metrics such as body size or mass are applicable to this organism, and it has not been evaluated by the IUCN.

Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
