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.

Salinicoccus roseus is a pink to rose-pigmented, halophilic Gram-positive coccus found in saline habitats. It inhabits salt lakes, solar salt pans, and hypersaline soils across arid and coastal regions worldwide. This aerobic chemoheterotroph produces carotenoid pigments that may protect it from high-intensity sunlight in its exposed saline environment.
