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.

Planococcus rifietoensis is a motile, Gram-positive coccus first isolated from the Rifleto salt mine in Italy. It is halotolerant, capable of growing in moderately saline conditions and inhabits salt-influenced terrestrial environments. This aerobic chemoheterotroph breaks down organic compounds in its saline soil habitats.
