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.

Vibrio cholerae is a Gram-negative, comma-shaped, highly motile aquatic bacterium and the causative agent of pandemic cholera disease in humans. It inhabits coastal estuaries, river deltas, and warm marine environments, often associated with plankton, particularly copepods. This facultatively anaerobic bacterium spreads through contaminated water and food, causing severe watery diarrhea with major public health impact.
