Colocynth

<em>Citrullus colocynthis</em>, commonly known as Colocynth, is a plant species belonging to the genus <em>Citrullus</em> within the family Cucurbitaceae, the gourd family. This species has a remarkably broad geographic distribution, with documented occurrences across Africa, Asia, Europe, North America, and Oceania. Records include countries such as Madagascar in Africa, Armenia and Turkey in Asia, Bulgaria and Greece among other European nations, Canada and the United States in North America, and Australia in Oceania. Colocynth is a drought-tolerant perennial vine that typically grows in arid and semi-arid environments, including desert margins, sandy soils, and degraded lands. It produces small, round, bitter fruits historically used in traditional medicine across many cultures for their purgative properties. The species thrives in open, sunny habitats with well-drained soils. Its conservation status has not been formally assessed. As a plant, it produces energy through photosynthesis. Biological traits of this species remain poorly documented in the scientific literature. <em>Citrullus colocynthis</em> is recognized as a species of ethnobotanical and pharmacological interest.

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.
