Why langurs drink salt water: Endangered species defies poor environmental conditions and shows remarkable adaptation

A study by the German Primate Center—Leibniz Institute for Primate Research in Göttingen and Leipzig Zoo shows the remarkable adaptability of the critically endangered Cat Ba langurs. Despite low genetic diversity, the langurs have retained key genetic traits that help them survive in their isolated environment on Cat Ba Island in Vietnam. One of these remarkable adaptations is the ability to drink salt water.
