The endangered Arabian tahr observed drinking seawater in Oman

Abstract

Consumption of seawater is rare among mammals. Following a local report of Arabian tahr drinking seawater, we collected camera trapping data to confirm and measure the frequency of seawater consumption by Arabian tahr. Based on herbivores’ seasonal deficiencies in sodium and other minerals and the infrequency of seawater consumption by Arabian tahr, we postulate the species uses seawater as a mineral supplement, similar to a terrestrial salt lick. As some countries protect salt licks as critical habitat features, we believe these areas where Arabian tahr can access the seashore should be similarly protected to help maintain behaviours that may contribute towards the fitness of this Endangered species.
