It is the world’s largest cattle species. <em>Bos gaurus</em> is endemic to south and southeastern Asia, and today, the majority of its population occurs in India. It is sexually dimorphic, with adult males having a distinctive dorsal ridge and often a dewlap. Although <em>B. gaurus</em> consumes numerous browse species, it is primarily a grazer. Except for older males, all other <em>B. gaurus</em> are nearly always found in herds. It is classified as a Vulnerable species, and in 2011–2012, the first reintroductions of <em>B. gaurus</em> occurred in central India.</p>  a0076-3519
