The Sunda clouded leopard is a medium-sized wild cat native to Borneo and Sumatra. It is listed as Vulnerable on the IUCN Red List since 2015, as the total effective population probably consists of fewer than 10,000 mature individuals, with a decreasing population trend. The Sunda clouded leopard is an overall grayish-yellow or gray hue. It has a double midline on the back and is marked with small irregular cloud-like patterns on the shoulders. These cloud markings have frequent spots inside and form two or more rows that are arranged vertically from the back on the flanks. The Sunda clouded leopard has a stocky build and its canine teeth are 2 in (5.1 cm) long, which, in proportion to the skull length, are longer than those of any other living cat. Its tail can grow to be as long as its body, aiding balance.
