The Palawan stink badger (Mydaus marchei), pantot or tuldo in the Batak language, is a carnivoran of the western Philippines named for its resemblance to badgers, its powerful smell, and the largest island to which it is native, Palawan. Like all stink badgers, the Palawan stink badger was once thought to share a more recent common ancestor with badgers than with skunks. Recent genetic evidence, however, has led to their re-classification as one of the Mephitidae, the skunk family of mammals. [3] It is the size of a large skunk or small badger, and uses its badger-like body to dig by night for invertebrates in open areas near patches of brush. While it lacks the whitish dorsal patches typical of its closest relatives, predators and hunters generally avoid the powerful noxious chemicals it can spray from the specialized anal glands characteristic of mephitids.

Description

Although smaller than true badgers, the Palawan stink badger is one of the larger members of the skunk family, the Mephitidae. Adults measure 32 to 46 cm (13 to 18 in) in length, about the same size as the striped skunk native to North America, and weigh anything from 0.85 to 2.5 kg (1.9 to 5.5 lb). In physical appearance, however, they more closely resemble badgers than skunks. They have a pointed snout with a mobile nose, and a stocky body with short and powerful limbs bearing sharply recurved claws. The tail is very short in comparison to the body, measuring only 1.5 to 4.5 cm (0.59 to 1.77 in), and lacking the bushy fur of many skunks. The ears are almost invisible, with only vestigial pinnae, and the eyes are also relatively small. [4]

The fur is dark brown to black over most of the body, fading to a more brownish colour on the underparts. There are also scattered white hairs across the back and over the forehead, but not the white stripe and head-patch found on the closely related Sunda stink badger. Compared with its sister species, the Palawan stink badger is also slightly smaller, with larger teeth and longer fur. Females have six teats. [4]

Distribution and habitat

Palawan stink badgers live on the Philippine island of Palawan, and also on the neighbouring islands of Busuanga and Calauit. [1] They live primarily in the grasslands and cultivated areas on these islands, and use local shrubs for shelter. [5]

The Palawan stink badger was described as "surprisingly common" in the 1970's, however, it is now considered a vulnerable species by the IUCN. It is unclear whether loss of habitat is adversely affecting M. marchei populations, but, being an endemic species that only inhabits two islands, its conservation is of concern. At this time, there does not appear to be any Philippine law protecting the creature, nor is there any conservation work concerning this species being conducted at this time. [6]

Biology

Palawan stink badgers are nocturnal, and feed mainly on invertebrates, such as freshwater crabs and small insects, which they dig out of the ground with their long claws. They are good diggers, and may spend the day in excavated dens. They may travel up to 2 km (1.2 mi) in search of food, and are reported to mark their territory with scent. [5] They are slow moving, and not particularly aggressive, either freezing or emitting a warning snarl when threatened. [7]

Like skunks, Palawan stink badgers possess anal scent glands that emit a pungent yellowish liquid. They are able to spray the liquid up to a metre, [7] and the scent is said to be strong enough to be smelled up to a mile away. [5] The stink badgers rely almost entirely on this powerful odour for their defence, and are among the few wild animals not eaten by the local farmers. [5]

Mephitidae is a family of mammals comprising the skunks and stink badgers. They are noted for the great development of their anal scent glands, which they use to deter predators. Skunks were formerly classified as a subfamily of the Mustelidae ; however, recent genetic evidence has caused skunks to be treated as a separate family. Similarly, the stink badgers had been classified with badgers, but genetic evidence shows they share a more recent common ancestor with skunks, so they are now included in the skunk family. A 2017 study using retroposon markers indicated that they are most closely related to the Ailuridae and Procyonidae.

The striped polecat, also called the African polecat, zoril, zorille, zorilla, Cape polecat, and African skunk, is a member of the family Mustelidae that resembles a skunk. The name "zorilla" comes from the word "zorro", which in Spanish means "fox". It lives predominantly in dry and arid climates, such as the savannahs and open country of Central, Southern, and sub-Saharan Africa, excluding the Congo basin and the more coastal areas of West Africa.

The anal glands or anal sacs are small glands near the anus in many mammals, including dogs and cats. They are paired sacs on either side of the anus between the external and internal sphincter muscles. Sebaceous glands within the lining secrete a liquid that is used for identification of members within a species. These sacs are found in many species of carnivorans, including wolves, bears, sea otters and kinkajous.
