Moonrat range

The moonrat (Echinosorex gymnura) is a species of mammal in the Erinaceidae family. It is the only species in the genus Echinosorex. The species name is sometimes given as E. gymnurus, but this is incorrect.[1] There are two subspecies: E. g. gymnura is found in Sumatra and on the Malay Peninsula; E. g. alba is found in Borneo.[3]

The moonrat's fur is generally white, with a sparse scattering of black hairs; it appears totally white from a distance. The moonrat has a distinct pungent odour with strong ammonia content, different from the musky smell of carnivores.[4] Moonrats from western Borneo tend to have a greater proportion of black hairs than those from the east, but animals from Brunei appear intermediate.[3]

Head and body length is 320–400 mm, tail length is 205–290 mm, hind foot length is 65–75 mm and weight is 87-–1,100 g.[5] The dental formula is Upper: 3.1.4.3, lower: 3.1.4.3, total: 44.[3]

Distribution

Moonrats inhabit most jungle terrain in southern Myanmar, peninsular Thailand, peninsular Malaysia, Borneo and Sumatra. Although they are closely related to the short-tailed gymnure (Hylomys suillus) and to the hedgehog, full grown specimens more closely resemble large rats, with which they share similar habits and ecological niches.[6] In Borneo, they occur at many sites throughout the lowlands and up to 900 m in the Kelabit Highlands. They appear to be absent or rare in some localities, possibly due to a shortage of suitable food.

Ecology and habitat

Moonrats are nocturnal and terrestrial, lying up under logs, roots or in abandoned burrows during the day. They inhabit moist forests including mangrove and swamp forests and often enter water.[5][2] In Borneo, they occur mainly in forests, but in peninsular Malaysia they are also found in gardens and plantations. They feed on earthworms and various small animals, mostly arthropods.

Behavior and reproduction

Moonrats release strong odours with a strong ammonia content to mark the edges of their territories and warn other moonrats to stay away with threatening hisses also to ward off predators. Adults live alone. When they are preparing to have young, they will make nests mostly from leaves. Females usually have two babies at one time.

Diet

The moonrat is quite an omnivore, known to eat a wide range of invertebrates—for example, worms, insects, crabs and other invertebrates found in moist areas. They will also eat fruit, and occasionally frogs or fish.

Lifespan

The lifespan of the moonrat is up to five years.[7][not in citation given]

Conservation status

The moonrat is not considered a threatened species. The main threat to the moonrat is deforestation activities due to human development for agriculture, plantation, and commercial logging. Moreover, other demands from Penan in Borneo for food and traditional medicinal contribute to decreasing numbers of moonrats in Borneo.[6] The species is also found in protected areas, including Matang National Park and Kuching Wetlands National Park. Its IUCN status is Least Concern.[2]

Economic importance

In the United States of America, members of the family Erinaceidae are commonly kept as pets. The Penan in Borneo used to trade moonrat meat for other foods and goods among themselves and for money.[7][not in citation given]
