THE FURRY HEDGEHOG

-

Think all hedgehogs are spiky! Think again. The aptly named furry hedgehog sports a fine pelt of floof with ne’er a prickle in sight.

Furry hedgehogs, also known as gymnures, are found in the subtropica­l evergreen forests of Southeast Asia, including Vietnam, Sumatra, China and the Malay Peninsula.

Their pointy snouts are hedgehog-like and their naked tails are rat-like, but there’s also something of the shrew about them. They’re not, however, closely related to rats, and instead nestle happily within the family of Erinaceida­e, which incorporat­es both furry and spiky hedgehogs alike.

Where regular hedgehogs have spines made from stiff, hollow, keratin-dense hairs, furry hedgehogs, which are thought to have evolved before their spiky relatives, are covered in dense fur. Depending on the species, the fur can be soft or bristly, and the size can vary considerab­ly. In Indonesia, for example, the dwarf gymnure grows to about the same size as a house mouse, while a different variety, known as the white-faced moonrat, grows as big as a domestic cat.

The body plan of furry hedgehogs is thought to resemble that of the earliest mammals, with a long, pointy head, a naked tail for regulating body heat and a plantigrad­e stance, which sees the base of all four feet firmly in touch with the ground.

Like the regular hedgehogs you might find in your garden, they’re omnivores. Foraging in darkness or the twilight hours, furry hedgehogs use their bristly whiskers to help them find worms, insects, scorpions, spiders, frogs, fish, fruit and other delicacies. The solitary beasts also have a strong scent, likened to rancid garlic, which they produce from scent glands and use to mark their territory.
