These strange animals with their very long front legs are known as whip-spiders or whip-scorpions. With animals like the romans, scorpions and ticks they belong to the class Arachnida, a group of animals all with eight legs. However, they are not true spiders as they do not produce any silk or venom. Scientifically they are placed in the order Amblypygi and they form a distinct group on their own. Their common name refers to the whiplike movements of their first pair of legs.

Whip-spiders are flat animals and their colour varies from dark brown to yellowish-brown with numerous dark spots and markings over their bodies and legs giving them a mottled appearance, which enables them to blend in with their surroundings. They are fairly large and can reach a size of upto 20 mm. The head and thorax part of the body is wider than long and bears the eight small eyes arranged in three groups. The middle pair of eyes is near the fore-edge with two groups of three eyes each on either side. Their mouthparts consist of short chelicerae with two segments. The palpi are very large and powerful and resemble the pincers of scorpions. They are darker than the rest of the body and bear many strong and sharply pointed tubercles and setae on the inside, which they use to grasp and secure their prey. It is the presence of these palpi that gives these harmless creatures their fearsome look. They do not possess any venom, and only use their palpi to grab and hold their prey.

The abdomen is oval-shaped and consists of twelve transverse segments. The first segment forms the stalk with which the head and thorax are attached to the abdomen. They have eight legs with the first pair being very long, slender and whiplike in appearance. In a full grown specimen the front leg may measure upto 25 cm from tip to tip. These legs are provided with numerous sensory organs. They are not used in walking and are exceptionally mobile. While the owner rests, it is in constant touch with the surroundings, gently turning and twisting in a curious manner. The front legs are also used during courtship.

Whip-spiders are known only from tropical America, Africa and Asia. There are only five species in southern Africa and by far the most common and widespread species is Damon variegatus. Their distribution throughout South Africa seems to coincide roughly with areas not receiving night frost. They are found in woodland as well as savanna areas and are found under bark of trees, cracks and crevices in rocks and in leaf litter. In Natal they also occur in houses and outbuildings. They are absolutely harmless to man and neither bite nor sting.

They are hardy animals and can survive long periods without food or water. They are meat eaters and are not very selective in choice of prey. Virtually any invertebrate that they can overpower is taken. The prey is captured with the palpi while the chelicerae cut off pieces, which they masticate before they start to feed.

Some species are found under the bark of trees and even in dead wood. They are shy nocturnal animals. They are very agile and their flattened bodies enable them to scurry into narrow slits under rocks or bark when disturbed. They drink water and use their pincers to bring the water to their mouths when drinking. Whip-spiders take about two years to reach maturity and live for several years. During the rainy season an average of 36 eggs is produced which the female carries in a dark and slightly transparent sac attached to the ventral surface of her abdomen. The developing eggs and embryos are fed by the mother through a connection with her body. Like scorpions the young are carried on the mother's back for a period of time before they disperse.

Whip-spiders play an important role in the balance of nature, are an asset and need to be protected. Their prey includes insects like crickets, locusts, termites and cockroaches.
