Centipedes (Class Chilopoda) are fast-moving, venomous, predatory, terrestrial arthropods that have long bodies and many jointed legs. Chiefly nocturnal, centipedes are found primarily in tropical climates but are also widely distributed in temperate zones.

Some species are highly venomous and often produce very painful bites but only one human has actually died from one of these bites- from a bite on the head of a young child by a large centipede on a Pacific island^[1] - though severe reactions have also occasionally been recorded in adults. Centipedes are extremely vulnerable to lack of moisture.^[2]

Like the millipedes, centipedes are highly segmented (15 to 173 segments), but with only one pair of walking legs per segment. Centipedes are dorso-ventrally flattened, and are among the fastest and most agile of non-flying arthropod predators.

The head of a centipede has a pair of antennae, jaw-like mandibles ( called forcipules), and other mouthparts. The most anterior trunk segment of a centipede has a pair of venomous claws (called maxillipedes) that are used for both defense and for capturing and paralyzing prey. The bite of a smaller centipede in temperate areas may be similar to a bee sting, but the bite of a larger tropical species is excruciatingly painful, leaving two black puncture wounds as much as a centimeter apart. Despite their name, which stems from the Latin words centum (meaning 'hundred') and pes, pedis (meaning 'foot'), they normally have around half that number of legs, though it is possible to find centipedes with over 200 legs.

The house centipede (Scutigera coleoptrata) is a fast-moving insectivore that feeds on insects such as cockroaches, house flies, and other small house pests, and is thus beneficial, but its alarming appearance and potentially painful bite often results in its extermination from residences.

Scolopendra gigantea, also known as the Amazonian giant centipede, is the largest existing species of centipede in the world, reaching over 30 cm (12 inches) in length. It is known to eat bats, catching them in midflight, as well as rodents and spiders. The prehistoric Euphoberia was the largest known centipede, growing up to one metre (39 inches) in length.

There are rumors that state that the Galápagos Islands giant centipede (Scolopendra galapagoensis) can reach sizes of up to 60 cm (over 25 in), although these rumours may result from the rarity of the particular centipede. Captive Galapagos centipedes don't often exceed 20 cm (8 inches) in body length.[1]

The garden centipede, the most common centipede in North America, is a much smaller variety, rarely exceeding a few inches in length.

Males spin a small web onto which they deposit a spermatophore for the female to take up. Sometimes there is a courtship dance, and sometimes the males just leave them for the females to find. In temperate areas egg laying occurs in spring and summer but in subtropical and tropical areas there appears to be little seasonality to centipede breeding.

The Lithobiomorpha, and Scutigeromorpha lay their eggs singly in holes in the soil, the female fills the hole in on the egg and leaves it. The young usually hatch with only 7 pairs of legs and gain the rest in successive moults. Scutigera coleoptera, the American house centipede, hatches with only 4 pairs of legs and in successive moults has 5, 7, 9, 11, 15, 15, 15 and 15 before becoming a sexually mature adult. It takes about 3 years for S. coleoptera to achieve adulthood, however, like millipedes, centipedes are relatively long-lived when compared to their insect cousins, for example: the European Lithobius forficatus can live for 5 or 6 years.centipedes are known to live up to 6 to 7 years.

Females of Geophilomorphapha and Scolopendromorpha show far more parental care, the eggs 15 to 60 in number are laid in a nest in the soil or in rotten wood, the female stays with the eggs, guarding and licking them to protect them from fungi. The female in some species stays with the young after they have hatched, guarding them until they are ready to leave. If disturbed the females tend to either abandon the eggs or young or to eat them; abandoned eggs tend to fall prey to fungi rapidly, thus breeding is difficult to study in these species.
