Centipedes have one pair of legs per segment, while millipedes have two. Their heads differ in that millipedes have short, elbowed antennae, a pair of robust mandibles and a single pair of maxillae fused into a lip; centipedes have long, threadlike antennae, a pair of small mandibles, two pairs of maxillae and a pair of large venom claws.

Chewing insects have two mandibles, one on each side of the head. They are typically the largest mouthpart of chewing insects, being used to masticate (cut, shred, tear, crush, chew) food items. They open outwards (to the sides of the head) and come together medially.
Among myriapods, centipedes have strong, bristly mandibles, which have a row of teeth in all centipedes except for members of the order Geophilomorpha. Millipedes have small mandibles, their only functioning mouthparts, as the maxillae are fused to the lower lip ( labium ).
Centipedes are one of the most common household pests and one of the most feared. With their long, segmented bodies and dozens of legs, they’re not exactly cute and cuddly. But what if
S. polymorpha is indigenous to the Southwestern United States and northern Mexico, north to the Pacific coast. [3] [4] It inhabits dry grasslands, forest, and desert; in these habitats, the centipedes generally take up residence under rocks, though they have been observed creating burrows in suitable environments and inside rotting logs.
Centipedes in this family feature a short head, stout antennae, mandibles with a series of pectinate lamellae, a slightly concave labral margin with a row of denticles or bristles, uniarticulate telopodites on the first maxillae, and claws on the second maxillae fringed by two rows of filaments.
Young centipedes have four pairs of legs when they are hatched. They gain a new pair with the first molting , and two pairs with each of their five subsequent moltings. Adults with 15 pairs of legs retain that number through three more molting stages (sequence 4-5-7-9-11-13-15-15-15-15 pairs).
House centipedes typically have 15 legs and can travel 1.3 feet-per-second, which explains why catching one of these centipedes in house is nearly impossible. The typical response to a house ...
