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.

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.
The name "Mandibulata" refers to the mandibles, a modified pair of limbs used in food processing, the presence of which are characteristic of most members of the group. The mandibulates are divided between the extant groups Myriapoda (millipedes & centipedes, among others) and Pancrustacea (including insects and crustaceans, among others).
Insect mandibles are as diverse in form as their food. For instance, grasshoppers and many other plant-eating insects have sharp-edged mandibles that move side to side. Most butterflies and moths lack mandibles as they mainly feed on nectar from flowers. Queen bees have mandibles with sharp cutting teeth unlike worker bees, who
If you have ever found a creepy-crawly creature in your home and thought to yourself, ‘Ew, it’s a centipede!’ you’re not alone. Centipedes are one of the most common household pests and ...
House centipedes lay their eggs in spring. In a laboratory observation of 24 house centipedes, an average of 63 and a maximum of 151 eggs were laid. As with many other arthropods, the larvae look like miniature versions of the adult, albeit with fewer legs. Young centipedes have four pairs of legs when they are hatched.
The first mandibulates evolved in oceans during the Cambrian period (541 million to 485.4 million years ago) and include modern crustaceans, insects and myriapods, such as centipedes and millipedes.
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 ...
