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.

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 ).
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).
The mouthparts of arthropods have evolved into a number of forms, each adapted to a different style or mode of feeding. Most mouthparts represent modified, paired appendages, which in ancestral forms would have appeared more like legs than mouthparts. In general, arthropods have mouthparts for cutting, chewing, piercing, sucking, shredding ...
But centipedes have all their body segments already in place at birth, according to the study authors. This finding suggests that Arthropleura attained peak segmentation as an adult, rather than ...
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).
Size-wise, centipedes are smaller and have slender bodies, while millipedes are longer and have plumper bodies. This also applies to their legs, with centipedes having longer legs than millipedes. 3.
The species is between 18 and 30 mm long and up to 4 mm broad and is a chestnut brown coloration. It is similar to a variety of other European lithobiid centipedes, particularly the striped centipede, Lithobius variegatus, but L. forficatus does not have stripes on its legs.
