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.
Both groups of myriapods share similarities, such as long, multi-segmented bodies, many legs, a single pair of antennae, and the presence of postantennal organs, but have many differences and distinct evolutionary histories, as the most recent common ancestor of centipedes and millipedes lived around 450 to 475 million years ago in the Silurian ...
The cyanide secretions are not dangerous to humans, but can cause irritation and pain if it contacts sensitive areas such as the mouth, eyes, or nose. Despite the various common names given the species, the coloration pattern, cyanide defense, and associated almond scent occur in other flat-backed millipedes around the world.

Scutigera coleoptrata, also known as the house centipede, is a species of centipede that is typically yellowish-grey and has up to 15 pairs of long legs. Originating in the Mediterranean region, it has spread to other parts of the world, where it can live in human homes. [1]
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 ...
S. heros is found in northern Mexico and the southwestern United States, from New Mexico and Arizona in the west to Arkansas, Missouri, and Louisiana in the east. Although this species is commonly referred to as the "giant desert centipede" because of its presence in the Sonoran and Chihuahuan Deserts, and other arid and semi-arid habitats, S. heros is also found in rocky woodland areas, such ...
The stalked eyes - like a crab's - are striking because no living members of the group of arthropods that includes millipedes and centipedes - called myriapods - have this kind of eye.
