Myriapods have a single pair of antennae and, in most cases, simple eyes. Exceptions are the two classes symphylans and pauropods, and the millipede order Polydesmida and the centipede order Geophilomorpha, which are all eyeless. [10] The house centipedes on the other hand, have large and well-developed compound eyes. [11]
There are many differences between millipedes and centipedes. [9] Both groups of myriapods have long, multi-segmented bodies, many legs, a single pair of antennae, and the presence of postantennal organs. Centipedes have one pair of legs per segment, while millipedes have two.

Lhéritier is pursuing his doctorate in ancient myriapods, an arthropod group that includes millipedes and centipedes, at France’s Claude Bernard University Lyon 1 to understand how arthropods ...
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 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.
[19] [20] The species with 12 pairs are the only myriapods with actual legs on the first body segment, as the first pair of legs is modified into forcipules in centipedes, and in pauropods the segment is a reduced collum which bears ventrally a pair of small papillae, while in millipedes it's a collum without any appendages at all. [21]
Mandibulates include the crustaceans, myriapods (centipedes and millipedes), and all true insects. 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.
