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]
Myriapodology is the scientific study of myriapods which includes centipedes and millipedes. The field of myriapodology can also cover other myriapods such as pauropods and symphylans. Those who study myriapods are myriapodologists. [1]
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 ...
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 ...
Most myriapods have paired lateral spiracles similar to those of insects. Scutigeromorph centipedes are an exception, having unpaired, non-closable spiracles at the posterior edges of tergites. [2] Velvet worms have tiny spiracles scattered over the surface of the body and linked to unbranched tracheae.
In general, arthropods have mouthparts for cutting, chewing, piercing, sucking, shredding, siphoning, and filtering. This article outlines the basic elements of four arthropod groups: insects, myriapods, crustaceans and chelicerates. Insects are used as the model, with the novel mouthparts of the other groups introduced in turn.
Within the myriapods, centipedes are believed to be the first of the extant classes to branch from the last common ancestor. The five orders of centipedes are: Craterostigmomorpha, Geophilomorpha, Lithobiomorpha, Scolopendromorpha, and Scutigeromorpha. These orders are united into the clade Chilopoda by the following synapomorphies: [57]
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.
