The arthropod group Chelicerata includes animals as diverse as spiders, scorpions, mites, ticks and horseshoe crabs. In addition to these well-known living animals, it includes important extinct groups such as the eurypterids (sea "scorpions").
This review analyses the mechanisms of neurogenesis, the morphology of serotonergic interneurons, the number of motoneurons, and cellular features and development of the lateral eyes of Chelicerata.
The 75000 species within this subphylum belong to three diverse classes. The Classes Merostomata and Pycnogonida include relatively minor, aquatic organisms, the Class Arachnida comprises the vast majority of species (74000 + ) and includes spiders, scorpions, mites and ticks.
