Chelicerata is the group of arthropods that includes the marine sea-spiders and horseshoe crabs and the terrestrial arachnids (spiders, mites, scorpions and their relatives). They have two main body regions, and the arachnids typically have eight walking legs. They are covered by a jointed exoskeleton and grow by periodic moulting. Chelicerates are typically predaceous and most terrestrial forms ingest only liquefied food. Next to insects, they are the most diverse and numerous animals… Expand

Holocentric chromosomes: from tolerance to fragmentation to colonization of the land
TLDR
It is argued that the tolerance to clastogens explains the origin of Holocentric lineages and may also have far-reaching consequences for eukaryotic evolution in general as exemplified by the potential role of holocentric chromosomes in terrestrialization. Expand

TLDR
A cladistic analysis of the 11 Recent arachnid orders suggests that Arachnida is monophyletic and composed of two principal lineages, Micrura and Dromopoda. Expand
