Any of a very large and diverse phylum of Terragen or Terragen-derived metazoa with segmented bodies, jointed limbs, and exoskeletons made of chitin.
Insects, arachnids, crustaceans, myriapods, trilobites, eurypterids, arthropleurids, and Vedokikleks are among a few of the countless millions of kinds of arthropods that have lived in the past or are still alive today. Although most arthropods are small, a few prehistoric and lazurogenic kinds can reach one to two meters in length, and several augmented and geneered forms have been modified to attain many times that size, albeit in low gravity environments.
Although true arthropods are Terragen only, there are many examples of arthropodoidal animals with superficially similar body-structure (albeit different chemistry, metabolism, and anatomy) evolving on a number of worlds. In addition, many hardcopy alifes and neumanns have found the arthropoic form to be the most optimal morphotype for deep space exploration and replication.
- Arachnid - Text by Stephen Inniss
A class of Old Earth arthropods. Among other common characteristics they have eight legs, a pair of appendages legs that serve as mouth parts called chelicerae, and an additional pair of appendages called pedipalps that may serve for feeding, locomotion, or reproduction depending on the species. Arthropods include spiders, scorpions, mites, ticks, and whip scorpions. Most are detritivores, parasites, or predators. Before the Great Dying there were over 100,000 species. Records of many of the originals were preserved by the Burning Library Project, and it is believed that GAIA has lazurogened many or all of the ancient varieties. Arachnids are common to in almost any Terragen-derived biosystem, if only as soil organisms. Non-sophont splices such as space spiders and bucky spiders are fairly common. Spider provolves and rianths are quite rare, but the Imtonasi are a fairly widespread clade.
