Describing an organism that lacks the characteristics of arthropods, especially jointed limbs; non-arthropod.
From Greek 'an-' (not) + 'arthropod' + the adjectival suffix '-ous,' following Linnaean terminology patterns. This term appears in obsolete biological descriptions.
This awkward adjective shows how scientific language can get tangled when scientists are trying to be precise—saying something is 'anarthropodous' is like saying it's 'not-arthropod-ish,' and it's exactly the kind of term that gets cleaned up as fields develop better classification systems.
