arthropod
Let an agent explain arthropods and their major groups, describe their biology and roles in ecosystems and human life, support identification at group level, and describe their significance as pests, vectors and resources.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain arthropods and their major groups, describe their biology and roles in ecosystems and human life, support identification at group level, and describe their significance as pests, vectors and resources.
An invertebrate animal of the phylum Arthropoda, with a segmented body, jointed limbs and a chitinous exoskeleton that is moulted to grow, comprising insects and other hexapods, arachnids, crustaceans and myriapods, and forming the most diverse animal phylum; arthropods include pollinators, decomposers, pests, disease vectors, invasive species and food sources, and are studied in entomology, arachnology and carcinology.
What it is for: Jointed-limbed invertebrates.
It can be explain major groups; describe biology and roles; support identification; describe significance.
