on a galactic scale
The most notable feature shared by all Insids is that they have done away with manual labour and all their work is done by robots. Insids live in buildings called cots, from which they control the robots.
Insids have developed their own system of species classification, consisting of an order (animal, plant, mineral), a form, a kind and a variety. Insids classify themselves as animal/vertebrate/plud/insid.
Insids evolved on the planet Tifthint, where most of them still live. they evolved from a much stronger Plud, which evolved to be weaker after they completely automated their society, so as to decrease the nutrients they required and allow them to put more nutrients into larger brains and reproduction.
Insids have a single weak arm with numerous fingers on the front of their body. They have two eyes and move short distances by crawling.
