=== Evolution ===
It is theorised that the Invenid evolved from a subterranean ambush predator; the Invenid would dig into the ground and lie in wait for prey, before leaping out to catch it. Their low metabolisms would allow one Invenid to catch a meal for a family group, and the ingenuity in catching prey in this fashion, and outsmarting those who could escape them, led to the evolution of intelligence; the low need for food allowed group family units to form, which in turn led to them becoming social creatures.
