Linkedgrabeneresca has made two developments, first it now lives in a colony, and secondly it has a way to kill its prey now: it uses its large hands to crush the prey until it is dead, and then phagocytosizes it, nutrients are shared in a limited fashion by the members of the colony which is maintained to always have 4 members, with excess members being kicked out and missing members replaced by rapid mitosis of the fittest individual next to the empty spot.
