Like its ancestor, the Centilixo digs around the seafloor to scavenge for food. It has a pair of chitinous beak-jaws which it uses to break up larger pieces of food into something it can swallow, and melter detritis in its gut help it to break down crystal flora. It now mainly uses the upper pair of tentacles for digging, and they have gained chitinous claws that help with this; the lower pair remains unclawed and mainly manipulates food while it is eating, preventing pieces from easily falling out of reach.
Like its ancestor, the Centilixo communicates with others of its kind with bioluminescent spots that can be switched on and off. It is sexually dimorphic, with males having brighter spots than females. Mated pairs mate multiple times over the course of several weeks, with the female laying as many as 5000 eggs every few days. Though not the most intelligent organism, it is smart enough to interpret a variety of different signals from others of its kind. It is generally social and commonly found in small groups of 3-5 individuals.
