While some litusfoi evolved magnetite needles to serve as a defense against predators, others took to making themselves larger. The braided litusfoi achieves this by forming slug shaped colonies. These colonies move by undulating their digestive membranes in unison. Their movement is coordinated with the use of hormones, which are relayed from cell to cell. They will consume anything they can cover with their digestive membranes. If attacked by a predator, the colony can break apart, with its components fleeing in all directions. Surviving individuals can then form new colonies. Colonies grow by adding new isomers, which in turn originate from the cell on the posterior of the colony. If a colony grows too large, the cell on the anterior will split off and form a new colony if it survives long enough.
