Splitting from its ancestor, necrotic arrowhead now lives in the darkness of the abyss, growing large in the cold depths. They begin life as small spores resembling the mobile forms of their ancestor and are simple detrivores. Within a week they find a suitable place to live and transform into barnacle-like growths. They then rapidly mature into their adult forms which are permanently held in place by their solidified tail. Swaying gently, they unleash a flurry of mouth tentacles and wait for something to come into contact with them. Once they do, innumerable nematocysts spear it and then drag it back into its mouth. Once engulfed, the paralyzed prey is then grounded up in an organ at the base of its mouth filled with tooth-like spikes.
Their bioelectric patches are used for by them in order to sense when potential prey is approaching them, that way they can keep their feeding tentacles tucked deep within their body when not in use. They are fully capable of bending over in order to snatch up fauna that crawl near them. They release their spores from the base of their head.
Their duel brain system, while apparent in its larval stage, degrades as it reaches adulthood. While both brains are still present, they have simplified in order to compliment this organisms life style, such as feeding, reproducing, and controlling its bioelectric sensing organ.
