Sucker Foi

Splitting from its ancestor, the sucker foi has developed a parasitic life-style in order to survive in the depleted oceans. It begins life as microscopic spores that drift until they come in contact with a suitable host. Once they have latched upon the skin, they form a small cyst and go into a form of hibernation. After several days they hatch and then begin to feed. Holding onto the flesh of their host, the sucker foi has no need for "fins" and has lost them, and instead has almost root-like growths on its belly that both hold it in place and feed off the hosts blood supply. They are rather indifferent to the blood type of their host, and truly only care about how many nutrients they can leach from it. Massive infestations are now a rather common site, though they rarely, if ever prove fatal and instead merely cause extreme irritation and occasional weakness due to blood loss.
