The jujubee darkswarmer has replaced its ancestor, the dark swarmer, in Jujubee Ocean (Sea Floor) and Jujubee Ocean (Abyss Zone). It has grown to ten times its ancestor's size, and evolved two proto-eyes on its sides. It uses these eyes not to see light, but rather to feel differences in water pressures around it. It has lost its bio-luminescent cells at the ends of its tentacles, and now it is less noticeable to predators.
Except for a few patches of green photosynthesizing skin cells, the majority of the jujubee darkswarmer's skin is blue and teal colored. Its digestive tracks elongated and forms a cone inside its body. This, in turn, compresses the water that transfer through the digestive filtering membrane, and releases them in a strong jet of liquid at the back end of the darkswarmer, making it move faster through the waters
