Like its closest relative, Arachnea parapluviosis triDeïs, Arachnea parapluviosis triDrinoidea has yet to be given an English name. However, in terms of lifestyle, it resembles Arachnea parapluviosis crinoidea, the lily spider of the seas. While the lily spider of the seas is noted for its elegance, Arachnea parapluviosis triDrinoidea is distinguished by its rather bulky appearance. Its body consists of plastic spheres with cavities designed to house Halomonas titanicae bacteria. Using their tentacles, they sift metal particles from the water. They also undergo gradual metallization as the bacteria extract energy from the metal, but the resulting appearance is more akin to manganese nodules. There is also a hypothesis similar to that of Arachnea parapluviosis crinoidea that Arachnea parapluviosis triDrinoidea, seeking to escape its grim fate, abandoned its sessile existence, broke free from its marine habitat, and eventually ventured onto land.
