Lapiroids are strange, space borne creatures. They form hard shells and attach themselves to the hulls of spacecraft in order to migrate from planet to planet. The shells are hard enough to withstand the extreme heat of planet fall. Once planet side the creatures enter a mating stage, where they develop limited mobility. Lapiroids have been known to chew through space craft hulls to suck energy from the systems within. Extensive infestations have been known to cripple entire commercial and military fleets.
