1 Larvae. 2  Early in development, most crustaceans go through a series of larval stages, the first being the nauplius larva, in which only a few limbs are present, near the front on the body; crustaceans add their more posterior limbs as they grow and develop further. 3  The nauplius larva is unique to Crustacea.rustaceans can also be found on land; the most familiar are probably pillbugs or woodlice, which are a type of isopod. (Not every organism with âbugâ in its name is an insect.). Most crustaceans live in the ocean, and are one of the pillars of the global marine ecosystem.
