In the classification of the Animal Kingdom, the Crustacea form one of the divisions of a comprehensive group, or Phylum, known as Arthropoda.

Sea cucumbers are echinoderms, marine animals in the same phylum as sea urchins, starfish, and sand dollars.
In science, categories matter: phylum, family, class, species, solid, liquid, endo-, exo-, we analyze by creating groups, by making clean distinctions.

Possible Implications of the Quantum Theory of Gravity
In Ap 05 I reported on a possible new phylum of the Archaea represented by the sole hyperthermophilic symbiont/parasitic species Nanoarchaeum equitans37 (Huber et al. 2002), which cannot be cultivated independently of its host. I quoted a linear size of 150 nm.
