In contrast to their overwhelming genetic diversity, all known virus isolates display a limited number of morphotypes. It has been suggested that due to structural constraints and limitations in protein fold space, virus morphological diversity is restricted to certain possible architectures. Thus, the huge and complex virosphere can be ordered by grouping viruses into
