Rowden & Jones (1994) estimated that Callianassa subterranea could achieve a carapace length of 6.5 mm by the end of the first year. They noted that other estimates were similar and cited growth estimates of 6 mm, 8 mm and 9.5 mm in carapace length in the first year.
The bopyrid isopod Ione thoracica resides in the branchial chamber beneath the carapace of Callianassa subterranea. A significant enlargement of the carapace allows for easy identification of those individuals suffering from such parasitism. Potential effects of bopyrid infestation are the prevention or reduction of maturation of eggs in females and reduction of testes and slenderization of the primary chelae in males (Rowden & Jones, 1994).
