Just a matter of size? Evaluating allometry and intersexual heterometry in Pagurus bernhardus using ratios and indices (Decapoda, Anomura)

Integrative Zoology, Volume 19, Issue 5, Page 807-823, September 2024.
We analyzed 190 specimens of the common European hermit crab species Pagurus bernhardus to look for the heterometry between the sexes regardless of the body size. We calculated three different indices and found all to be significantly different between males and females, indicating that males have bigger major and minor chelipeds than females, even if ...
