King crabs up-close: ontogenetic changes in ornamentation in the family Lithodidae (Decapoda: Anomura), with a focus on the genus Paralomis
In this study, we describe the carapace ornamentation found on species of Lithodidae (Decapoda: Anomura), focussing primarily on the genus Paralomis, which displays the greatest diversity of forms, globally. Evidence of ontogenetic change in the surface ornamentation of lithodids has previously been highlighted for one species of Paralomis (P. granulosa Jaquinot), however its wider occurrence within the family has never been formally examined. Growth-related change in dorsal spines and tubercles was considered, using growth-series from 8 species of Paralomis (P. mendagnai – South Pacific; P. multispina – N. Pacific; P. spinosissima, P. granulosa – South Atlantic; P. inca – South East Pacific; P. erinacea – East Atlantic; P. cubensis – Caribbean; P. stella – Southern Indian Ocean). Tubercular structures from adult specimens of 24 additional species of Paralomis are figured (Figs 10-17) in order to provide a reference for future diagnosis. This study shows that ontogenetic changes should be considered when identifying specimens of Lithodidae to species level.

Abstract

In this study, we describe the carapace ornamentation found on species of Lithodidae (Decapoda: Anomura), focussing primarily on the genus Paralomis, which displays the greatest diversity of forms, globally. Evidence of ontogenetic change in the surface ornamentation of lithodids has previously been highlighted for one species of Paralomis (P. granulosa Jaquinot), however its wider occurrence within the family has never been formally examined. Growth-related change in dorsal spines and tubercles was considered, using growth-series from 8 species of Paralomis (P. mendagnai – South Pacific; P. multispina – N. Pacific; P. spinosissima, P. granulosa – South Atlantic; P. inca – South East Pacific; P. erinacea – East Atlantic; P. cubensis – Caribbean; P. stella – Southern Indian Ocean). Tubercular structures from adult specimens of 24 additional species of Paralomis are figured (Figs 10-17) in order to provide a reference for future diagnosis. This study shows that ontogenetic changes should be considered when identifying specimens of Lithodidae to species level.
