Population structure of the deep sea hermit-crab Catapaguroides microps (Paguroidea, Anomura) in the Campos Basin, RJ, Brazil

The population of Catapaguroides microps A. Milne-Edwards and Bouvier, 1892 in the Campos Basin was studied with an emphasis on its composition in the Northern and Southern parts of the Basin, the different gender sizes, sex ratio, and size class distribution. Specimens were collected under the &quo...
