Comment(s) on data
Faxon (1896: 155) - Lives as a commensal in Sponges of the genus Farrea. - Bouvier (1925: 462) 'Une des femelles habite la cavité d'une éponge siliceuse'.
Concerning E. rotundifrons, affiliated to E. caribbaeus, Bouvier (1925: 464) indicates 'Je regardai d'abord cette variété comme une espèce distincte que je désignai sous le nom d'E. rotundifrons; mais une étude comparative de nombreux exemplaires montre avec une parfaite évidence qu'il s'agit seulement d'une variation un peu particulière de l'E. caribbaeus'.
Eiconaxius Bate, 1888 is a genus of axiid shrimps exclusively associated with deepsea hexactinellid sponges
