Host selection by Dissodactylus crinitichelis and Clypeasterophilus rugatus for different echinoderms was investigated. Initial preference (within 24 h of collection) and preference after "conditioning" with an alternate host were compared. D. crinitichelis

This paper presents the first report on the association between Dissodactylus crinitichelis Moreira, 1901 and Mellita quinquiesperforata (Leske, 1778) based on specimens found in Brazilian waters. Eighty-two specimens of sand dollars were collected and

The ability of chemical recognition is important for marine invertebrates to detect if host conditions (such as stress) are suitable for colonisation, and the presence of conspecifics can also be important for host switching. We investigated whether Dissodactylus
