Extract

Many pycnogonids are ectoparasites of benthic invertebrates. Even gastropods are on their menu (reviewed in Dietz et al. 2018). It is somewhat ironic that a marine gastropod, Dickdellia labioflecta (Dell, 1990), might have reversed this principle. Hedgpeth (1964), Sirenko (2000) and Schiaparelli et al. (2008) observed clutches of eggs and young Dickdellia snails on pycnogonids. Sirenko (2000) suggested that this might be a case of ectoparasitism and not just phoresy.
