Parasitism of monogamus minibulla (Olsson and McGinty, 1958) (Gastropoda: Eulimidae) on the red sea-urchin echinometra lucunter (Linnaeus, 1758) (Echinodermata: Echinometridae) on the Caribbean coast of Mexico

Eulimids are gastropod mollusks parasites of echinoderms. Intertidal red sea-urchins, Echinometra lucunter, collected along the Mexican Caribbean shores were examined for the presence of those ectoparasitic gastropods. The analysis of 206 seaurchins resulted in 56 having eulimids on them (27% prevalence), mostly living in pairs, with about 7 eulimid pairs per sea-urchin. The eulimid gastropods found are Monogamus minibulla (Olsson and MacGinty, 1958), described from Panama. Its host was unknown. This article consists of the first record of this host-parasite relationship. A short description of the shell structure and some details of the biological relationship are given. The females are much larger than the males, and the latter are usually attached to the female bodies. Most female eulimids live inside the hypertrophied foot, which this allows for partial enveloping of the entire body.

A few females, however, were found living fixed directly on the echinoderm integument. The position of the gastropod on the sea-urchin is fixed via boring through the skeleton. Anchoring is achieved via the proboscis. Some females had egg capsules (0.9-1.5 mm) fixed to their bodies; each is a spherical structure attached to the body by a short stalk. Egg capsules contained 14-15 embryos in different stages of development. The only previously published account of this type of relationship involves a similar species living on Echinometra mathaei (Blainville, 1825) from the Red Sea.
