Info

Annulobalcis yamamotoi T. Habe, 1974

Eulimidae is a family of very small parasitic sea snails. These small parasitic snails live on (or in some cases in) the bodies of echinoderms such as sea cucumbers, sea urchins, sea stars, etc. All species lack a radula, in most cases possessing a proboscis which they extend into their host's body cavity in order to feed their blood.
