Shell of the Week: The Two-band Eulima


Eulima bifasciata d’Orbigny, 1841 is a super-slender member of the family Eulimidae. Eulimids are snails that parasitize the external or internal parts of echinoderms such as sea cucumbers and sea urchins, basically sucking their blood for a living. Two-band Eulimas may reach 10 mm (a little less than 0.5 inch), have a very glossy shell with slightly convex whorl outlines, and a very pointed apex. Two golden-brown bands just below the suture (the groove separating two whorls) are characteristic of this species.
