The Brown Eulima
The Brown Eulima, Microeulima hemphilli (Dall, 1884), is a slender gastropod of the family Eulimidae. Eulimidae 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. The Brown Eulima reaches about 5 mm (0.2 inch), and has a teardrop-shaped aperture, and smooth, brownish, slightly translucent shell. The shell in the images was collected by Phyllis Sharp on Sanibel in 2014.
