Lampasopsis rhodostoma (Sowerby, 1835)
27mm

Lampasopsis rhodostoma is very common in the Marshalls, living in a variety of reef habitats, usually under rocks or in lagoon algae patches at depths of 1 to 20m.

The one below was found eating an Echinothrix urchin.

The one below appeared to be depositing its dark-colored egg mass inside the shell of an old dead bivalve. We did not actually see it producing the eggs.

Two more from lagoon algae patches.

The specimen below was unusually large at 35.1mm but the shell shape with limited posterior canal development matches Lampasopsis rhodostoma.
