Echinolittorina placida
Echinolittorina placida is a species of sea snail, a marine gastropod mollusc in the family Littorinidae, the winkles. This species was not described until 2009 because it had previously been confused with, and not differentiated from, a similar-looking species, Echinolittorina interrupta.
