(Gray, 1839)[2]

Olivella semistriata is a species of small sea snail, a marine gastropod mollusk in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives[3] With the very similar Olivella columellaris it forms the subgenus Pachyoliva.[4] Both species are suspension feeders. They use unique appendages of the propodium (front part of the foot) to deploy mucus nets which capture suspended particles from the backwash on sandy beaches of the tropical eastern Pacific.[1] Olivella semistriata is a swash-surfer; the snails use their expanded foot as an underwater sail to follow the tidal movement of the backwash zone in which they feed.[1]
