Olivella riverae is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives. [2]
"Shell of medium size (length about 12 mm.), relatively thin, spindle-shaped, with an elevated spire of about 5 whorls, the body-whorl large, subelliptical. The parietal callus is developed as a thin enamel spread along the inner lip of the aperture and passing above the end of the aperture but spread so lightly that it does not obscure the color of the penultimate whorl beneath. Pillar structure weak, forming a low ridge along the columella, finely lirate below. Aperture effuse in front, the notch of the siphonal canal wide, the outer lip thin. Color is a mottled brown or rich mahogany formed by the coalescence of small blotches of color on a gray-yellow base which at the suture form into short, crooked lines. Fasciole is similarly colored brown, the upper band yellow, with brown spots. Aperture has the parietal callus often white, the interior of outer lip a deep brown. Length 12.7 mm., diameter 5.1 mm.".

Olivella, common name the dwarf olives, is a genus of small predatory sea snails, marine gastropod molluscs in the subfamily Olivellinae of the family Olividae, the olives. Olivella is the type genus of the family.
Crassopleura maravignae is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. It is the only known species within the genus Crassopleura.
Turbo imperialis is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.
Turbo heterocheilus is a species of sea snail, marine gastropod mollusk in the family Turbinidae.
Olivella bitleri is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella columellaris is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives. With the very similar Olivella semistriata it forms the subgenus Pachyoliva. Both species are suspension feeders. They use unique appendages of the propodium to deploy mucus nets which capture suspended particles from the backwash on sandy beaches of the tropical eastern Pacific.
Olivella drangai is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella lactea is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella moorei is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella perplexa is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella rehderi is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
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 With the very similar Olivella columellaris it forms the subgenus Pachyoliva. Both species are suspension feeders. They use unique appendages of the propodium to deploy mucus nets which capture suspended particles from the backwash on sandy beaches of the tropical eastern Pacific. 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.
Olivella thompsoni is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
Olivella watermani is a species of small sea snail, marine gastropod mollusk in the subfamily Olivellinae, in the family Olividae, the olives. Species in the genus Olivella are commonly called dwarf olives.
