Oliva incrassata, the angled olive or giant olive, is a species of sea snail, a marine gastropod mollusk in the family Olividae, the olives.^[2]

Distribution

[edit]

This species is widespread from California to Peru.^[3]

Habitat

[edit]

These sea snails live at the low-tide level, at the outer side of sandspits.^[4]

Description

[edit]

Shells of Oliva incrassata can reach a length of 32–95 millimetres (1.3–3.7 in).^[3] These relatively large shells are almost cylindrical, very thick, ovate, angularly swollen in the middle, with a rather short spire, a narrow and long aperture and usually with uniformly colored body whorls, except in the colummellar area. The basic color background may vary from ash-white or greyish to light yellow and brown, mottled with gray and olive, with angled transverse dark chestnut streaks and a fleshy rosy pink columellar area.^[4]^[5]

Biology

[edit]

The Giant Olives are active predators. At night they search for food, while during the day they bury themselves beneath the sand and mud.
