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.
