Shell description

The

suture
extends outward and then at a sharp shoulder drops into the suture.

The shell coloration can vary from cream to a greyish exterior with reddish-brown zigzag markings. The common name of this species is derived from the darker surface markings that sometimes resemble letters.

Life habits

Like all olives, the lettered olive is a

bivalves and small crustaceans with its foot and takes them below the sand surface to digest.[7]

Its presence is sometimes detected at very low tides by the trails it leaves when it crawls below the surface on semi-exposed sand flats.[7]

Females lay floating, round egg capsules that are often found in beach drift. Young are free swimming.[7]

Human use

Colonists and early Native Americans made jewelry from these shells.[7]

The lettered olive is the state shell of South Carolina.[7]
