Conch shells typically have a high spire and a noticeable siphonal canal (in other words, the shell comes to a noticeable point on both ends). Conches that are sometimes referred to as "true conches" are marine gastropods in the family Strombidae , specifically in the genus Strombus and other closely related genera.

South Florida bands (such as the Tequesta), the Carib, the Arawak and Taíno used conch shells to fabricate tools (such as knives, axe heads and chisels), jewelry, cookware and used them as blowing horns.
This notch is where one of the two eye stalks protrudes from the shell. The true conch has a foot ending in a pointed, sickle-shaped, operculum, which can be dug into the substrate as part of an unusual "leaping" locomotion. True conches grow a flared lip on their shells only upon reaching sexual maturity. This is called an alated outer lip or ...
The shell margin has an indentation near the anterior end which accommodates one of the eye stalks. This indentation is called a strombid or stromboid notch. The stromboid notch may be more or less conspicuous, depending on the species. [7] The shells of most species in this family grow a flared lip upon reaching sexual maturity.
Varieties of Valampuri shells are defined by their locality. The three main localities are Rameshwar, Ram Setu, and Sri Lanka. The second is West Coast of India or Arabian Sea and the third is Bay of Bengal. All three types show variation. Real Lakshmi Conch (right side spinning) are estimated to occur once per 100,000 conch shells.

There are two forms of the shanka: a more common form that is "right-turning" or dextral in pattern, and a very rarely encountered form of reverse coiling or "left-turning" or sinistral. [9]
