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.
Conch (US: / k ɒ ŋ k / konk, UK: / k ɒ n tʃ / kontch [1]), or conque, also known as a "seashell horn" or "shell trumpet", is a wind instrument that is made from a conch, the shell of several different kinds of sea snails.

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]
In a new study, published May 2 in the journal Antiquity, researchers examine how sound traveled across the desert landscape and how conch shells may have been used as a way to bring communities ...
The larval shell may have a completely different mineralogy to the adult conch, perhaps formed from amorphous calcite as opposed to an aragonite adult conch. [ 4 ] In those shelled molluscs that have indeterminate growth , the shell grows steadily over the lifetime of the mollusc by the addition of calcium carbonate to the leading edge or opening.
Marine diatoms form hard silicate shells. Plant-like diatoms and animal-like radiolarians are two forms of plankton which form hard silicate shells. Foraminifera and coccolithophores create shells known as "tests" which are made of calcium carbonate. These shells and tests are usually microscopic in size, though in the case of foraminifera ...
Florida’s marine life attracts people from all over the world — but what happens if someone gets too comfortable with the state’s natural wonders?
Real Lakshmi Conch (right side spinning) are estimated to occur once per 100,000 conch shells. The shell of the lightning whelk almost always opens on the right (when viewed with the siphonal canal pointing upwards). Valampuries with five plaits or folds in its cavity are known as 'Panchajanya' and are rare.
