Murex snails are no longer used as dyes because this use led to over harvesting and near extinction of the species. A synthetic dye that is close to the original color of the snail dye is now used instead.

A species of tropical marine snail belonging to the Murex genus, or more specifically the Murex brandaris and Murex trunculus sp., more commonly referred to simply as the Murex, as by Aristotle, used to used to make 'Tyrian Purple' dye.
The term murex is used to refer to a medium - large sized tropical sea snail. These snails are carnivorous marine molluscs. They are also often refered to as 'rock snails'.
Murex is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod nolluscs in the family Muricidae, the murexes or rock snails. The common name "murex" is also used for a large number of species in the family Muricidae, most of which in the past were originally given the Latin generic name Murex, but most of which have now been grouped in other newer genera.

Murex dye :)
The snails made a rich purple dye, which was used for clothing
The Phoenicians discovered that crushed shellfish( the specific shellfish is the murex) oozed a fabulous wine-colored goop. Cloth soaked in this substance turned shades ranging from deep pink to rich purple. Royalty soon chose purple as their favorite hue, so every king and queen needed purple dye!
Costly and labor-intensive dyes Tyrian purple (or royal purple) and Tekhelet were historically made by the ancient Phoenicians using mucous from the hypobranchial gland of two species commonly referred to as "murex", Murex brandaris and Murex trunculus, which are the older names for Haustellum brandaris and the Hexaplex trunculus.This dye was used in royal robes, other kinds of special ceremonial or ritual garments, or garments indicating high rank. It featured prominently in the ancient Temple in Jerusalem, the clothing of the High Priest (or Kohen Gadol) officiating there; it is sometimes still used by Jews today in the ritual fringes (tzitzit) on four-cornered garments.--from Wikipedia (subject: murex)
There are different types of snails that could be used for racing. The largest snails often get used and weigh between 1 to 2 pounds at most.
To see.
we eat them as FOOD
I used to have snails with my goldfish and they got along swimmingly!
