What does «murex» mean?

murex is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod molluscs in the family Muriciadae, commonly called «murexes» or «rock snails». While searching for a company name, we accidentally came across this word - and we just loved it. It was important to us to find a name for our newly founded company that is short and concise. And it had to be easy to pronounce in all the languages of our target markets.
