There are quite a few of these conches here in Cozumel. Conchs are herbivores—they eat algae and other tiny marine plants. Did you know it may take a queen conch at least 5 years to reach maturity? They grow up to a maximum of 12 inches long and 5 pounds. Too many of these beautiful shells are taken from the sea to make souvenirs. Please leave all shells in the sea where they belong. They are shelters for many sea creatures and we disturb the ecosystem when we do so. #scubadiving #scubadivingmag
