Coral Snails Rarity: Uncommon Description: Coral snails range from very small, say the height of a coin, to as large as an elephant. They take coral on their back at a young age and it grows as time goes on. Most take on a shell of a pinkish, but hard, coral that allows for other corals to float by and attach themselves to its surface for a symbiotic relationship. They are gentle creatures that roam around coral reefs searching for food and softer variants of coral. Many have grown horns of coral to fight each other over a mate or to defend against the predators from the surrounding ocean.
