The queen conch is grey with long eyestalks and a large tube-like mouth that is known as a proboscis. Its shell is pinkish on the inside and orangish on the exterior, which is usually covered with algae and debris. This species normally grows to between 6 and 9 inches, but has been known to reach as large as 12 inches. The queen conch is found in sea grass beds and on sand flats at depths between 3 and 100 feet.
