With its unique anatomy, a Queen Conch looks quite a fascinating animal. With a solid, thick beige/sandy-colored spiraled shell that comes with spikes on the shoulder, and a glossy pink or orange aperture, the Queen Conch (Strombus gigas) is a marine mollusk. Until recently, it was also known as Lobatus gigas. In 2020, it was renamed, and today the Queen Conch scientific name as per the World Register of Marine Species is Aliger gigas.

The exterior color of the shell is such that it helps it blend with the environment and saves the conchs from predators. Inside the conch shell is the soft body of the animal that is edible. The Queen Conch meat is consumed in the Caribbean countries as a delicacy. An adult conch typically weighs around 5 lb. The thicker the flare of the conch, the older it is. In this article, we share some fascinating facts about the Queen Conch, so do check them out.

Queen Conch Interesting Facts

What type of animal is a queen conch?

The Queen Conch (Strombus gigas) belongs to the family of true conches and is a large gastropod mollusk. It falls in the same taxonomic group as squids, oysters, clams, and octopus. The mollusk has an average age of 30 years, and it reaches its maximum length of about 12 inches in about five years. After that, it doesn't grow bigger as it ages, but the shell keeps on getting thicker.

What class of animal does a queen conch belong to?

A Queen Conch belongs to the class Gastropoda, order Littorinimorpha, and family Strombidae.

How many queen conchs are there in the world?

Since these conchs live on the ocean floor, it is impossible to estimate the world's Queen Conchs population accurately. But since this marine mollusk is a prized animal for both its shell and meat, it is overexploited through fishing in many coastal regions leading to a steep decline in its population. Such a decline is seen as a threat to marine biodiversity and has led to many marine parks where fishing is controlled or prohibited.

Where does a queen conch live?

It is typically found in shallow tropical waters. It lives in the coral reef ecosystem and seagrass beds and sand flats. The conch species flourish in various types of habitat in the Caribbean coast, Florida Keys, South America, and the Gulf of Mexico.

What is a queen conch's habitat?

It lives in seagrass beds, sand flats, and the coral reef ecosystem. Depending on the depth of its habitat and the availability of aquatic vegetation, there are slight variations in its shell morphology, shape, length, and spike patterns.

Who do queen conchs live with?

Queen Conchs are primarily social animals. With its shell and soft body, the Lobatus gigas share a commensal relationship with many other animals. Commensalism is a symbiotic biological relationship in which one species benefit while the other is neutral, i.e. neither benefitting nor being harmed. Animals like the porcelain crabs, a type of cardinalfish called Conch fish, and Slipper snails are some animals that take shelter in the live queen conch's shell.

How long does a queen conch live?

The average life of a Queen Conch is about 20-30 years. Some living in protected marine parks and deep-sea waters are known to live as long as 40 years.

How do they reproduce?

Queen Conches are sexually mature at about three to four years of age when their lips are completely flared. Reproduction happens in Queen Conches through internal fertilization. Massive egg spawning aggregations are formed by the Queen Conches during the breeding season, starting from March till October. The female lays about nine egg mass each season that are fertilized by multiple males, and each egg mass comprises about 180,000-460,000 eggs. The eggs stick in gelatinous strands that can be 75 ft long and lie on sand beds. The eggs are covered by sand grains, and it acts as camouflage to save them from predators. After an incubation period of three to five days, the eggs hatch, and the larvae drift with the water currents and join the phytoplankton. After 16-40 days of hatching from the eggs, they metamorph into tiny conches and live as benthic animals. As they grow, the shells grow harder and thicker, forming a protective layer over their soft bodies.

What is their conservation status?

The Queen Conch is not evaluated for its conservation status by the IUCN. While it is not endangered in the Caribbean Sea, its population is under threat in many areas due to overfishing for conch meat and shells. CITES has listed it in Appendix II, which means that it is not an endangered species right now, but it could be if there are no proper trade controls put in place.

Queen Conch Fun Facts

What do queen conchs look like?

The Queen Conch anatomy is similar to other snails. Inside the conch shell is a soft body that consists of its head, the foot, and the visceral body. The body is characterized by a slender snout, long eyestalks with Queen Conch eyes, a tubular mouth called a proboscis, crescent operculum, tentacles for a sense of smell and touch, and a tiny foot that helps it hop in the water. When threatened, it can put its body inside the shell for safety from predators. The shell of the adult animal is thick and heavy with a glossy pink or orange aperture and spines on the shoulder. The juvenile conches do not have a flared lip; it gets it at about four years of age when it gets sexually mature.
