Scallops

5 species

Scallops are fascinating bivalve mollusks that can make intriguing additions to a marine aquarium, though they are not commonly kept due to their specific care requirements. These creatures are known for their distinctive fan-shaped shells and their ability to "swim" by clapping their shells together, which propels them through the water. Scallops have a series of tiny blue eyes along the edge of their mantle, which help detect changes in light and movement, adding to their unique appearance.

In a reef aquarium, scallops require pristine water conditions and a well-established tank with stable parameters. They are filter feeders, relying on plankton and other microscopic organisms in the water column for nutrition. This means they need a mature tank with a healthy population of microfauna or supplemental feeding of phytoplankton. Scallops are sensitive to changes in water quality, so consistent monitoring and maintenance of water parameters are crucial for their survival.

Scallops can be a challenge to keep because they are prone to starvation in captivity if not provided with sufficient food. They also prefer moderate water flow to help carry food particles to them. When considering adding scallops to a marine tank, it is important to ensure that they are compatible with other tank inhabitants, as some fish and invertebrates might prey on them or outcompete them for food.

From a scientific perspective, scallops belong to the order Limida and are related to other bivalves like clams and oysters. Their unique locomotion and feeding strategies have been subjects of study in marine biology, providing insights into the adaptability and ecological roles of bivalves in marine ecosystems. For hobbyists, keeping scallops can be a rewarding experience if their specific needs are met, offering a glimpse into the complexity and beauty of marine life.
