Common name: Spondylidae

The Spondylidae family, commonly known as thorny oysters, comprises bivalve mollusks recognizable for their colorful and often spiny shells. These sessile invertebrates are filter feeders, playing a role in water purification. In reef aquariums, they can add a touch of exotic appeal with their unique appearance. They require stable water conditions and benefit from moderate water flow and lighting. Thorny oysters often host a variety of symbiotic organisms, including small crabs and shrimps, which can add to the biodiversity of a reef tank.
