Genus
Common name: Thorny oysters
Scientific name: Spondylus
Spondylus, commonly known as thorny oysters, are bivalve mollusks recognized for their colorful and spiny shells. They are sessile and often found attached to hard substrates in the reef environment. Thorny oysters are filter feeders, sieving plankton from the water column. They are not commonly kept in home aquariums due to their specialized needs, but can be a unique addition for advanced hobbyists. Their care involves stable water conditions and moderate to strong water flow to mimic their natural habitat.
