Clams – Beautiful and Talented

Squamosa Clam 225x300 Clams – Beautiful and Talented Giant clams (Hippopus and Tridacna species) are already known to play a part in various important ecological roles in coral reef ecosystems, but so far, many of these roles are poorly understood. Now, a team of marine ecologists from the National University of Singapore have show how clams have been doing a lot more than perhaps they have so far been given credit for. For a start, clam shells both contribute to the structure of the reef (some species produce 80 tonnes of carbonate shell material per hectare each year) and they provide a substrate for colonisation by a host of other organisms. On the inside, the fleshy mantle cavity can host a myriad of commensal and ectoparasitic organisms while clam tissues are food for a wide array of predators and scavengers. Discharges of live zooxanthellae, waste products and spawnings are also eaten by opportunistic feeders and they can even potentially counteract eutrophication via water filtering More: Clams – Beautiful and Talented
