Tridacna crocea are beautiful clams oftentimes displaying a variety of colorations with intricate patterns. These clams are also referred to as Crocea Clam, Boring Clam or Crocus Clam, and are the smallest of all Tridacna spp.,reaching a maximum size of 6" in the wild. The Crocea Clam can penetrate through limestone substrates by releasing an acid to break down the carbonate in the stone. It uses the ridges of its thick shell to dig into the rock by opening and closing quickly through the use of its large byssal muscle, giving the clam the common name "boring clam." This burrowing behavior helps to protect it from predators such as sea stars, along with Angelfishes, Butterflyfishes, and other reef dwelling species that consume bivalves.
