Selenome
this huge, predatory sea creature was native to a single world, although its exact location was never discovered. Selenomes grew in huge reefs, a form of camouflage that allowed the colony to exist in plain sight. When a food source got too close to the reef, individual selenomes could reach out anf grab the prey. During the height of the Clone Wars, entire colonies of selenomes were exported by the Separatists for use as defense systems on aquatic worlds like Vandor-3.
