# Molgula

Molgula, or sea grapes, are very common, globular, individual marine tunicates roughly the size of grapes.
They are translucent with two protruding siphons. They are found subtidally, attached to slow-moving submerged objects or organisms. All species of Molgula have a fluid-filled structure called the renal sac. The renal sac contains nitrogenous wastes, solid concretions composed of weddellite and calcite, and an apicomplexan symbiont called Nephromyces.
In the western Atlantic Ocean, they range from the Arctic to North Carolina, to the center of the United States Eastern Seaboard.
