Diagram of Starfish Features There are a total of eight species found in the genusAsterias. They have five arms that are broad at the base and taper at the end and curl up a little too. The tube feet present on the lower surfaces of their arms are tubular projections that are a part ...
each connected to a central body disk that contains themouthand integratednervous system. Each of the arms has its own gonad (in the adult), nerve system, and digestive organ connected to the central digestive system. The mouth is on the bottom (ventral, oral surface) surface of the animal...

Contained within the arms and attached to the internal surface of the body wall are the gonads and components of the digestive system—the pyloric caeca and the extrinsic elements of the stomach retractor apparatus (Figure 2 and Figure 3A). Figure 2. Diagram of a transverse section of an arm...
