Star Fish Dissection

My starfish specimen was very stiff and spiny to the touch. It had 5 radial arms, and the whole starfish was larger than I thought and had a peachy. brown colour.

  On the bottom of the starfish there are the tube feet that are used for locomotion. I was lucky to have a specimen that had an everted stomach, which spurts out gastric juices to digest its food before it engulfs it.

The starfish seemed to be only filled with brown goo, I was surprised by this as I thought it would a bit more complex. After this dissection I am curious as to how the starfish digests its prey and I would not mind seeing a video of it.
