locomotion Dissection Steps 1. Begin cutting down the central part of ray 1. Identify Digestive Glands 2. Identify connection of digestive glands to the

pyloric stomach 2. Investigate stomach 1. Find Pyloric and Cardiac Stomachs 2. Find where Pyloric Stomach connects to digestive glands and anus

3. Find stone canal and Madroporite 1. Examine Tube Feet, Gonads, Radial & Ring Cannals, Ampullae Begin to cut down
