"Henricia sanguinolenta," Wikipedia, the free encyclopedia. Henricia sanguinolenta is an invertebrate. It has slender five rays that taper evenly to tips that are connected by a central disc. The sea star grows to a diameter of 5 to 12 centimeters. On the oral side, the rays are smooth and have an ambulacral groove that contains two tube foot rows. On the dorsal side, the rays are rough with groupings of spinelets, each one have three to six glassy points. The sides of the rays are curving and smooth. The rays contain many of the organs in the sea star. On the tips of the rays are the eyespots. These are dark pigmented organs that sense the presence of light. The rays also contain parts of the pyloric stomach, parts of the nervous system, and most other organs.
