Images: 

I took this picture in St. Lucia. The water depth was between 25 and 60 feet. The size was several feet across and I've been searching my book for an identification image. The closest thing I can find is a basket star when it is closed but this was much larger than what my book describes. Notice the arms of the feather star in the forground as they were 7-10 inches long. Can anyone steer me in the right direction? Thanks in advance
