Well, this sure was an interesting round. To begin with, I had started out thinking I would use the word "ophiuran." Then I found another source for the definition of what I thought was for "ophiuran," but when I was tabulating the results and double-checked the link, I realized that the definition I used was for "ophiura." It appears they are about the same, but...well, it is what it is.
Then Mike suggested that I should have combined his definition with mine, which probably would have resulted in fewer votes for the "real" definition due to the "star" similarity that attracted many voters. Since I didn't do so, Mike is our next dealer with 6 points. Here are the (correct, I hope!) results in table form as a .jpg and also attached as a .pdf file.
