Two Deep-water Pennatulids, showing the long stalks, with bases embedded 

 in the ooze, which lift the polyps up into the water. The colony to the 

 right, Chunella, has the polyps in distant whorls; the other, a commoner 

 type, Funiculina, has the polyps crowded together on the upper part of 

 the axis, which may be over a yard in length. Both forms illustrate a 

 simple adaptation to life on the floor of the sea at considerable depths.
