Many of the gorgonians are beautifully phosphorescent when brought to the surface, and their closely clustered branches, as in Calyptrophora (Fig. 459) are the abode of hosts of Crustacea, annelids, mollusks, and echinoderms, which find shelter there from their enemies. The Actinidse, or sea-anemones, so common in shallow water, are represented by a number of species in our deep waters; many of them are finely colored, some of them developing a peculiar base adapted to soft bottoms, representing perhaps, as has been suggested by Verrill, a primitive type from which the.
