Discussion: This species of boring sponge is found commonly on oyster beds in Long Island Sound, occurring from mean low water to depths of at least 10 meters. It is less common than C. celata and never, to my knowledge, overgrows its substratum completely to form free-living colonies as is true of celata. The morphology of Cliona vastifica has been described by Nasonov (1883, as Cliona stationis); Lendenfeld (1898); Topsent (1900); Vosmaer (1933); and Volz (1939). The spicules (fig. 5) are tylostyles which sometimes have subterminal or multiple heads; acanthoxeas, which are often more abundant than the tylostyles; and spirasters. The oxeas are usually spined but occasionally smooth or spined. Figure 5. Spicules of Cliona vastifica. A. Tylostyles. B. Smooth and microspined oxeas. C. Smooth and microspined spirasters.
