(B) Large Jrllerences in the survivorship of sponges from the two treatments were recorded. Although surviving caged sponges dell) were clearly visible, surviving sponges exposed to predation were visible only when the block they had attached to was broken open. Two halves ol .1 block trom an uncaged replicate (separated by a black plastic divider) are shown on the right. The inset slums the block before it was broken in half, and oscular openings can he seen on the surface (arrows). The spaces visible within the block on the nghl were created by horing activities ol forma vuriiin\. developmentally canali/.ed) trait. Second, in many ol the eaged replicates, it was impossible to place exclosures over the entire sponge: thus, portions of the sponge were exposed to predators. There may he enough integration within an individual sponge to communicate predation in one part of the body to other parts of the sponge. Finally, it is possible that not enough time had elapsed to allow phenotypic mod- ulation. If encrustation is a response to a stressful environ- ment (wave energy and predation intensity are both higher on the reef), then it is predicted that an organism will delay expression of a vulnerable trait, provided that it is plastic, long after the threat from a stress is gone (Palumbi. 1984;.
