While the hairy shell certainly provides an admirable micro-habitat for many small encrusting and browsing animals, the extent of attachment by larger as well as smaller animals gives confirmatory information about the habits in situ of T. cancellata. To permit so much settlement and enable the attaching animals to grow so large, the snails must live fully exposed and move about very little. Aquarium observations are thus confirmed. 2 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
