In some long-term studies of Mytilus californianus it was observed that gaps could continue to increase in size post-disturbance due to wave action and predation (Paine & Levin, 1981; Brosnan & Crumrine, 1994; Smith & Murray, 2005) potentially due to the weakening of the byssus threads leaving them more vulnerable to environmental conditions (Denny 1987). crab. They are the main source of food for both the Ochre Sea Star (Pisaster Ochracus) and the rock whelk (Nucella emarginata).
