Chitons are generally herbivorous grazers, though some are omnivorous and some carnivorous. [34] [35] They eat algae, bryozoans, diatoms, barnacles, and sometimes bacteria by scraping the rocky substrate with their well-developed radulae. A few species of chitons are predatory, such as the small western Pacific species Placiphorella velata ...
These chitons can be found in intertidal zones to 40m depths. Heavy waves on rocky shores are favorable. K. tunicata is unique compared to other chitons in that it tolerates direct sunlight. These intertidal zones are susceptible to contamination from industrial activities, timber harvesting, mining, seafood processing, as well as coastal ...
Mopalia muscosa, the mossy chiton, is a species of chiton, a polyplacophoran, an eight-plated marine mollusk. It is a northeastern Pacific species which occurs from British Columbia, Canada, to Baja California Mexico. [1] [2] [3] This species is found in the middle and lower intertidal zone on exposed rocky shores.
A toxic algae bloom is injuring or killing scores of marine animals, from fish to sea lions and dolphins. Along the Southern California coast, there are deadly signs of a warming ocean. ...

Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green.
The San Pedro-based Marine Mammal Care Center is in need of donations and volunteers as it combats an algae bloom that has killed or sickened more than 1,000 creatures.
Hermit crabs and live Tegula snails on a dead gumboot chiton, Cryptochiton stelleri, in a tide pool at low tide in central California. Although intertidal ecology has traditionally focused on these negative interactions (predation and competition), there is emerging evidence that positive interactions are also important. [17]
