Ocean Acidification Leads to Broadening of Crab Predators and Faster Predation Rate on Mussels
Ocean acidification is caused by the dissolved carbon dioxide in the oceans lowering the amount of free carbonate ions. This is turn, affects the ability of calcifying organisms like mussels to build thick shells to protect against predation. Mussels are often preyed upon by both specialist crabs, l...

Crab preference to regular or thinned mussels was recorded during feeding trials. Times were taken for the time it took crabs to break the shells of both regular and thinned mussels. Kelp crab only ate the thinned mussels, meaning they could become a more frequent predator for mussels during ocean acidification conditions. Red Rock crab also preferred thinned mussels and it took them less time to break into them. The differences in feeding preference and breaking time for thinned and regular mussels were significant.
