A wolf in sheep's clothing: carnivory in dominant sea urchins in the Mediterranean
Marine Ecology Progress Series
Arbacia lixula and Paracentrotus lividus are the dominant sea urchins in the Mediterranean sublittoral, where they are key structuring species due to their grazing activity. It has been commonly accepted that competition between both species is minimized by specializing in different algal foods. A. lixula is considered to feed mainly on encrusting coralline algae, while P. lividus prefers fleshy macroalgae. We used stable isotope analysis to test if these species occupy different trophicdoi:10.3354/meps09359 fatcat:xfva5qzdr5fjzcfxkfbrkm3p5y
