<div><p>Data describe the percent algal substrate grazed by sea urchins in trophic cascade experiment. Treatments included full predator exclusion with 4 urchins and predator access (fence with 4 urchins) for two species of urchin (<em>Eucidaris galapagensis</em> and <em>Lytechinus semituberculatus</em>) conducted on 23 June – 1 July 2012 and 13 – 20 July 2012, respectively. Experimental concrete bases were photographed and digitized for percent cover of grazed substrate. Experiments were conducted at 10 m depth at Baltra Island, Galápagos Islands.</p>
<p>See Witman, J.D., et al (2015) for description of the experimental design.</p></div>
