Adult sea urchins, Anthocidaris crassispina, were reared individually in running seawater equilibrated with gas mixtures containing 380 ppm (control), 1,000 ppm or 3,000 ppm CO2, at ambient natural temperature for 140 days to study effects of elevated CO2 on feed intake, fecal production, oxygen consumption, and the morphology of Aristotle’s lantern. Feed intake became significantly lower in the two high CO2 groups than in the control after 90 (1,000 ppm) or 110 (3,000 ppm) days and remained suppressed until the end of the experiment (control, 0.16 ± 0.01 (mean ± SE) g dry wt ind-1 day-1; 1,000 ppm, 0.10 ± …
