Effects of seawater acidification on early development of the intertidal sea urchin Paracentrotus lividus (Lamarck 1816)

► Embryonic development of P. lividus is sensitive to ocean acidification. ► Offspring of P. lividus inhabiting tide pool may better resist ocean acidification. ► Possible acclimatization or adaptation of gametes of P. lividus to pH stress.
