Increased acidity (-0.3-0.5 pH units) and hypercapnia significantly reduced larval calcification. A +3°C warming diminished the negative effects of acidification and hypercapnia on larval growth. WebSea cucumbers often lose body parts on purpose. They expel their innards, including their respiratory organs, digestive organs and gonads, as a means to distract an oncoming threat.
