Sea urchins

Eighteen marine species exposed to ocean acidification conditions for 60 days exhibited a wide range of responses. Ten of the 18 species were affected negatively with lower rates of net [...]

Sea urchins living in ocean acidification conditions for 45 days grew less. They were able to actively maintain the pH outside the cells in their bodies. (Laboratory study)

Sea urchin larvae from the Mediterranean Sea survived at higher rates under ocean acidification conditions, but they grew smaller. Warmer temperatures increased survival and growth rates of the [...]

Body fluids of the northern sea urchin became acidified when the urchins lived in ocean acidification conditions for 5 weeks. (Laboratory study)

Sea urchin larvae were able to maintain the pH inside their cells under ocean acidification conditions. (Laboratory study)

Sea urchin larvae normally have alkaline conditions (pH 9.5) in their stomachs. When larvae were exposed to ocean acidification conditions, the pH of their stomachs decreased. This change could [...]

Ocean and coastal acidification is occurring due to uptake of atmopsheric CO2, as well as nutrient-fueled respiration in some estuarine and costal environments. Multiple stressors, [...]

Anthropogenic CO2 emissions are acidifying the world’s oceans. A growing body of evidence demonstrates that ocean acidification can impact survival, growth, development and [...]

Ocean acidification (pH 7.7) impaired growth and development of an intertidal barnacle (Semibalanus balanoides), but warmer temperature (+4 °C) did not. The mineral composition of the [...]

Green sea urchins were able to adjust their internal pH level within 5 days after being placed in ocean acidification conditions, but sea stars (Leptasterias polaris) were not. Internal pH did [...]
