macroalgal and seagrass species  , while lower pH levels decrease calcification   or silicification  . Organisms' capacity to compensate for or resist acidification of internal fluids depends on their capacity for acid-base regulation, which differs due to organisms' wide-ranging biological complexity and adaptive abilities  . Detrimental impacts of acidification include decreased growth and survival, and altered development, especially in early life stages  , along with lowered recruitment and altered behaviour in animals . For finfish, laboratory studies of behavioural and sensory consequences of ocean acidification showed mixed results . Calcifiers are generally more sensitive to acidification  than non-calcifying groups  . For calcifying primary producers, including phytoplankton and coralline algae, ocean acidification has different, often opposing effects, for example, decreasing calcification while photosynthetic rates increase  .
