Newsfeeds High Carbon Dioxide Levels Cause Abnormally Large Fish Ear Bones ScienceDaily (June 26, 2009) — Rising carbon dioxide levels in the ocean have been shown to adversely affect shell-forming creatures and corals, and now a new study by researchers at Scripps Institution of Oceanography at UC San Diego has shown for the first time that CO2 can impact a fundamental bodily structure in fish. A brief paper published in the June 26 issue of the journal Science describes experiments in which fish that were exposed to high levels of carbon dioxide experienced abnormally large growth in their otoliths, or ear bones. Otoliths serve a vital function in fish by helping them sense orientation and acceleration. Go to complete article at ScienceDaily.com Articles TechnoOcean
