  • Fragile butterflies of the sea

    Scientists at the Monterey Bay Aquarium Research Institute (MBARI) have been studying and documenting the lives of pteropods, swimming snails of the sea that play a critical role in ocean food webs. They’re delicate and beautiful animals, sometimes called “sea butterflies”, with interesting ways of finding food in the deep ocean. They’re also particularly vulnerable to ocean acidification, the change in chemistry that occurs as the ocean absorbs more of the rampant carbon dioxide produced when we burn fossil fuels.
