The Butterfly Snail (Limacina helicina) is a species of predatory swimming marine snail. They are a keystone species within Arctic pelagic ecosystems and are currently under serious threat.
They are being impacted by Ocean Acidification, due to pollution the ocean waters are becoming too acidic for survival. The corrosive waters off the West Coast of the U.S are dissolving the shells of these unique creatures and inevitably killing them. The decline of these will have major flow on effects to major marine ecosystems.
