Salps are a colonial, barrel-shaped group of species that pump water through their transparent bodies, filtering out even the smallest phytoplankton. Aaron Sanders

Satellite images show how Antarctica’s vanishing sea ice is changing the food chain

With the loss of sea ice, tiny filter feeders known as ‘salps’ can thrive, while shrimp-like krill lose out.

Antarctic krill store as much carbon as the world’s mangroves, salt marshes and seagrass beds

For the first time, we used a computer model of ocean currents to show that krill waste products don’t need to reach great depths to achieve carbon storage for at least 100 years.
