Even the tiniest animals in the sea are exposed to the global environmental challenge of marine litter. These little creatures are filter feeders, and indiscriminately feed on whatever is around. Microplastics in the oceans accumulate POPS, and these might then be accumulated up through the food chain when the plankton is eaten by larger animals.
The little green dots are pieces of plastic coloured with fluorescent dye so you can see them being ingested by the plankton - scary stuff!
