“The thing that truly surprised me the most was that every salp, regardless of year collected, species, life stage, or part of the ocean collected, had plastic in its stomach,” says biological oceanographer Jennifer Brandon.
Salps are small transparent sea creatures that feed constantly on nanophyto- or microzooplankton while swimming in all of the worlds seas and oceans. The microplastics they ingest are as small as 10 micrometers, smaller than the width of a human hair. The 100% ingestion rate is alarming since salp digest their food in two to seven hours.
Brandon warns, mini-microplastics in the salp could make their way into the human body through the seafood we enjoy that eat salp. More than one-third of mini-microplastics found were synthetic fabric fibers from polyester or nylon. Car tires were the second-leading source, which release plastic particles as they erode.
