 The Mediterranean Sea is heavily polluted by marine litter, including microplastics, which can be harmful to large filter-feeding animals like the fin whale. Researchers have found that the fin whale's feeding grounds are often located near areas where there is a high concentration of microplastics. This suggests that the fin whale may be exposed to these potentially dangerous particles while they are feeding.
