Whale sharks eat thousands of plastic pieces a day

The biggest fish feeds by filtering water for plankton

Whale sharks could be swallowing 137 pieces of plastic an hour because the surface waters where they feed are so contaminated, a study has found.

The biggest fish, which can reach 12m (40ft) long and weigh 40 tonnes, ingest hundreds of cubic metres of water a day and filter it to extract tiny plankton.
