Pollution threat to Irish killer whales

A pod of killer whales which regularly swims in Irish waters is feared to be in danger of dying out due to pollution.

The killer whales — who have been given nicknames such as John Coe, Floppy Fin, and Nicola — are believed to be the only resident population of orcas around Ireland and Britain.

However, while they are the only known residents, marine biologist Simon Berrow of the Irish Whale and Dolphin Group revealed that Irish waters are a regular playground for passing families of orcas.
