John Coe (an old and very well known killer whale) and Aquarius, have been sighted off the coast of Cornwall.
A rare sighting in the south of the UK, this British pod of Orca is heavily endangered. With no calves sighted since 1990 the sightings are only likely to get rarer still.
One of the main causes, is human pollution, due to chemicals such as PCB that wash into the seas of the UK. These can lead to poor health and infertility in the animals in our waters.
