One Whale was founded to track the beluga, which rose to fame after being spotted in Norwegian waters five years ago.

A beluga whale suspected of having been trained as a spy by Russia has been found dead off the Norwegian coast.

Menopause is known to exist in five species of toothed whale: short-finned pilot whales, false killer whales, killer whales, narwhals and beluga whales.
