After analysing the picture, experts agreed Pi was female. Pi got her name for a scar near the dorsal fin which is in the shape of the mathematical symbol Pi, according to Isles of Scilly Wildlife Trust.

Free-diving instructor Emily Marzilli and her friends had a close encounter with a Bryde's whale while observing a large school of sardines in Magdalena Bay off Baja California Sur

Having a fiance, Stuart Bearhop, who worked as a professor of ecology at the University of Exeter proved useful, as he asked around and found out about a semi-secretive mission to save the whale's head from incineration. The man who carried out the mission was scientist Prof Robbie McDonald.

A deadly pathogen known as cetacean morbillivirus has been detected in Arctic waters for the first time. Researchers found it using a new technique to monitor the whales’ health: flying a drone over the creatures to catch their breath.
