Sperm whale, Thames estuary, February 2019
A beleaguered sperm whale died three days after it swam up the Thames estuary and was unable to escape.
The desperate animal also ended up stranded at times, as the level of the tidal river shifted, before it was pronounced dead by rescuers on February 1 this year.
The whale, which is usually found in deep water, had appeared confused and had been regularly changing direction as it swam off the Swale in north Kent.
Its body was taken for examination by the Cetacean Stranding Investigation Program so they could try to establish why the ocean going animal had come into the Thames.

Sperm Whale, Scotland, December 2019
A sperm whale died after it washed up in Scotland with a 220lb ball of fishing nets, plastic cups, plastic bags and other litter inside its stomach.
The 45-foot-long leviathan's corpse, which was found on Seilebost beach on the Isle of Harris, Outer Hebridies, also contained rope, gloves, packing straps and tubing.
'All this material was in a huge ball in the stomach and some of it looked like it had been there for some time,' a spokesman from rescue group Scottish Marine Animals Stranding Scheme said.
However, it is thought the cause of death was the animal becoming disorientated during storms before becoming stranded. Sperm whales dive to great depths to eat squid and are known to accidentally eat plastic after mistaking it for their prey of choice.
