A post mortem examination on a Fin whale that was found washed up on a beach in Norfolk revealed she died from starvation.
The 40ft whale was found dead on the shore between Burnham Overy and Holkham by wardens on Thursday.
An initial cordon around the whale was set up to allow scientists to carry out tests.
The Cetacean Strandings Investigation Programme say the whale developed a spinal abnormality which limited its amount of movement.
They say the whale had probably been dead for a few days, before it was found.
The Holkham estate and Natural England are now making arrangements to dispose of the carcass, which the public have been warned not to approach too closely.
