Whale post-mortem results revealed

The results of a post-mortem on the Thames whale has revealed that it died of multiple causes.

The post-mortem found that the whale, a young female northern bottlenose, died from severe hydration, muscle damage and kidney failure.

It is believed that the 19ft animal had probably mistakenly swum into the North Sea and had ended up in the Thames while trying to return to its feeding grounds in the Atlantic Ocean.

The findings suggested that the whale had not been able to feed on its normal diet of deep-water squid for three days.

Dr Paul Jepson, a veterinary pathologist, said: "Whales and dolphins obtain water from their food and northern bottlenose whales normally feed on deep water squid in the Atlantic Ocean.

"This animal would not have been able to feed while in the North Sea and so would have become dehydrated."

Scientists examined the whale's body for almost eight hours at the dockside in Denton, Kent, before samples were taken to the Zoological Society of London for further analysis.

Further tests will be carried out to discover if there were any infections or pollutants in the whale's body, such as heavy metals.

However, Dr Jepson ruled out the possibility that sonar from Royal Navy ships could have disorientated the whale and led to it ending up in the Thames.

The whale made headlines around the world last Friday, when it first appeared in the Thames - the first time such a creature had been spotted in the river since records began in 1913.

However, it became disorientated and distressed and attempted to beach itself several times, before a rescue operation was launched. However, the whale died on board a rescue barge, as it was being transported to deeper waters.

Dr Jepson said that the decision had been made to put the animal down, when she became even more distressed, but he said: "While I was drawing the lethal injection, she died."

Dr Jepson said: "The last few days have been an unforgettable and ultimately sad experience for us all and we are now determined that the whale did not die in vain.

"The incident has demonstrated a clear message of the nation's passion for these animals and their conservation."

The whale's bones will be kept at the National History Museum for scientific research.
