Cetaceans far from the sea (London and Cambridge)

       Cetaceans are admired by a large part of the society and we can see this even in the center of large cities far from the sea like London. Cetaceans are present in museums and art and even once a disoriented and ill northern bottlenose whale swam into central London, but that was a very strange event. Let's see....

June 2013: Sperm whale stranded in the Thames' riverbank in Greenwich, London!! 

Strange isn't it??   How could it be possible??

Cetaceans are one of the most impressive animals in museums due to their size.

A northern bottlenose whale Hyperoodon ampullatus in central London!!!!! and this is true!!!!

      In January 2006 a juvenile female of Northern bottlenose whale, Hyperoodon ampullatus, of 5 meters and weighed about 7 tonnes was spotted in The Thames River in central London. The whale appeared to have been lost, as her normal habitat would have been around the coasts of the far north of Scotland and Northern Ireland, and in the seas around the Artic Ocean. It was the first time the species had been seen in the Thames since records began in 1913. She died next day, and the postmortem examination revealed that she had died from a combination of problems including dehydration, muscle damage and kidney failure.
The reasons for the whale's presence in the Thames were unclear. A number of possible causes were raised prior to the post-mortem:
  • Illness. Some previous whale strandings are believed to have been caused by physical ill-health, resulting from factors such as parasite infections or pollution, which can disorientate whales and cause them to strand themselves in shallow water.
  • Noise pollution. There have been a number of incidents in which military sonar systems have caused hearing damage to marine mammals. It was suggested that Royal Navy sonar testing may have been a factor; however, the post-mortem revealed no damage to the whale's auditory functions.
  • A navigational error. According to the scientists who conducted the post-mortem, the most likely explanation for the incident was simply that the whale was seeking to return to its normal feeding grounds in the North Atlantic and took a wrong turn, mistakenly swimming west up the Thames rather than taking the longer route around the coast.

Meetings, conferences and environmental education activities related to the conservation of cetaceans and their environment are performed all over the world
I attended the Whale Fest in Brighton in October 2012 where I met people with different background (from researchers to whale watching companies and others) with a common interest in cetaceans and environmental conservation.
