Pontoons were used to try and free the whale from mudflats
It will be several weeks before the results of a post-mortem examination will be known on a 26ft (8m) whale that beached on a mudflat in Hampshire.
The Northern Bottlenose was killed with a lethal injection on Friday after it became trapped in Langstone Harbour.
Blood tests showed the whale had renal failure and had no chance of survival even if it made it into the Solent.
Samples were taken on Saturday and will be sent to laboratories around the country for analysis.
The body will then be disposed of either out at sea or in a landfill site.
An operation to try to save the whale, believed to be a young adult, began on Thursday.
About a dozen firefighters, police, coastguards, the Ryde Inshore Rescue Independent Lifeboat and Hayling Island harbour staff took part in the rescue attempt.
It was the same species of whale as one that died despite a massive rescue attempt to save it when it swam up the River Thames in January 2006.
