A humpback whale known as Timmy lived for five days after being released back into the North Sea by rescuers. Data from a tracking device attached to the whale confirmed it returned to the Baltic Sea, traveling 215 kilometers (133 miles). The information comes from Till Backhaus, the Minister of the Environment for Mecklenburg-Vorpommern, who announced the findings on Friday. The tracking device was recovered from the whale’s carcass after its death. This data provides insight into the whale’s movements following its rescue and subsequent release. The cause of Timmy’s death remains undetermined at this time.
