Humpback Whale “Timmy” Likely Lived Until May 7 After Release

The humpback whale nicknamed “Timmy” was rescued off the German Baltic coast, fitted with a satellite tag and released on 2 May in the Skagerrak, about 70 km north of Skagen, Denmark. Data from the tag, now fully analysed, show the animal travelled roughly 215 km after release, with depth and temperature records indicating it was still active until around 6 – 7 May.

The whale was found dead on 14 May near the Danish island of Anholt; the exact cause of death remains unclear. The tag did not transmit location data because it was not properly tested before deployment, and it recorded only movement and environmental parameters, not heart‑rate or breathing. Experts have criticised the handling of the tag and the rescue operation. Mecklenburg‑Vorpommern’s environment minister Till Backhaus will present the findings, and the carcass is slated for conversion into biodiesel in Denmark.

The incident has sparked debate over the rescue’s effectiveness and the welfare of large marine mammals in such interventions.
