Notes and Information
Petruska died giving birth to her first calf, which was positioned improperly in utero and unable to be delivered. She and her calf have been donated to the Ghent University Museum where their skeletons will be placed on public display.
Oceanografic's initial herd of five walruses, including this individual, were all estimated to be 6 months old upon arrival to the park. I assume the walruses arrived in early December; sources say they arrived a month prior to December 27th, and on the week of December 12th.
Oceanografic Valencia retained ownership of Petruska as she was sent on long-term loan to Pairi Daiza, which was expected to last no less than ten years at least.
This walrus's name was originally spelled "Petrushka" for the first 16 years of her life before being altered to "Petruska" upon her transfer to Tierpark Hagenbeck in 2019, the use of which was continued at Pairi Daiza. Her name has also been spelled "Petrouschka" by Pairi Daiza, and "Petroesjka" by the Dutch media.
Petruska was transferred to Hagenbeck on breeding loan on or prior to January 26th, 2021.
