Notes and Information

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.

Currently, as of this writing in December 2019, Oceanografic Valencia retains ownership of Petruska, though her loan to Pairi Daiza is long-term and 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 is being 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.
