Polar bear at Calgary Zoo died by drowning following 'crushing' injury

The Wilder Institute/Calgary Zoo has revealed the cause of death for polar bear Baffin last week. The zoo said seven-year-old Baffin had been sparring with eight-year-old polar bear Siku in the pool in their enclosure on Friday, but went under the water and failed to resurface. On Monday, following a necropsy, the zoo announced Baffin died by drowning following a "crushing injury to his trachea" by Siku during the "rough play."
