Ocean Park is investigating what the accidental death of a year-old male spotted seal.
The seal died during an incident at about 2.30pm on Monday (1/6/2015) during a backwash cycle on filters at the Polar Adventure attraction which opened in 2012 and features different species of penguins, walruses, seals and sealions. In subtropical Hong Kong the energy-intensive attraction is kept at 8-10 degrees C for species native to the South Pole, with 15 to 17 degrees C for North Pole species.
The accident appeared to be the result of the animal becoming trapped against an outlet during the backwash operation, but the exact cause of death had not been confirmed after an examination of the body was carried out on Monday.
The dead seal had been born in captivity at the park.
Animal deaths are quite a frequent occurrence at Ocean Park. In 2014, 59 fish died at the Ocean Aquarium due to human error. Also in 2014, 2 rare Chinese sturgeons died from viral infections.
