The skeleton belongs to a juvenile male fin whale that died on 12 April 1955,[5][6] but is commonly mistaken as the remains of Hoi Wai,[5][6][7] a famous female orca that performed at Ocean Park Hong Kong from 1979 to 1997.
[5][6] The marine police originally intended to move the dead whale out to sea,[6] but were met by RV Alister Hardy, a research vessel of the University of Hong Kong (HKU).
The whale carcass was subsequently handed off to the research vessel, which towed it to Aberdeen on the south side of Hong Kong Island for processing by HKU zoologists.
Some superstitious fisherman worried that the "ghost fish" would bring bad luck, and in an attempt to pacify angry spirits, made an 8 m (26 ft) paper whale that they burned and released in Tseung Kwan O.
It intends on moving the original skeleton to its new biodiversity centre nearby for preservation, replacing the outdoor display with a 3D-printed copy that can withstand typhoons, salt spray, and Hong Kong's summer weather.
