Can transform from a shark into a man
The Dukuwaqa was a magical creature native to the warm oceans around Fiji. A shape-shifter, the Dukuwaqa possesses the ability to transform itself from a man into a shark and back (something impossible for non-Animagus wizards, as transformation into an animal renders the transformed individual with the mind of that animal, and are thus unable to perform the spell needed to transform back into a human). A Dukuwaqa was the mascot of the Fijian National Quidditch team.
For the opening ceremony of the 2014 Quidditch World Cup, the Fijian team transported their Dukuwaqa to a magical lake created by the Argentinian Council of Magic in the Patagonian Desert. During the ceremony, the Dukuwaqa, upset by being relocated from the warm open ocean to a small tepid lake, attacked the Norwegian's Selma it was meant to share the lake with. Attempts by both nations to stop the fighting were hampered by the Brazilian Curupiras, who believed the handlers to be attempting to cause the creatures harm.
Behind the scenes
- The Dakuwaqa is a god from Fijian mythology, a protector spirit to fisherman. Though he is reputed to be capable of taking on any shape, his preferred form is a Fijian male with the head of a shark.
- Newt Scamander did not cover the Dukuwaqa in Fantastic Beasts and Where To Find Them. It is possible that they are classified as Beings or that the species had not been discovered in 1991.
