Selma

The Selma is a gigantic serpent native to the icy lakes of Norway. Unlike the peaceful sea serpent, the Selma is a ferocious creature, consisting on a diet of fish and human flesh.

Rather than their usual group of preforming trolls, the Norwegian National Quidditch team elected to bring a Selma as their mascot for the 2014 Quidditch World Cup, a decision defended by team manager Arnulf Moe as reflecting the "steely determination and ferocity" of his team. The Selma was placed in a magical lake in the Patagonian Desert where it engaged in a fight with the Fijian Dukuwaqa, which eventually escalated into a conflict between many of the team mascots.

Behind the scenes

 * The Selma is a cryptid said to live in the Norwegian lake, and could be considered Norway's Loch Ness Monster.
 * Newt Scamander did not mention Selmas in his sea serpent entry in Fantastic Beasts and Where To Find Them. It is possible that the species had not yet been discovered by 1991.
