And then there’s the grizzly bear, ursus arctos horribilis, horrible bear bear. My favourite part is that ‘horribilis’ is a mistranslation from English into Latin; ‘grisly’ is synonymous with ‘horrible’, but ‘grizzly’ actually means ‘greyish’

Edit: Ursus arctos griseus or Ursus arctos canescens would be the most likely names of it had been translated correctly (grey bear bear and greying (with age) bear bear, respectively)
