Water Horses: more than just kelpies
Water horses as a mythological creatures appear in Celtic and Scandinavian folklore. They're shape-shifting water spirits, who lure and drag their unsuspecting victims to their demise. However, there are many types of water horses, differing from each other not only by places of origin but in behaviour. What they all have in common is: inhabiting bodies of water and taking the form of a horse.
I'll try my best to present the best known and least known ones, in simple to understand fashion. In advance, I want to apologies for any mistakes made. I'm only one person doing this partly as a story research and partly as my love/fascination for those creatures. I advise taking this post as a starting point and encourage to look into the folklore yourselves. Also, I apologies for any grammatical mistakes, English is my second language.
