9. Dobharchú
The Dobharchú, or “water hound,” is a formidable creature in Irish folklore, resembling a giant otter with a dog-like head. Known for its aggression, it is said to inhabit lakes and rivers, preying on both animals and humans. Sightings have been reported in areas like County Leitrim, where a headstone depicts the creature, commemorating an alleged attack. Its legend parallels that of Scotland’s Loch Ness Monster, reflecting regional intrigue (irishcentral.com).
