The Dobhar-chú is a cryptid of Irish folklore, and the name roughly translates into “water hound”. It resembles both a dog and an otter although sometimes it’s described as a half dog and half fish. It lives in water and has fur with protective properties.
There have been many sightings documented throughout the years, one of the most recent ones was in 2003 when an Irish artist named Sean Corcoran and his wife claimed to have witnessed a Dobhar-chú on Omey Island in Connemara, County Galway. His description of the large creature is that it was large and black, made a haunting screech, could swim extremely fast, and had orange flippers like feet.
There is a headstone located in Conwall cemetery in Glenade that depicts a Dobhar-chú and is related to a tale of a woman being attacked by the creature. Legend has it that the woman (supposedly named Gráinne, was washing clothes and her husband heard her screaming for help, and when he arrived he saw his wife dead and the Dobhar-chú over her mutilated body. He killed the creature by stabbing it in the heart and when it died it let out a whistling noise, and nearby its mate rose up and went after the husband. After a long battle, he successfully killed that one as well. Of course, there is no definitive proof of this event taking place, but it’s still an interesting story nonetheless.
