Swim into this eerie tale! Breton sailors in 1600s Brittany swore a sea hag sank nets. The crew claimed she shimmered, then dove. Sailor tales, noted in 1610 French records, describe a 5-foot figure, linked to net destruction (crime), vanishing into water (interdimensional, adapted). Groac'h is a rare Breton cryptid, reported as a sea hag in early 17th-century accounts.
