Content overview: “Rare Two-Headed Turtle Hatchling Found on Cape Cod—Third in Five Years”. A rare two-headed diamondback terrapin hatchling has been discovered on Cape Cod, marking the third such bicephalic turtle found in the area over the past five years. The unusual find was made by a local wildlife organization, though the exact location and circumstances of the discovery were not detailed in the source. The hatchling is a diamondback terrapin, a species native to the brackish coastal marshes of the eastern United States, and its condition—known as bicephaly—is an extremely rare congenital anomaly that occurs when an embryo begins to split into twins but fails to complete the process.
Such animals often face significant challenges in the wild, including difficulties with movement, feeding, and avoiding predators, and their survival rate is generally low. The discovery adds to a small but notable cluster of bicephalic terrapins reported on Cape Cod in recent years, with previous cases documented in 2020 and 2022.
