Stories from Oatake · Japan

Thousands of lion's mane jellyfish, identified as Cyanea rosea, were observed on a beach at the high tide mark. An older resident of Oatake reported seeing a quantity of the jellyfish approximately one week ago. The observer stated they had never seen such a large number of these specific jellyfish before. Earth Sciences officials stated that while spring and summer wash-ups are not unusual, winter occurrences are less common. These jellyfish are considered dangerous and can deliver a nasty sting to humans or pets upon contact. Authorities advise people to keep away from the organisms. Observed specimens on the beach were approximately the size of a dinner plate, though they can reach two meters in diameter in the water.
