After invading the nuclear plants in Japan and Scotland, this breed of free-swimmers are now heading towards Kayak Point, Washington.

A startling 4-foot jellyfish, believed to be the Lion's Mane, has washed ashore the park after being probably stuck by low tides.

The largest known species of jellyfish, the Lion's Mane has the capacity of a bell diameter of 8.2 feet with tentacles trailing as long as 98 feet or even more.

The largest recorded specimen was found in the year 1870 in Massachusetts Bay having a bell diameter of 7 feet 6 inches and tentacles 120 feet long.

The Kayak Point species was discovered by Sherman Pike and his son, Oliver who initially thought it to be some kind of an alien.
