At first, they did not know what it was.
“My son thought it was an alien or a monster,” said Pike, who is from Tulalip.
Luckily for him, his daughter had told him to carry his camera. He then took some pictures.
It wasn’t until he got home that he learned the 4-foot pile of goop was actually a lion’s mane jellyfish.
The jellyfish got stuck by the low tides, Pike said. He also made a video and uploaded it to YouTube.
This kind of jellyfish can grow up to 6 feet in diameter. Some have tentacles that can grow to nearly 30 yards long and can sting, even when the jellyfish is dead, according to the Pacific Wildlife Foundation website.
It is often found on Pacific Ocean beaches from Alaska to Mexico.
