Just when you thought it was safe. Overfishing and human activities have led to jellyfish growth all over the world. And not just in population; this jellyfish, found off of the coast of Japan, is almost 5 feet across.

Not only that, but scientists have found jellyfish weighing up to 440 pounds.

Human runoff has created a nutrient-rich environment for these giant
jellies, and overfishing has reduced their competition in the oceans.
And now these giants are taking over, able to tear through fishing nets
and decimate local fishing populations.
