Nature is indeed wild. This video was captured by Twitter user Chamberea on the coast of Northern California.

The footage was taken of an octopus which had trapped a fish in a tide pool. After luring the fish in, the octopus strikes. The fish flails and flops in desperation, but to no avail. The octopus is stronger.

In the second video below, the fish can be seen swimming from underneath the octopus' skin. An eerie and chilling sight for sure. But that's nature, baby.
