Mega isopod attacking a shark

[Magical Realist]

Bear in mind that when biologists talk about a giant isopod, they are talking about one that is only about 20 inches long. Now take a look at what is attacking the shark in this video.
I am never going swimming in the ocean ever again..

Just from the glimpse of it that we see, it looks like an Isopod.

But way bigger than any I've ever heard of.

And the big (20 inch) isopods that I've heard of are scavengers that eat prey that's already dead and falls to the ocean floor. Huge ones that eat living prey and can kill a shark would seem to be new to science.

Pretty awful too, I will say. Scary things.

There might be all kinds of as-yet unknown animal species in the depths of the oceans. (Cryptozoology)

Since there's no reference for scale, those sharks could be relatively small.
It could be a octopus with the membrane between it's tentacles flared out, or a 16" isopod, which is plenty big for a small shark.
