Vietnamese fishermen baffled by bizarre swirling sea creature

A group of fishermen from Vietnam were baffled recently by a bizarre creature they found in their net.

The men placed the unusual animal in the bottom half of a plastic bottle so they could observe it.

Footage filmed off the coast of Da Nang on May 2 showed the amorphous, brown animal swirling around in the bottle.

The fishermen said they thought it resembled a cross between an octopus, a jellyfish and a squid.

They released it shortly after the video was filmed.
