Researchers said a tornadolike formation caught on camera off the coast of Australia was "completely weird."

Schmidt Ocean Institute researchers were performing live commentary on a live-stream video of a remotely operated vehicle dive in Coral Sea Marine Park, off the Queensland coast, when the underwater tornado appeared on the sea floor.

The commentators described the formation as "amazing," "completely weird" and "really unusual."

Marine geologist Robin Beaman, one of the scientists performing the commentary, said the formation was reminiscent of a benthic storm, which involves waves traveling under the surface and creating turbulence near the ocean floor.

The scientists said they do not know the cause of the whirling water.
