Seafloor teeming with life – as seen from end of the Dive sequence – with diverse sponges and algae of various shapes, sizes and colors. Tiny particles (white cloud) sink through the water towards the bottom.

Small shockwaves, possibly from an earthquake, rock the undersea environment. The arthropod Sidneyia is seen walking towards camera while several Marrella individuals swim through the water.

Camera starts ascent showing the benthic community from above. Mud flow moving fast in the distance and burying everything along its path.

A single large predatory arthropod, Anomalocaris,swims away from the approaching  mudflow, and rapidly passes camera, avoiding being engulfed by a split second.

Moments later, the mud flow reaches camera, covering the entire community, including the tallest Hazelia and Wapkia sponges.

End of sequence.
