The Warner expedition of 2009 discovered a monstrous serpent like that of the lugworm, that gets its nutrition from the dust and the microorganisms that reside in the sediment. Loch Ness and Iceland hold smaller examples of these Amazonian giants.
These creatures can be found in freshwater and saltwater.
See Mike’s blog, various videos.
The following images show the movement of one of these giants from a few miles below the settlement of Indiana. It located itself close to a wormhole that flows under the village and exits at Mazan on the Napo river.
Note the discolouring of the water when the sediment is disturbed.
