The guy with the Tubifex threw them in the glass water and said that is how they behave naturally. they naturally reside in the water.
So why are these sewer creatures suspended from a wall, for the most part above the water, if they're supposed to be Tubifex?
Also the contractions of the sewer creatures are much more unified, as one single organism, whereas the Tubifex just pass on a bit of movement to each
other.
Also, I didn't see the sort of membrane covering the sewer creatures in the Tubifex video.
Tubifex is found in poluted (river)water, rich with nutrients often next to sewage outlets. Part of the body is digged into the substrate (sand, mud
or slib) This is protection (they retract fast into the substrate when disturbed) and its holding them on the same (nutricious) spot.
If somehow a colonie of Tubifex ended up into a sewer pipe like in the video, they anchor themself on for example a tree root or another(artificial)
anchor point and each other. You can imagine a tiny single wurm
will flush away by current.
So now there is a colony above the waterline.
What will be different then underwater:
It will anchor very tight into each other to stay on the spot (as long there is a rich amound of nutrients flowing trough the colony)
The colony has to stay wet otherwise they will die very soon.
A slime and bacteria layer will form around the colony
Some animals will stretched to the sides for food, space or (?) attachment to the substrate.
The colony will have a high mortality rate cause being not in ideal circumstances. The dead specimens and not being in the right environment will give
the colony a slightly different pale colour and together with a bacteria film a membrane like appearance.
The ultimate proof/evidence would be a sample of the original sewer video, some of whats written above I cannot prove or have I seen myself.
