River diving in Switzerland

Recommended Posts

Hi,

 

i spent a couple of days in Switzerland. I wanted to dive a mountain lake, but the road was still closed, so we end up in the river Maggia.

If anyone has an idea of the strange critter in the video (the same critter is at the end of the video with a fly!!!) please tell me.

I also posted in the Critter ID here on WP.

 

 

Watch what Maggia is like:

Hard to tell from your vid. See this:https://www.youtube.com/watch?v=hXfoFx-MY6s

If they are large they are more likely to be one of these. As suggested by this vid there is a lot of range in size. Many of the adults are quite large.

This last one has nice pix and a key but is US-centric.

 

Maybe finding something in German, French or Italian might get you closer

Thank you for the links! The critter looked more like the one from the youtube link, with the gills on the end.
