I also once saw a lamprey climbing up the slope in the nearside shallows, I say climbing rather than swimming as it was using its sucker like a tool to inch its way up the slope against the strong current like a mountaineer would use an axe to make footholds up a mountain (well possibly not but you get my drift).
Anyhow it was fascinating to watch but unfortunately it was one of those days when I didn't have my camera, unlike the following occasion when I had my one and only encounter (to date) with a signal crayfish.
The water level was quite low this day (in October 2010) when I leaned over the fence and spotted what I at first thought was an escaped(?) lobster (honest it was massive) but of course it soon clicked that a lobster wouldn't survive in fresh water (ask Jimmy Somerville of Communards fame, d'oh!) and it must be a crayfish, though I really didn't expect to see one this size.
Anyway it entertained me for some time and I caught the whole event on camera, so here are the brief photographic highlights. :
|I first spotted it in the shallows in shadow of the wall|
below the fence
|It must've taken offence at me taking photos as it started gesticulating|
in my direction with its claws at the base of the wall . . .
|. . . and started to climb out of the water towards me|
up the sheer vertical wall !?!
|Luckily for me its anger only got it so far up then it|
fell backwards into the weir . . .
|. . .where it picked itself up, dusted itself down, but had more |
sense than to start all over again.
|And after taking a few steps it stopped and snacked on a dead leaf, |
where it remained up 'til the point I had to leave.
So there it was, an interesting little scene, and for all the nastiness associated with this invasive predatory species it was still a memorable sighting, though as a dragonhunter I sometimes wonder what effect they have on numbers of banded demoiselle larvae in the river (though not much judging by the numbers seen last summer :)
So all that remains to ask is, was it Ronnie or Reggie?
