Poor, poor River Cam. 1 of most disappointing swims we've had & our 1st in UK for 8 weeks. Should've been divine on this gorgeous summer evening, snorkelling 500m up from Braseley Bridge to Byron's Pool, water 17.4°C (air 23.8). But shockingly, visibility almost nil. #MySwim🧵1/5





Perhaps the awful visibility of the River Cam is why this fisherman is looking so thin & lethargic?
There's masses of fish in there, evident as they surface, but if they can't be seen otherwise, do the piscivorous birds go hungry?

#invertefest 🧵on amazing #marineinvertebrates of NW Sicily's Mediterranean. On night snorkel met incredible Spotted Bumble Bee Shrimp (Gnathophyllum elegans)! And Rugose Spider Crab (Herbstia condyliata)? but what's the zooming red shrimp that kept crashing into us? #MySwim 1/25 Other common crabs of the Gulf of Castellammare, Sicily include: Sea Urchin (Percon gibbesi) especially among break water boulders, Warty (Eriphia verrucosa), Runner Crab (Pachygrapsus marmoratus) - by anemone, & Mediterranean Intertidal Hermit (Clibanarius erythropus) crabs 2/25

After walking from #Freckenham down gorgeous Kennett-Lee Brook, a perfect-looking #chalkstream, as I slipped into #RiverLark at West Row on a perfect Saturday a.m., was buzzing with anticipation for a swim up Lee Brook. But, horrors! For almost a mile a DEAD ZONE!
#MySwim
1/7 Apart from some swarms of fish fry at the confluence of the Lee Brook with the #RiverLark, many of which were diseased, including these Roach, for the first mile, the only fish I saw were diseased or dead, such as this Perch & these Three-spined Sticklebacks.
