Seaweed locally

We think it quite extraordinary that we have Seaweed growing locally viz. beside the Thames. And of course, with the River being tidal, we can often smell the Sea!

A photograph taken during our Walk on Friday reminded us that a few years ago we had intended to see what different Seaweed' species we could find locally. Like lots of things, almost immediately forgotten! 

We initially thought the Seaweed in the picture below (lower right) keeping company with the Sea Milkwort &c. to be Bladder Wrack:

But we read that Bladder Wrack is often found with Egg Wrack (which can apparently live for decades) and which looks similar to Bladder Wrack although the fronds of Egg Wrack seem to be generally narrower that those of Bladder Wrack: both have distinctive air bladders and it seems that for Bladder Wrack, they are often in pairs. We wonder if both Wracks are present in the picture? As if we didn't have enough to worry about already!

Next time we are down by the Thames we shall take lots of Seaweed' pictures to see what we can find...
