FLOATING IN HISTORY

I went to a fish and chip restaurant earlier today. There was a huge globe with two fish swimming round in it.

“That’s cruel,” I said to a friend who was munching his chips alongside me.

He thought I meant it was cruel to keep fish in a bowl. We were looking at it through a frosted glass screen. Every so often, a fish shape would emerge from the whiteness, float by and disappear again as it turned the corner and swam away.

“Those fish may be smaller than they seem,” he suggested. “Maybe the glass is magnifying them.”

But I wasn’t talking about the relative size of fish to bowl. What seemed cruel to me was that live fish were being kept right beside the place where battered ones were being fried.

He was logical.

“It’s no different,” he said, “from us seeing lamb stew. Those fish won’t identify with cod any more than most of us identify with mammals other than humans while they are being cooked.”

I floundered around by saying I wouldn’t like to be in the same room as a chimpanzee being roasted but he was right. I was guilty of an ‘ism’. All fish, to me, are fish. Just fish. I know they have different names and different attributes but I’ve tended to think of these differences in about the same way as I see differences in skin shade or hair colour. Humans are humans. Fish are fish. But it isn’t like that.

Psathyrella
Meandering on in my thoughts, I began to wonder why humans don’t feature in a nature blog. We are as much part of nature as a leaf is. And the men who were strimming over the patch where I had been observing these toadstools are as much part of nature as are fungi. They are practical humans too for they are preparing a place where lorries and equipment can go while a bridge is being mended nearby. I wouldn’t want the bridge to fall on me for the sake of leaving the undergrowth undisturbed. None the less, I was disappointed not to have watched the toadstools right through from their fairy tale beginnings to their tatty end.

It’s an odd thing, watching the same spot each autumn to see whether particular fungi return.

Probably a Phellinus
I’ve been watching this one for three years (20082009) and I think it may be the last time I take its picture for the log it lives on is sinking into the muddy little stream it rests in and the fungus itself seems, somehow, less enthusiastic about life than it used to.

Fungi and lichen are peculiar enough as life-forms - and I haven’t managed to grasp why, when red seaweeds are algae, green seaweeds aren’t. They look much the same. But brown seaweeds aren’t even plants. They seem to be something all on their own! And I’ve been looking at diagrams about how Bladder Wrack reproduces (a brown seaweed which looks green to me when I see it lying around on the beach) - and there are sperms and eggs! What! I thought sperms and eggs were reserved for . . . I’m losing my way . . . for . . . for non-plants! Oh. But they aren’t plants. But they look  like plants!

Sea Squirt
(probably Ascidiella aspersa)
 
Sea Squirt

I’ve also been disconcerted to discover that this (a dying and therefore miss-shapen sea squirt) is our closest living invertebrate relative. It belongs in the same phylum as we do - in other words, they are part of our family tree. If Victorians struggling for the first time with the concept of evolution got all uptight because we are related to monkeys (not descended, note, that’s different) how fortunate it is that sea-squirts have not figured highly in the public consciousness. Their digestive system seems to be a kind of U bend with what comes out coming out right next to where it went in. They also absorb their own brains. I really am not understanding anything. The world becomes less comprehensible every time I look at it!

(According to this article sea-squirts may give us a good idea of what our early human ancestors looked like. Brilliant!)

Here’s an oyster thief. It got its name because if it attaches itself to oysters instead of to rocks, being hollow inside, it floats away with them. It is an alga. Whatever that is. And I am alga/algae challenged. When is it an ‘it’ and when is it a ‘they’?


An Oyster Thief - Colpomenia peregrina

* * * * *

I mentioned in my last post that I had joined Ispot. Until I posted an Oyster Thief picture there, I thought it was probably an empty egg case from some kind of big fish. Wrong! Now I know. But more than that, another of the Ispotters (Mike Kendall) gave me a link  to an extract from the Bulletin of Miscellaneous Information (Royal Gardens, Kew) 1911 where the arrival of the Oyster Thief along the southern coasts of Britain is described. (He told me not to worry about the slight discrepancy in naming.) Not only that, the very stretch of small coves where I found this one is noted as the place chosen by scientists in 1908 as suitable for observing these olive globes, one reason being ease of access from London. London really is a very long way away from here. In an age of steam trains, it must have seemed even further. However, there was a branch line along here. Local lore has it that there was an informal halt very close to the Oyster Thief Beach (my name) where vegetables from a market garden were loaded onto trains. I’ve not yet been able to find out when this stop operated but there was, none the less, a larger station, closer into town, where scientists could arrive and be within walking distance of their site of interest and in April 1909 another halt was opened as the next stop along. London was far - but the beach was accessible.

However, in the January of 1909, there had been a significant landslide along this bit of coast. I don’t know whether this had an impact on the project or whether scientists continued with their observations regardless. The extract from the Kew Bulletin is but a fragment. You have to ‘belong’ to read further.

It was a busy time for people building and maintaining the railways. It still is. The tracks have long been lifted but nearly all the platforms are still there. The biggest of these is in a cutting and at one end of the old station there’s a road bridge joining the banks. Between one of the platforms and the bridge are the toadstools; at least that’s where they were - for it’s here the workers have arrived to mend and strengthen the bridge and they’ve strimmed the undergrowth to make a place for their machines.

Toadstools and Oyster Thieves have their places in railway history. Sea squirts, washed up with the Oyster Thieves near the old line show us what we might have looked like if we’d been born a bit earlier. Odd that. Not many people will have noticed the toadstools. Who beyond very few have heard of Oyster Thieves, let alone handled them? And how many know the significance of sea-squirts?

Isn’t history odd!

I've never seen nor heard of a sea squirt before. Isn't it great when you get to read a little snippet of local history about your locality.

Rita said...

Very interesting read. Lots of new information for me.
I've enjoyed it very much.

Thanks for the visit to my sites. I do so appreciate those who visit and especially those who comment.

Leavesnbloom - I got very excited when I read that extract from the 1911 Bulletin - probably disproportionately so!

I'm glad you enjoyed the post about the oyster thief and the sea squirts. They were new to me too until I found them on the beach and set out to find out what they are.

I loved this article/post. Fun to read and educational as well. Thanks

Hi Lucy, thank you for your comment. I remember you from Blotanical.
Your post floating in history is very interesting. Coming back, I think it is cruel to keep a fish as pet in a bowl. I have a pond and I watch my goldfish how they enjoy life. In the morning they enjoy the sun, when it rains they play in the raindrops and they love to be in company. They know me when I come to bring them some food, they quickly disappear into their shelter when they spot the silver heron who likes to visit the pond, we all know why!
It brings back memories when I see the charming fly agaric, which we called "Fliegenpilz". It is steeped in "Maerchen". As children we learned very early that it was poisonous and not edible. Anyway it was nice to hear from you and read your posts. T.

Hello Lucy, thanks for visiting my blog. Very interesting post, and I have to agree with some of your observations, fish in bowls don't work for me :-)

Hello Rosie. Glad you liked reading about the Sea Squirts and Oyster Thieves. They aren't quite as lovely to look at as most of the things I show in my posts but I was fascinated by them.

Hello Tatyana. I bought a new laptop recently and it can cope better with the slowness of Blotanical than my old one so I'm catching up a bit with blogs there.

I agree about fish in bowls. It isn't a good place for them. And how interesting it is that so many cultures associate toadstools with magic. It could be because some are hallucinogenic but I think it's because they look like little umbrellas or houses.

Hello Chris. As I mentioned to Tatyana, with a new laptop, I'm able to whiz around and re-visit some of the blogs I have read in the past. It seems we are agreed about fish bowls!

You visited my blog some time ago, I am so glad I got to return the visit. So much to enjoy... Lovely photos of the plants inside the ice. That is not something we get to see down here in the western cape (South Africa). I roamed around in your blog, it was relaxing and full of scenes I would not see otherwise.
Thank you

Great meditations on our place in nature and our nearest relatives--as well as the vagaries of taxonomic identification! I remember a number of never-resolved wranglings in grad school about why only green algae counted as plants (and some people argue even those aren't really). I have a friend, a professor, who tells his Marine Biology students, "Look at a sea squirt and think, there but for the grace of evolution go I..."
