Lovely observation ABK, nice fish. There were some lengthy discussions about clingfish classification and recent developments during 2012 on iSpot and I think the conclusions drawn, after much debate was that all UK and Irish clingfish are now considered Lepadogaster purpurea.
See thorough discussion on the subject here:
EDIT- I realise that clingfish has been left as Lepadogastor lepadogastor but the discussion seemed to conclude with all clingfish in UK waters being L. purpurea.
Very interesting find; I've never seen a clingfish on the Gower yet & the New Naturalist bk "Gower" (2006)doesnt list any, but there's a 1987 fishlist at http://welshjournals.llgc.org.uk/browse/viewpage/llgc-id:1272866/llgc-id... (& click on PDF symbol for readable versn)which describes sp's new to Gower (Includg Apletodon microcephalus, a clingfish),+ at end a complete list of Gower fish (with only that clingfish).
Thanks for comments and links, all very interesting and a bit confusing.
I could be wrong but I think that all UK Clingfish that are Lepadogastor lepadogastor/purpurea are considered to be L. purpurea but there are other species of Clingfish in UK waters . I am very familiar with the Shore Clingfish/Cornish Sucker but I considered this to be an entirely different species of Clingfish, possibly the Two-spotted Clingfish. Does anybody have any thoughts on this.
There are actually 4 uk species of clingfish in the uk, but 2 are very alike,Diplecogaster bimaculata & Apletodon microcephalus, now known as A. dentatus,the small-headed clingfish. (why I'm hesitant in agreeing).But for your 2-spot see http://www.marlin.ac.uk/speciesinformation.php?speciesID=3176 & it says the 2 hard to distinguish but can be by looking at the teeth. (& describes them)

The other 2 clingfishes Lepadogaster purpurea & L.candollei differ in having duck-like mouths.
They (D.b. & A.d.)can change colour to suit background
The clingfish controversy was about 2 nearly related, L.purpurea & L.lepadogaster, both of which are in,eg, Portugal but only 1 in UK
Hi Chris and ABK,
It seems I have completely misunderstood the lengthy debate on clingfish on here last year . I get it now, ABK, sincerest apologies for my misinformation above. The debate was over 2 closely related- I have read- 'all Lepadogaster in uk are L. purpurea'- and somehow taken it to be all clingfish.
Chris, yeah that tiny clingfish in the pic of mine used by MarLIN, I have it on iSpot but my ID is based on the above described misunderstanding, ie I have IDed it as L. purpurea despite what MarLIN decided it was. My ID may need some revising now.......
Thanks for spelling it out.
Those at MarLIN must be quite sure that juvenile one I found in 2010 is Diplecogastor bimaculata to have used it on the species page. I wish I knew what makes it that over the other, does anyone know?????
They didnt see the teeth.
Here it is, the ID and the comments I have made are nonsense in the light of the above info!
Thanks once more. If I am lucky enough to see another I will try to have a look at its teeth, if this can be done without hurting it!
I guess marlin's decision is up to them, Cathal; your pics were certainly detailed; & they did say "hard to distinguish" not impossible.However they're not infallible, as last night I found in their identification of white piddock at http://www.marlin.ac.uk/speciesinformation.php?speciesID=2728 that the 3rd pic is (whoops was) of common piddock (& i've emailed them).Both these 2 clingfish are described in species-identification.org ,but too technical for me.
...they've emailed back & shifted it already!
Good work Chris, yeah I wonder have the sea scorpions been sorted yet? They have a T. bubalis or 2 under M. scorpius.
I think I should probably put up an ID of D. bimaculata under my one as MarLIN are confident enough to have used my image on their page for the species. I should ask them what determines its species.
This is the sort of Post that does iSpot credit (364 reads). Two excellent pictures and a good discussion. Despite there being no positive ID there is merit in the post.
If one reads the comments, then the conclusion might be that pictures are not enough and closer study is required - the downfall of many an excellent post!
>>WoRMS<< much prefers the Alternative Diplecogaster bimaculata bimaculata but that was last edited in 2009.
>>Apletodon dentatus<< is seen as an entirely different species.
For us mere mortals, looking at and counting teeth is a bit too daunting, but may be necessary.
Andy I do think you should actually separate the two in the ID panels. Of course a Dual Identity would never be accepted by iSpot and so, few of us can agree.
If what Cathal is say is true (if I read it right and I've read the available evidence in the links) then maybe we should accept "all clingfish in UK waters [as] being L. purpurea".
But what confuses me is that, by all accounts, the Two Spotted Clingfish should be what is says on the bi-maculata tin and which can be seen here http://www.marlin.ac.uk/speciesfullreview.php?speciesID=2568 in pictures by Keith Hiscock and Judith Oakley, not to mention (but I will) "a blue spot outlined in red or dark brown behind each eye". This evidence suggests that the picture in this post is likely to be Apletodon dentatus. That is probably where my agreements would go
Origin 14th Sept
I have begun a project - that is JoC and I.
We'd like some posts, say up three, for now, with easy-to-fathom pictures, a little descriptive text and a fairly definitive ID (or mystery) - a long Comment trail is fine.
Will you contribute? Can you find one or two suitable posts (you'll know the sort) and Tag them ProjectM1 (max. three for now). They will auto-load to the project.
Simply remove the tag if you want out any time.
It is a new idea, an experiment, may not come to fruition and may yet change out of all proportion!
It is not solely for invertebrates.
We'd appreciate some suggestions or recommendations - some stuff may be best done via personal email - I'll come to that later.
PS note that you have now had 377 (today) reads, so I think the project might be paying off.
