I know nothing about androids but reckon you shoold report it in the forum 'report problems' (Clk 'forums' tab at top of this page,clk 'report problems' clk 'post new topic' (they're usually answered quite quickly)
thanks Chris, I have reported to Rachel from happy team but also pit on forum now, thanks for suggesting- be interesting to see if anyone else suffers same problem! ta, Tom

...can we be certain this is not Aeolidiella glauca (reddish) or Spurilla neapolitana? Please.
As far as I can see on-line, Spurilla neopolitana is a circumtropical species so needs warmer waters. I can find no record for British Isles.
The photo does not provide enough detail for me to distinguish between A. papillosa & A. glauca, but others may feel more confident. So maybe I should remove my agreement. Perhaps Tommoses has additional photos?
It definitely is Aeolidia papillosa which isn't called grey seaslug for nothing; there are no A. glauca such a dark colour, & just look at the size, 6cm where A.g. only reaches 4.5cm. See http://ppear19.wordpress.com/2013/01/29/mini-mouse/
No, no, no Jo.
I was not casting doubt, I was asking how we can be certain. In iSpot, I can see that "how can we be certain" is usually seen a challenge!
S.neopolitana is a no - you are right (so far and for a while yet!)
Aeolidiella glauca is recorded fairly well in UK including Broadhaven specifically and one record for Orkney. They are very similar and this picture is not as clear cut as say.. my 'drowned puppy'.
But to be honest, I might not be able to separate it from Aeolidiella alderi either (simple inexperience) - though that one ought to be paler.
Twas Chris's Comment (" definite 'as sure as'") that drew me in and from that him I expected a swift 'informative' reply..
I have not agreed yet of course.
Added moment later after seeing Chris's (thanks Chris, as expected, straight to very good reasoning)
Earlier, when I looked carefully at the photo. I wondered how big it was. Then, when Chris said 6cm - I looked again - and saw the words 6cm. So, A. papillosa it is.
From Hayward & Ryland - The Aeolidiidae are nudibranchs with cerata in rows, each containing lobes of the digestive system, and terminal cnidosacs storing unfired nematocysts obtained from (anemones which are) their prey. That's neat.
Wow. Thanks for all that discussion thread all! Unfortunately I don't have more pics (but someone else I was with may do- will ask....) feeling paranoid I may have overestimated the size now (did not measure, just estimated...). Sure it was more than 4cm though. Did have definite reddish ness to it however. I'm gonna have to get more rigour in my spotting.....
Tom - the size thing is interesting. It is common for people mis-estimate sizes - we all do. I meant to say THAT before but it would have seemed 'rude'.
Only last week did I respond to someone who 'estimated' size quite wrongly, spoiling an otherwise 'perfect' ID.
You will see, if you look at my postings, I often ruin otherwise good pictures by including a scale item.
Whilst interesting underwater (where I no longer go), EVERYTHING looks bigger, it is not difficult to have an item of scale ready. But I know too well the excited feeling when you find something and want to take a picture!
Good posting then..
and dj often puts in a coin for scale. However, it's not a matter of life and death - just another bit of useful information towards getting a correct id. Keep posting your photos,
