Anguilla anguilla

(Linnaeus, 1758)


Tine Kinn Kvamme Anguilla anguilla,European eel, on the red list, conservation status is critically endagered. Lucky draw I got to see one this weekend. Approx. 1 meter long, curious and friendly. It checked out my camera and torch for a long time :) Drøbak, Norway. Canon G12 in Canon housing. Internal flash+ handheld torch.

Kristian Eikehaug Her i bergen ser vi de på hvert dykk enkelte steder! Heldigvis! :)

Cathal McNaughton Andy, It would be good to get this fish IDed, might not be straightforward though. It came from the gut cavity of a 46cm sea bass. It wasn't within the gut though. It was outside of the gut among the internal organs and it was encased in a whitish sheath which had developed over it. It is as hard as bone, preserved in a way. It seems the bass has eaten this fish and it has somehow burst through the gut wall and entered the gut cavity where it has died and become extremely hard over time. It doesnt seem to have affected the bass adversley. Head seems too thick for a pipe fish, I'm thinking more along the lines of eel or lamprey. The tail appears to have a seperate caudal fin unlike that of conger or anguilla anguilla??? The gill structure might be lamprey like? Any thoughts?

Ronald Surgenor The first photo I'd have thought dragonet, head and mouth shape. Or maybe conermarra clingfish?

Andy Horton Greater Pipefish ?

Cathal McNaughton Its very long and thin Ronald, very elongate for a clingfish or dragonet?

Cathal McNaughton There is an interesting gill structure within and to the base of the head. Rows of ridges which I thought I saw the like of in a lamprey observation on ispot. But the apparent presence of a seperate caudal fin(if Im right about that) would be wrong for a lamprey I think.

Erling Svensen I think Nerophis lumbrisiformis.

Cathal McNaughton Hi Erling, what is that, my google search isnt finding any results at all?

Andy Horton cf. http://www.glaucus.org.uk/Pipefish.htm

David Wilson The mouth is too small for a conemara cling-fish. I thought this was a small dragonet until I saw the long tail, I suppose it must be a pipe fish but too big for N. lumbriciformis.

Cathal McNaughton I'm just not sure it is a pipefish owing to the bulk of the head and what appears to be a significant sperate caudal fin. Not sure, I'll have to get more pics. There just seems top be far too much girth to the head in proportion to the body. I must add, this thing probably looks very different from what it should as its quite shrunk and hardened. Appearances alone might be misleading, eg there is no sign of a mouth structure, never mind a recognisable one.

David Wilson Is this a straightened out seahorse then?

Andy Horton Maybe: http://www.glaucus.org.uk/GreaterPipefish-DD.jpg

Andrew Syvret Can't add anything to the ID debate, but have seen prey items similarly "preserved" outside the gut before, in bass (sandeel) and ling (scad).

Cathal McNaughton Andrew, do they burst their way through the gut wall and then the gut heals? I suppose thats the only explanation really? This might be a sandeel, dunno why I hadnt thought of sandeel. Yes its preserved, feels almost like a piece of wood.

Andrew Syvret I think you're probably right there Cathal. Have seen a good few similar "woody/plastic" objects in the cavity of ling in particular. Most have been indistinct elongated pellets, but a few were clearly fish shaped.

Cathal McNaughton Cheers Andrew, this was quite a shock when first discovered. It was enclosed in a white membrane and looked and felt like bone. Positioned perfectly in the upper centre of the gut cavity and running the length of it. When I pulled it out both the fish's developing ovaries came with it one either side. Having not gutted a female bass before at this time of year, I thought it was a temporary reproductive structure relating to the ovaries. They were well attached to it. The whole thing was very bizarre, it wasnt until I succesfully peeled it that it I realised it was a dead fish. Weird.

Paula Lightfoot Are these juvenile sand eels? About 5cm long, swimming in groups of 20-50 individuals in shallow water/rockpools in the Flamborough no take zone

Douglas Herdson That was my first thought as well.

Paula Lightfoot Thanks! What are the distinguishing features? I thought sand eel because it has a proper 'fishy' forked tail which is just about visible in the photo where the head is pointing left, whereas I thought common eels sort of tapered to a point?

João Pedro Silva You're right, Paula Lightfoot. The tail is never forked in Anguilla anguilla. http://www.flickr.com/photos/jpsilva1971/6964107222/in/photostream/lightbox/

Paula Lightfoot Best close-up of the tail I can manage (it was very wriggly - not easy to photograph!!).

João Pedro Silva By the way, the injured A. anguilla larva I photographed was roughly 10cm long, so I think the animals in your photos have too much pigment for their size to be A. anguilla.

Paula Lightfoot Mine has a very pointy face whereas yours has a more rounded face

Wendy Northway Any idea what these gelatinous blobs on Laminara are?

Wendy Northway I don't know either, but I've not seen this before!

Becky Hitchin Were they actually gelatinous? I've seen Laminaria have a lot of air-filled areas in its stipe that maybe could look like that underwater, maybe

David Kipling What happens if you cut them open - what's inside?

Tony Gilbert Heh isn't that strange, Wendy, I was also finding these yesterday under Trefor Pier in North Wales. I did feel them, they are like hard bumps, I thought they looked like internal growths of some sort. These growths or whatever they are, went through the kelp frond, so you could see them on both side. I was looking for blue-ray limpets - didn't find any though, but did find an Anguilla anguilla.

Tony Gilbert Dark or light patches? Am wondering whether Wendy has photographed the same one as I did, a day later :-)

Wendy Northway Tony Gilbert - yes (well Ariel photoed them) Found blue rayed limpets (well Ariel did - have some photos - will root them out tomorrow) Nice dive, Trefor!

Tony Gilbert Coolio Wend

Rob Spray Species number 4 - The European or Common Eel - Quite a life story!

David Kipling I'm currently reviewing a paper on the ethnography of jellied eel consumption. Is this the same species used for that delicacy?

Rob Spray As far as any commercial fish is properly ID'd yes

David Kipling Cheers. I know In Japan hey distinguish between freshwater eel (unagi) and sea eel (anago).

Rob Spray The 'thing' about Anguilla anguilla is that is has those 7 key stages and distinct common 'names' for the visible ones means confusion abounds. These are the eels that are trapped in rivers.

Jon Chamberlain This may not help with the discussion of sustainable eel populations but: http://www.youtube.com/watch?v=0AckvdGbk4w

David Kipling Anago is Conger (they farm them in plastic tubing) and unagi is Anguilla japonica apparently: http://en.wikipedia.org/wiki/Anago http://en.wikipedia.org/wiki/Unagi

João Pedro Silva During the safety stop all of the sudden I see this guy swimming (in spite of its injury) in front of my mask. Was able to get a couple of shots one of which is completely black and the other is what you see. It was approximately 10cm long. Can anyone confirm Conger conger or is it some other species.

Chris Barrett If the dorsal fin started roughly behind where the pectoral fins are, it'll be a conger eel, but if the dorsal fin started further down the fish (i.e half way) it'd be a common eel

João Pedro Silva Thanks, Chris!

Chris Barrett No problem, hope it helps :)

João Pedro Silva It did help: it should be Anguilla anguilla then.

Kate Lock what an amazing treat ...especially on a safety stop!!

Tony Gilbert Anguilla anguilla is on the IUCN Red List as Critically Endangered, so a good find, well done. I guess this must be an "elver"?
