Trapania pallida

Kress, 1968


David Kipling Two UK examples of confirmed (by Bernard) Trapania pallida. Apart from missing the patch between the rhinophores these are very similar to the one shown by João Pedro. White markings: - line along tip of tail - blob on top 1/3rd of rhinophore - marks on the two sets of recurved "horns" (by gills and by rhinophores) - white mark at end of oral processes - white marks on tips of gill plume We're missing most of those blobs of solid white, and instead George's animal is covered fairly evenly with light yellow spangly dots. So apart from having the generic body plan of a Trapania the colours don't match ...

David Kipling (shifted to the group because I erroneously posted it on my own wall, duh-huh).

João Pedro Silva The few I saw also had a white mark ahead of the gills and another one between the rhinophores: http://www.flickr.com/photos/jpsilva1971/7409000024/

David Kipling The white looks a bit more extensive as well, as if a bigger brush was used. Mine are more British and restrained ;)

Terry Griffiths Only ever photographed one in the Torbay area nice pictures.

George Brown Hi folks, is this Trapania pallida? Unusual white mottling. Found off the island of Lismore, Loch Linnhe, west coast of Scotland. Depth 16m. 56deg 28.235'N 05deg 35.135'W.

João Pedro Silva I've only seen it twice and it has only been found in Portugal last year, so I cannot say I'm really familiarized with this species. The individuals I've found hadn't that scattered white pigment all over the body and had very distinctively pigmented branchia, rhinophores, processes and also a spot between the rhinophores and another smaller ahead to the branchia. This really doesn't look like the ones I shot: http://www.flickr.com/photos/jpsilva1971/6241752065/

Jim Anderson Excellent find George - it certainly is Trapania pallida.

George Brown Thanks Jim. Just for the record I found another one just south of Ardnoe Point in the Sound of Jura. Not a good photo. :o(

David Kipling It's certainly a Trapania with those recurved "horns" at the base of the gills and rhinophores. Like JP, I've not seen it in that colourway (and there are multiple Trapania species).

João Pedro Silva A couple of months after this was post I shot an unusually pale T. tartanella in Sesimbra: http://www.flickr.com/photos/jpsilva1971/7706913718/ This is the most commonly found Trapania here in Portugal (although there is always the doubt regarding individuals found here being T. tartanella or T. hispalensis). And it does have some variation namely in the presence of those white dots on the body (I'm saying this because all T. pallida I've seen, including another one found a couple of weeks after this post, had no scattered white dots). More candidates for molecular analysis?

Simon Exley Jim, it was at the same site I did with yourself and Craig.

Henrique Nascimento Catarina just a small nudi, Trapania pallida (white), with another one even much more small..... Cuthona ocellata (blue & yellow)...4 Farilhões (Berlengas) - Portugal 20130710

Ron Silver Coloration doesn't seem right for C. ocellata. Looks like C. yamasui except it has not been found in this area to my knowledge.

Henrique Nascimento Catarina Ron, has you know, I'm not an expert...... it was João Pedro Silva who told me the name C. oceliata... maybe he read this post and can see if is OK or Not ? he is the expert not me, I just love diving and photo.... the names :(.... But thank you very much for your advertise.....

Ron Silver No criticism meant, Henrique. Joao is an expert, so let's see if he adds a comment. Thanx for posting your photos.

João Pedro Silva It's Cuthona caerulea :) No C. yamasui in these parts.

Ron Silver Thanx João Pedro Silva

João Pedro Silva 5 Trapania pallida found yesterday in Farilhões, Portugal. This species was first seen here in mid 2011. I've seen it 4 times since (including yesterday).

John Sexton Are you going to show it to me on the 7th?

João Pedro Silva Whatever I find, I'll show you, John :)
