Christopher Thorn 31/3/12. Kending area, Taiwan. Photo taken by buddy (he didn't point it out to me:-( so no depth info etc sorry)

Deb Aston Chromodoris geometrica

Christopher Thorn thanks Deb Aston, i was interested by the one rhinophore.. is that a common thing?

Deb Aston the ones I see normally have two rhinophores

Patrik Good I have encountered and photographed a tiny Chromodoris geometrica with only one rhinophore.

Sylvie Omnès you can find very interesting informations about this on the SeaSlug Forum with the key-word "abnormal" :all species of nudis seem to be concerned : less or more rhinophores or gills, cones, etc ... http://www.seaslugforum.net/find/abnormal

Andrey Shpatak Anilao. Gigant frog fish & Chromodoris geometrica Nikon D700+Tamron 90mm. Nov 2012.

Danny Ocampo Nice! Basura or secret bay?

Pat Sinclair Oh wow, a two for one shot!

Marc Levenson hah! Nice.

Andrey Shpatak Basura

Ron Silver Andrey, based on pattern of dorsal coloration and the purple rhinophores and gills, this appears to be C. hintuanensis

Andrey Shpatak Thanks, i am so good spesialist((

Ron Silver It's hard to keep up with all of the changes that are coming rapid fire these days what with all of the genetic testing being done. Technically, this is now Goniobranchus hintuanensis.

Ron Silver I don't mean to be picking on you Andrey, but the Frogfish also needs a clarification. This is the Pink Phase of the Warty Frogfish, Antennarius maculatus.

Kelly Bennett Walkotten 2 for 1. Nice!

Patrik Good Todays stats from two day dives at Southport Seaway, QLD, Australia (23 degrees, 3 to 25 metres visibility): Chromodoris geometrica (3), Analogium amakusanum (1), Chromodoris albonares (1), Hypselodoris obscura (1), Goniodoridella sp. 1 (10+), Goniodoris aspersa (2). Conditions have improved a bit and there seems to be more food around for nudis. I thought I had found No. 99 but it was probably a baby sea cucumber again. Is there a software around that transfers the old nudi names into the new ones?

Ashley Missen Please email to data@nudibase.com thanks Ash - great stats looking forward to the photos - Cheers and Thanks Ash

Gary Cobb NO!!!!!!

Ashley Missen Why Not Gary

Gary Cobb Because you did not write the code!!

Ashley Missen ME!!! - I thought there would be an app for that

Gary Cobb Yes you data base man!

Patrik Good Stop programing code. Our priority is to get a portable/handheld DNA sampler device for branchers with wireless upload facility into our individual databases possibly with a remote backup onto nudibase :-).

Ashley Missen Did you want a special housing for the underwater DNA Scanner

Ashley Missen Maybe a barcode printer on it too so the next time someone see it we can find it in the database

Patrik Good A scent emitting, nudi attracting housing would do if that's on special at the moment. An intelligent barcode on the nudi should contain camera settings based on the branchers equipment while considering lightening conditions too, if you are at developing such a machine. But the end stage has to be that we all have a DNA mixer, so we can all design our own nudi.

Ashley Missen As you Wish! should be ready by Friday

Deb Aston Boys and their toys!!!!!

Patrik Good Alright, can we have that in pink and purple, please?

Ashley Missen Really!!! Pink and Purple - is that so the nudi can't tell what you are up to - nudi camo??

Patrik Good Maybe that too, but also so that the girls are tempted to playing with our boys toys.

Blogie Robillo Chromodoris geometrica. Depth 24m; length less than 1cm; Marissa 1 dive site, Samal Island, Philippines.

Blogie Robillo I waited for a couple of minutes for its gills to come out, but it never did...

Blogie Robillo Chromodoris geometrica, 20mm, 13m deep. East Point dive site, Bgy. Tagpopongan

Blogie Robillo Chromodoris geometrica, each of them about 1.5cm long, spotted very near my previous post (G. cruenta) at 15m.

Patrik Good Seaway Cruiseship Jetty, 30/4/2012, size 5mm (sitting on fishing line), 3 metres depth, 23 degree. Is it a cruiseship eating nudi? Does anyone know what it is? I think it might be too ugly to be a nudi but I still collected it.

Deb Aston My guess is a baby sea cucumber. Cruiseship jetty over my dead body!!!!!

Patrik Good Thank you, Deb. Found Analogium amakusanum (1), small Chromodoris verrieri (1), small Chromodoris geometrica (3), huge Flabellina rubrolineata (1), lots of Goniodoridella sp. 1 (biggest ever). Also collected some other fluff and nudi spawn that I will investigate tomorrow. Analogium amakusanum definitely made my dive.

Deb Aston still waiting for no 100!

Patrik Good Goniodoridella sp. 1 (http://www.nudibranch.com.au/pages/9667b.htm). 9mm, 3 metres, Seaway SW Wall. Where have all the Hypselodoris obscura, Ceratosoma tenue, Chromodoris daphne/verrieri and the rest of the excessively abundant day-nudis gone? There seems to be no food source, all rotten away during the past few weeks with all fresh water instream. Now, there is one species emerging in surprising numbers and that I rarely spotted before, the Goniodoridella sp. (various sizes 8mm to 18mm). Anyone know what they are eating? Wonder how long it will take for the other nudis to be back again. The photo shows one individual saying hello to another one.

Gary Cobb Nice finds Patrik! Eminem sings....food sources they come and go...

Patrik Good :-) Thank, Gary Cobb. Food sources going for some species obviously means food source coming for other nudi species. Well, maybe the nudis were just missing the queen of the Seaway and decided to go travelling too.

Vishal Bhave Is it wide spread ? as i have specimen here from Ratnagiri !!! :D

Patrik Good Vishal Bhave, it is quite common in South East Australia. I have found it on several occasions on Old Woman Island and Southport Seaway, QLD. I have no idea how widespread they are on a global scale. Maybe some other nudi lovers have more info. Last dive this was the only species I found. Food source for other nudis have recently died with all the rain and temperature is relatively high. This nudi was abundant (more than 15) and probably busy reproducing. It would be interesting to know the reason for their appearance in numbers.

Patrik Good Hi Vishal, just realised that you must be a researcher. Are you planning to do a paper on this species? Where is the diving/collecting done in Ratnagiri? Is that Mirya creek or the open sea?

Patrik Good Scanning the Seaway again for 4 hours yesterday. Due to a lack of boat traffic (don't we love severe weather and coastal flood warnings?) I could safely dive the shallows too. The Goniodoridella sp. 1 are still everywhere (I stopped counting and taking pictures). Still no other nudi to be seen except for a tiny Chromodoris geometrica at a quite unusual spot inside a black sponge. Found a few beaten egg masses too. If anyone is diving the Seaway at night please let me know if things look different.

Vishal Bhave I have collected that in Rockpool, in Ratnagiri.

Patrik Good Just an update on these critters. They are absolutely loving the strange conditions we have at the moment. They have grown physically in size and in numbers. They are everywhere. You can see them stretching out their backflaps - it looks like they are sunbathing - and I think I even spotted two of them reproducing. All the other nudis seem to still be gone (only one egg mass found on a two hour dusk/nightdive), along with their food.

Patrik Good Update on these nudis. They are still around, some in twos but not that many and some don't look healthy any more.

Patrik Good Update on the Goniodoridella sp. at the Seaway. They were abundant, healthy looking and mating again last week. Today, I only found one individual and I can certainly say that they are not as visible any more at the moment. I wonder if their mating had been successful at all. These critters keep surprising me.

Patrik Good Update on the Goniodoridella sp. at the Seaway. They are still around, more visible again, and regularily found in numbers. They are looking healthy and some are quite big. My theory about the wing flapping is definitely falsified. Saw a wing flapping individual and no other individual on the same rock. Some individuals have brown dots on them and some have small white but clearly visible pustules/elevations.

Ryan Pearson My mate is looking for ID on this species. Any ideas guys?

Ashley Missen Picture please

Ryan Pearson Weird, the link is showing on my screen. https://www.facebook.com/photo.php?fbid=10151153856125223&set=a.200381035222.253299.782525222&type=1&ref=nf

Ashley Missen On my view even, the link can't be viewed just comes up with an error- Facebook gremlins

Frank Wehner @ Ryan - the link doesn't work

Ryan Pearson Ok, I think he's going to join nudibase and post it himself :) Sorry guys.

Nicolas Rakotopare Hi guys, here is the actual link https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/383265_10151153856125223_782525222_22269004_1115240065_n.jpg :)

Frank Wehner Chromodoris geometrica

Ryan Pearson Nice one Frank

Nicolas Rakotopare Thanks for that :)

Ashley Missen Definitely Chromodoris geometrica

Roy Arthur David Lontoh Agree with Ash...

Gary Cobb Without a doubt!
