Ardeadoris egretta

Rudman, 1984

Jon Chamberlain Ardeadoris egretta at B3 (Hoga, Indonesia), previously seen freeswimming and settled on a hard coral before curling around in a circle. Odd behaviour, perhaps it wasn't too keen on hard corals (ahem - James?)

James Chasty Odd behaviour you say? Then why choose to land on hard coral in the first place? Sorry, choice is too anthropomorphic a term to apply to poor little nudibranchs...Why ASSOCIATE itself with the hard coral in the first place? Out of desperation? Chance? Hydrodynamic influence? I need answers!

Jon Chamberlain See you next year then...

Chad Tamis James your suggesting it choose to land on hard coral which is beyond unlikely. Even if following some sort of chemical cue it would be acting in a much more general sense (maybe directional?). Free swimming is generally associated with a defense response which isn''t an odd behaviour at all. He probably didn't care where he landed as long as he is no longer in direct physical danger. I curl up in a circle all the time when I feel threatened...

James Chasty Hey Chad, sorry but my response was a bit dramatised and a bit of an in-joke with Jon regarding my dissertation. As I didn't observe a swimming response during my time on Hoga this was a thought regarding what path nudis take when moving. We wondered whether they would move 'as the crow flies' towards food or conspecifics or if they found certain substratum types deterring, e.g. hard coral due to it's abrasive nature of perhaps their nematocysts. Thanks for your insight anyway :)

Chad Tamis Nudibranchs don't fly James...

Jacqui Hann ...it was the first time I had seen a free swimming nudi! This guys was actually curling into circle mid water.

Ashley Missen actual think this one is Ardeadoris egretta - Rudman 1984

Jun Tags what would be the differentiating factor? they are almost the same, hard to identify, thanks

Reed Nescher I think this is a Sea Goddess and the biggest I have seen, again in the Solomon islands. https://scontent-a-sjc.xx.fbcdn.net/hphotos-prn1/1176356_10201370908707410_82059205_n.jpg

Lindz Warren I am not sure where you find your 'common' English names but these are not in fact common at all. You will probably find it more useful to use the accepted (and commonly used) latin (scientific) names. ;-)

Lindz Warren This is Ardeadoris egretta Rudman, 1984 if I am not mistaken.

Janna Lorentzen Photo from the Philippines, Cebu. Not the best photo I have of the nudibranch, but the little shrimp is presenting itself nicely. ;O)

Gary Cobb This is the beautiful Ardeadoris egretta Rudman, 1984

Janna Lorentzen Thanks Gary for identifications. The nudibranchs only cross my way while we are searching for ovulids and cowries. So I cannot resist to make a photo but I am not deeply into identifying them. ;O) But I think, I have to improve because I love to photograph them..

Sven Kahlbrock Nice shot Jana ;-P

Gary Cobb Your new job is to find them! Why? Because they are to be loved!
