Hoplodoris grandiflora

(Pease, 1860)


Karl Fehlauer Robb's Jetty, Coogee, Western Australia Depth 4m Size - 20cm +

Karl Fehlauer Not sure of the Id for this guy - he was about 20+cm in size and was the first time we have seen one of these at this site.

Chris Cunnold Not sure, is it Hoplodoris grandiflora? I saw it too a few days earlier, it's very large.

Gary Cobb We are calling this Dendrodoris sp. Karl may I include this photo in the upcoming Nudibranch ID Australia/New Zealand App update?

Karl Fehlauer Gary Cobb - no probs happy to help. Sorry it isn't the best image but it was so big that with the 60mm macro I had to pull back a fair distance.

Gary Cobb Thank you Karl for your help! The critter is magnificent!

Gary Cobb After a little research this is Discodoris cebuensis Bergh, 1877

Damian Hofman Hoplodoris grandiflora?? Clifton Gardens 3m depth and about 70mm long.

Gary Cobb This looks like Tayuva lilacina (Gould, 1852), previously known as Discodoris lilacina. It can not be of the genus Hoplodoris because the mantle does not have large, rounded tubercles that decrease in size towards the mantle edge. And the mantle has been autonomised. A ventral view would be very helpful. Your animal's mantle is covered with small papillae and rhinophores have a raised rhinophoral pocket.

Mel Turner Need some help with an ID please... Seen in South Fremantle, WA (Robbs Jetty). In about 5m, approximate size 20-25cm long (and about the width of a CD). At first thought this was Hoplodoris grandiflora, but have since had another suggestion that this may be Discodoris cebuensis. Thanks in advance! :-)

Sonja Ooms I don't think it is the discodoris cebuensis as they have patches of tubercles along its margins and on its midline are usually tipped with white and the central tubercles in each patch are dusky violet. The white pigment is variable in extent and there are also three enlarged white tubercles on each side of the midline. As for the hoplodoris grandiflora, it seems that their size is usually smaller than the one you spotted. On the other hand, the pustules are often based in a white circle which is the case here. The mushroom dendrodoris would also fit (Dendrodoris sp.) but they are usually seen in the Philippines and the tubercules have a reticulated pattern which I do not see here.Would you by any chance have a photo of the gills?

Mel Turner Thanks for your help Sonja Ooms - will dig out some more photos and post them ASAP
