Philippines, Negros Oriental Is., April 1994, depth unknown, size about 5 cm. PHOTO: Fred H.-H. Harms.

Characterised by the cream coloured body with brown spots, patches and longitudinal bands. the fills and rhinophores are also dark brown. It differs from other species of Nembrotha in having a non-denticulate concave-edged blade on the central tooth. One specimen was also found on an arborescent bryozoan, which is unusual for a genus which normally feeds on ascidians.

Nembrotha mullineri from the Philippines

Hi Bill,
thought you might be interested in this Nembrotha mullineri as the creature seems interested in the clear, blue speckled, ascidians in front of it.

Dear Bill,
I am looking for ID on this nudibranch.

Dear Chris,

This is Nembrotha mullineri. It is interesting to see the commensal shrimps. I am pretty sure they are Periclimenes imperator, a species usually associated with Hexabranchus sanguineus, but also found at times on  a variety of large dorid nudibranchs and pleurobranchs.

Best wishes,
Bill Rudman

Food of Nembrotha mullineri

Bill,
Thanks for the ID. I don't have another picture of the slug on the ascidian, but here is a separate photo of the kind of thing it was feeding on. Hope this helps.
Best regards,

Dear Anne,
This photo certainly does help. Now I can see the ascidian in your earlier photo. It should be possible to identify this stalked colony. It has similarities to one identified by Gosliner, Behrens & Williams (1996: Fig 1068) as Oxycorynia fascicularis Drasche, 1882 and report that it is the food of Nembrotha lineolata and N. chamberlaini. As far as I can determine this is the first information we have on the food of N. mullineri.

Nembrotha mullineri from Indonesia

June 13, 2002
From: Anne Owen

I have just visited your website for the first time, following a recommendation from Scott Michael - it's great and I'm pleased to have found you!

Could you help ID this nudi please. It was found at about 30-40 feet inshore in Horseshoe Bay, Rinja, Komodo National Park, May, 2002. Not a good image as it was wrapped around a colonial ascidian and I declined to disturb it. Looks much like Nembrotha, but interesting deep red instead of more normal green
Hope you can help.

Dear Anne,
This is indeed a species of Nembrotha, in this case Nembrotha mullineri. By co-incidence we have just had a number of messages showing the considerable colour variation in this species. I guess if it was wrapped around a colonial ascidian, as you report, it was eating it. Species of Nembrotha feed on specific ascidians. If you have a look at the page on the green Nembrotha milleri you will find quite a few photos of it feeding on ascidians. However there is some doubt about the food of this species and I am not sure from your photo just what it is on. Have you a photo which shows the 'ascidian' more clearly? Even it is not a good photo of the slug, it would be interesting to be able to identify what it is on.
Best wishes,
Bill Rudman.

Erwin Köhler's N. mullineri

June 11, 2002
From: Nishina Masayoshi


Dear Bill,
Nembrotha lineolata, N.livingstonei, N.rutilans and N. mullineri are all similar for me. I thought the one of distinctive external feature is the white patch between the rhinophores. Especially N.livingstonei and N. mullineri are similar. But N. livingstonei has the cross shaped patch between the rhinophores. Is this a sure way to identification?

Erwin Köhler's N. mullineri from Negros, Philippines, looks almost like N. mullineri but has no patch. So the animal may be something unusual type as N. mullineri or looks something special for me. I've never seen such a dark N. mullineri before.

The attached photos are both photographed at Kungkungan Bay in the Lembeh Straits of Indonesia.

Dear Nishina,
Thanks for these photos. I have added some more from Erwin today which help clarify the variation in N. mullineri. I must admit that the species you mention are a bit confusing and I am afraid there is not a lot of variation in internal anatomy between species, so I suspect that in the end we will need to have a much better understanding of how colour patterns vary within the group than we do know before we can talk sensibly about how many species there are. Photos like yours and Erwin's therefore are very valuable.
best wishes,
Bill Rudman

Dear Bill,
In answer to your comments to my last message, here are 3 more colour variants of (what I think to be Nembrotha mullineri) from one dive at the Philippines, Negros Oriental Island, Lipayo, divesite "Pier", 03 March 2001 (same dive as the one with the mating pair). I think with the shots I sent with a separate message they show an almost pure brown variant (which looks like a wrong colored Nembrotha milleri), a variant with very dark cream spots and some variants with brighter cream spots.

Data:
Upper Right: 64mm, 15m depth
Lower Left: 66mm, 14m depth
Lower Right: 58mm, 16m depth

Re: Nembrotha mullineri from Cairns

From: Wayne Ellis

Morning Bill,

Spoke with Tas last night. The photo of Nembrotha mullineri is definitely from off Cairns, north Queensland. This means N. mullineri and Hoplodoris estrelyado have now been sighted in East Australian waters. (See Australasian Nudibranch NEWS #10 Page 2 for further details).

Nembrotha mullineri from Cairns?

July 22, 1999
From: Wayne Ellis

Hi Bill,

Attached is an image of Nembrotha mullineri from Tassie Weinreich in Cairns. (See anNEWS #10) There is some suspicion this species may actually be from Western Australia. Tas photographed it at an aquarium I understand and the actual source of the beast is a mystery at this point.

Localities are a bit of a problem with aquarium animals. It would be nice to know where it actually came from. However it is a good dorsal photo.

Thanks Erwin,
I'm pretty sure this is Nembrotha mullineri which was recently described from the Philippines. Nembrotha mullineri is the only known species of the genus to have a colour pattern consisting of only a cream background and brown patching or lines.
