David Muirhead I have difficulty distinguishing between two similar looking moderately large pipefish species that are both common in similar terrain and shallow depth here in South Australia:this one in the image is probably a Briggs Crested,however the truncal markings would easily fit with the Ring back Pipefish.

davem Probably Bridled Leatherjacket,female/immature,but I am not 100% certain;these smaller seagrass-associated leatheries in SA can be tricky to ID to species level.
davem Hmmmm...

davem This species,the Common Brown butterfly,is indeed common right across Southeastern Oz.This is a female,the males are smaller,w darker even more cryptic colours and patterns,and strangely seem to emerg

davem I gather from browsing various expert -based nudibranch databases,books etc,that at present the nudibranch species globally for which the target dietary species are established beyond sig doubt,the majority eat sponges or hydroids,with a minority preferring bryozoans,anemones,algae,and a few have more peculiar or highly specialised niche diets eg other nudibranchs,small crustaceans,and sea pens.
davem ...(further to above)....However,there's still much to learn,and I've been wondering if Botrylloides leachii may have an as yet undiscovered seaslug species which eats it hence wld mimic it.
davem ....that said,I agree with the several experts who told me this image features merely a damaged compound ascidian colony which perchance closely matches in outline the typical nudibranch profile,but is definitely not an actual seaslug,ie the similarity is mere coincidence.
davem ....The only problem I have now is this:I'm a notoriously irritating ,often seemingly unrepentant individual,who keeps saying 'experts are experts for the very compelling reason they know what they are talking about more than generalists like myself,so we should as a general rule accept their identifications of such critters,until we can provide specimens that challenge and even refute that ID.
davem ....'.or,to put it simply,my science brain says I'm fantasising,almost'inventing non-existing species',based on such flimsy 'evidence' as this image,yet my emotional or 'reward-seeking',dreaming,primitive brain parts(if,indeed,I have a brain....some of my colleagues quite justifiably speculate often on this latter question!)...will not let me 'let go' and move on....

davem Several pipefish experts have told me they think this is a Port Philip Pipefish,or other Vanacampus species,but at least one such expert (entirely appropriately,as this old slide film image is slightly unsharp even at higher resolution,effectively making a firm ID impossible in absence of a collected specimen to accompany it)...
davem ...has qualified his response with 'please take sharper and more side-on images so we can do accurate dorsal fin ray counts,body ring counts,etc'..
davem I've been using digital camera since shortly after the above image was taken,but so far,at this particular dive site ie 'hotspot' Normanville,I've not found another pipefish exactly matching this one.So I'm still in the dark re definitive ID.
davem However,the (barely discernible,admittedly,but they are real) dermal flaps present on the pipefish above do make me wonder if,just maybe,it's a Tiger Pipefish Filicampus tigris,subadult or juvenile....??
davem The best Syngnathid ID tomes at my disposal never mention dermal appendages/flaps wrt V.phillipi,as I recall.
