Seaslugs eat ascidians occasionally,and this ascidian’s cosmopolitan,so…;a ‘whatsit’ @hotspot Nville SA dsm i47058
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.
…(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.
….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.
….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.
….’.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….
…at least we can now all agree that there’s no hint of denial lurking anywhere inside my head!
??Graham Short put me up to this??!!(that,my friends’,is a big lie!)
I close with (verbatim)a quote I read somewhere which seems pertinent,tho’ I think the original quote referred to our species’ war-mongering nature:’There is perhaps nothing quite so frightening as a person who is so sure he is right that nothing can convince him/her otherwise’.
