  • The Sea Slug Forum - Ascidians (Sea squirts, Tunicates)
    Many ascidians form colonies In the intertidal zone, many of the fleshy, brightly coloured patches under rocks or in shaded crevices are ascidian colonies PHOTO A is of a solitary ascidian showing the inhalent and exhalent siphons PHOTO B is a colonial species in which each individual animal (zooid) retains its exhalent siphon
  • The Sea Slug Forum - Nembrotha kubaryana
    Both species removed antifeedant compounds from the ascidian and stored them in their own bodies, exudung them in a slimy mucus when disturbed for their own defence [N kubarayna has also been reported feeding on another dark blue ascidian which has been identified as Sigillina signifera Perhaps Atapozoa is another name for Sigillina
  • The Sea Slug Forum - Ascidian
    Did it squirt out some water when you touched it I am pretty sure that your animal is an ascidian or Sea Squirt, quite unrelated to slugs It seems to be attached to the rock at one end and has a pair of openings at the free end at the bottom of your photo I have posted a page on ascidians Have a look at it for some background information
  • Okenia rhinorma feeding - Sea Slug Forum
    The ascidian would appear to be a Molgula sp but I have yet to identify which of the several local Molgula species it is The first image shows the nudibranch and the track it took to the ascidian The second image is of the nudibranch shortly after beginning to feed and the third image is of the nudibranch well buried in the ascidian
  • The Sea Slug Forum - Goniodoris meracula
    The foot is usually folded up the sides of the hole so the slug's body is effectively surrounded by its own foot In some instances the exit entrance hole in the ascidian colony is smaller than the slug, suggesting that it has grown in size since entering the ascidian colony In these cases the slug is almost invisible from the outside
  • The Sea Slug Forum - Nembrotha chamberlaini
    Here is a Nembrotha chamberlaini from the Philippines feeding on an ascidian Size 3 cm, depth 14 m, Nov 05, 1998, Panglao Island, divesite "housereef" Erwin Medslugs Koehler@t-online de Koehler, E , 2000 (Sep 13) Nembrotha chamberlaini feeding [Message in] Sea Slug Forum Australian Museum, Sydney
  • The Sea Slug Forum - Velutinidae - are they sea slugs?
    It preys on compound ascidians, on which they are very cryptic (a compound ascidian appears to be present in the lower left of Carmelita's photo) Not visible in the photo are the thin head tentacles with eyespots at their bases I have also sent photos of a couple of other Californian species [messages #13810, #13816] Best wishes, Jeff

  • The Sea Slug Forum - Austrodoris kerguelenensis
    Concerning feeding I agree that it would be most unlikely that your animal is feeding on the ascidian or forams on the surface As I mention on the Fact Sheet, Barnes Bullough (1996) report that it feeds almost exclusively on Dendrilla antarctica Nudibranchs tend to perch in some strange places at times Best wishes, Bill Rudman
  • The Sea Slug Forum - Hallaxa michaeli
    The lower photo is a single stalked ascidian with one of these at the base The upper photo is of a group of the stalked ascidians with another one of these at the base we think, it is a bit overgrown and we are not confident of our knowledge about these particular ascidians
