    Hi All

    I have got some star polyps that have grown up to some zoas and they seem to be irritating the zoas to the point the zoas next to them aren't opening fully. I was just wondering if the star polyps will completely grow over the zoa in time or if they will just irritate those at the edge of the colony?

    If they causing the zoas to close, then trim back the star polyps as they will prevent the zoas from growing.

    Cut through the star polyps mat with a sharp blade then gently pry off the piece you cut.

    I have had those star polyps completely cover zoas, they are incredibly potent little buggers.

    No they don't open and close in the same pulsing way they just blow around, but they do close up when something like food comes into their mouths. Unlike the xenia they can pull their heads in completely, they have a sort of crust that grows over the rocks that they pull into.

    So this is quite a common confusion in the industry.

    The term "star polyps" is colloquially used to refer to two very similar looking, although taxonomically different species. Interestingly, both are actually encrusting gorgonians.

    The more commonly referred to "star polyps" are Pachyclavularia sp, whereas the "star polyps" in this picture are Briareum sp. The two are easily distinguished as the Briareum sp has "frilled" tentacles around each polyp, whereas they are solid and thicker in Pachyclavularia, and the base is a deeper purple. The two are likely very closely related and often lumped together, but there are key morphological differences.

    @roderigo - they open and close only in the manner that they retracted completely into their mat when disturbed, they do not rhythmically pulse like pulsing xenia.

    Thanks Dane I always thought that its polyps were not as smooth as the ones I have seen on star polyps but wasn't able to find exactly what it was. I have looked through the Briareum sp and can't find one that looks like this either, but I think you are right.

    I think the problem comes in with common names. Too many members of the Clavularia/Xenia/Pachyclavularia/Briareum/Knopia families are all reffered to as the same thing depending on what you want to call it. Differring colours within species also leads to a bit of confusion.

    I agree with Dane, yours do look like Briareum.
    Clove polyps (presume you mean Clavularia) doesnt ahve such a distinct purple mat.

    Sammy I thought it was that for a long time but if you look a the base these have a deep purple crust and also a shorter stem.
    I just found this interesting. View Briareum asbestinum
