dabbler Posted October 6, 2016 Share Posted October 6, 2016 There are several studies suggesting that all agglutinated foraminiferas are benthic. I would like to know if there are any published exceptions to that? So for example; can planktonik forams have agglutinated wall structures? I would be happy if you can let me know if there are any studies about this issue. Thank you in advance Cheers Korhan Link to comment Share on other sites More sharing options...

doushantuo Posted October 6, 2016 Share Posted October 6, 2016 it would be hard for planktonic forams to be agglutinating. Link to comment Share on other sites More sharing options...
dabbler Posted October 6, 2016 Author Share Posted October 6, 2016 I agree with you doushantuo, but would this be different depending on the grain composition? Some grains are certainly heavier, but some are not. I know the vast majority of articles even say agglutinated benthic forams, but where this assumption comes from?

doushantuo Posted October 6, 2016 Share Posted October 6, 2016 because not all benthic forams are agglutinating? Link to comment Share on other sites More sharing options...
dabbler Posted October 6, 2016 Author Share Posted October 6, 2016 Yes for sure; there are benthic forams that are not agglutinated, but why don't we see a similar relationship in planktonic forams? "agglutinated benthic forams" make it sounds like there might be agglutinated planktonic forams too. Link to comment Share on other sites More sharing options...
Missourian Posted October 7, 2016 Share Posted October 7, 2016 I don't know the answer to this, but it is conceivable that a planktonic agglutinated foram could exist by using smaller planktonic tests as building blocks. I do know that some benthic forms -- at least -- do this. Context is critical. Link to comment Share on other sites More sharing options...
Foram-Mike Posted October 7, 2016 Share Posted October 7, 2016 To my knowledge, there is no indication, that planktonic foraminifera build an agglutinated test. They drift in the open sea offshore and in the water column, so under common circumstances their habitat does not comprise the sea floor. I would not outrule, that few agglutinated foraminifera may have a planktonic phase in their ontogeny, but do not have any publication on that.

dabbler Posted October 7, 2016 Author Share Posted October 7, 2016 Thank you everyone! I am glad to confirm that there are no agglitinated forams. I was planning to make an argument about that on my research, but it seems like it is not going to happen. Cheers Korhan Link to comment Share on other sites More sharing options...
