Mystery Micrograph #21

Johan got the last one -- it was Colacium, a euglenid of all things! Ok, for this one, you might not get to the genus, but the more you narrow it down, the better. Sorry, 'eukaryote' doesn't count. Warning: It's evil.

Scalebars: 1,2,4,7 - 250um; 3,6,8 - 100um; 5 - 500um. To be referenced later.

Edit 10.05.10 - Hint: The following is a relatively close relative. This one is guessable to the genus level.

Scale = 100um. To be referenced later.

    Might it be Kentrophoros?

    It's a gregarine, right? Gregarina?

    Good guesses but no and no.

    Evil? Is it a Plasmodium?

    Nah, I don't really consider parasites to be 'evil' -- they're just trying to get by like the rest of us...

    Ah, I thought you might be making a play on words. The "Mal" in malaria means evil.

    Oooh, thanks Paul, I didn't even realise that... so Malaria is something like 'evil air'? Vaguely recall having heard something about that before somewhere...very vaguely.

    Do you guys need help there?

    Is it a Trachelocerid?

    Nope. Good job on the obscurity factor though!

    Completely off-topic, but I heard that karyorelictids tend to be really understudied for the reason that...most ciliatologists just happened to live inland! Funny how geography can influence research...

    Another hint: the answer may surprise you. One doesn't typically think of these organisms to look like that...

    Is it a prostoma?

    Nope.

    Think 'shells'.

    How about Nemogullmia?

    Paul: you win! It wasn't Nemogullmia, but, in the authors' words: "Thread-like and other elongate organic-walled allogromiids"; undescribed species. I was basically just looking for "allogromiid'. The bottom one is Tinogullmia sp., another allogromiid. I find it really cool how un-foram-like they are!

    Totally meant to reveal the answer earlier, but was travelling and didn't get around to posting the answer...

    That is really cool! I had no idea that there were forams like that out there.
