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.

  1. It's a gregarine, right? Gregarina?

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

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

  4. 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?

  5. 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...

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

  7. 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...

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