View Full Version : The little monsters in our tank (Beware: Science Pictures Inside!!!)

A little while back I was staring at the glass in my tank watching these bugs smaller than a pinhead bomb around the glass at a pretty good pace. A quick back of the napkin calculation said that these little buggers were running around at the equivalent of a human running 150 km/hr! (~20x their body length per second) "What are these microscopic speed demons?", I thought.

So, doing what any other normal person would do, I spent half an hour trying to catch one, dried it, gold coated it, and tossed it in a scanning electron microscope (SEM).

This is what speed-racer looks like close up!

***I did this pretty quick and half-arsed, so pardon the dried salt crystals and other junk in the pics***

So cool. And to think 150 million years ago those things were the size of a VW

Hahaha. Ya, it's pretty sweet (I actually have 3 at my disposal). It's pretty fun putting random stuff in there while doing my actual work. This guy is pretty tame compared to some of the other stuff I've stuck in there.

I think next up is one of the million pods running around my tank.

So jealous of your SEM... Do you have access to a TEM as well?

I do! But I find them pretty unexciting:razz: For high mag work I prefer the FESEM. The SEM and FESEM are like cameras, where you can compose nice shots. TEM is like looking through one of the ghetto microscopes you used in grade 9 biology.

Very Cool, with my work I have seen corrosion deposits/scales under SEM but nothing THIS COOL!!!:biggrin:

so awesome.
Is it just me or does it look like it has two eyes and a smile in pictures # 5 and 6

I'm in love with your 'scope. If someone were to have special requests for scans, would you be able to do them? Like if I wanted a couple scans to print and put up in the fish room, etc?

Possibly, yes. If it's simple enough to slip in with my regular work I can do the odd one here and there. If you wanted to do something specialized and I needed to book the machine for a bit just to do that one sample, the machines cost $30 - 80 per hour (plus $30 set-up), depending on the machine (luckily most of the stuff you'd probably want to see would work fine on the cheap machine). Also depends on the sample as well. If it requires a lot of prep time, then we're talking about my time as well.

I'm happy to do them, just depends what it is :wink:

I think those are actually eyes that you see there. The smile is proof evolution has a sense of humor :razz:

So, what is this critter? Other than a really itty-bitty trilobite?

See post a couple back. Easy answer: it depends.

This happens to me pretty much every time I come on the internet. Typically goes like this: Photocatalysts... nanorods... quantum mechanics... 1 hr later... aquarium stufff... 3 hrs later... Batman and the filmography of Adam West...

Shouldn't the raptor have some feathers on it? :)

How small of an organism can you do? I've always wanted to see what a bed of cyano and it's associated fauna looks like under a scope like that. When I looked at my cyano under a microscope, it was as though several species of bacteria, dinos, and worms were using the cyano as a scaffold upon which they lived. It would be cool to get a super detailed image of an assemblage like that.

or small bristle worm. They're suuuuper intricate when you look at them under a microscope.

Too awesome :cool: And you have a SEM and TEM. So jealous!! Our TEM at work was built in the 60s I think (ok probably later than that but cripes is it ever old) one of the EM techs that does the servicing collects parts for us as he comes across old ones that are to be decommissioned. Without him we'd be screwed.

Ha! We finally moth-balled one of our TEMs. I think it might have literally been twice my age (and I'm not that young). My SEM isn't much better :razz:
