Experience is a wonderful thing. It enables you to recognize a mistake when you make it again.

LOL Scarab!

I wonder if they could trace back to the origins of the species like that ;)

The magnification isn't really that large in this particular picture. The Scanning Electron Microscope (SEM) is best used for surfaces and superficial structures like in this picture, as its strength is the 3D effect. You could surely get great pics of spermathecae with an SEM.

The one to show extreme resolutions would be the Transmission Electron Microscope (TEM), which work similar to a normal optical microscope, just instead of light the pictures are generated with electrons.

Basically you can show an entire sperm cell in 3D with an SEM, but the fine (= ultra-)structure of a sperm cell would be best pictured with a TEM, by looking at an ultra-thin slice of the cell and seeing all the little gimmicks and gadgets that make up this little powerhouse :)

Know that sounds like a very interesting toy to have!

I don’t think I’ll ever work, I’ll put anything I can find under it just to see what it looks like! :)

The thing that would keep you from doing exactly this is that for both types of microscopes you need to go through a lengthy, tricky and expensive series of preparations until your object is ready for shooting.

There is one type of SEM which allows certain dry, unprepared objects to be viewed, but last I heard also that had its limitations...
