I took a group of students to a local university a few weeks ago to learn about their Scanning Electron Microscope. We were able to bring objects from home to have imaged, and I decided to bring a shed fang from one of my adult female pallida. I just received the images in the mail today and am amazed at the detail. Very neat to see the modified fang type. Enjoy.
Not very sharp from this angle.

Just for effect, this is the pretty lady from which the fang originated.

Chance,
Those were great "macro" shots of the fang and thats a SWEET red spitter! (that will make Bobby "lust" for it)

Cool stuff... SEM is actually a lot of fun and not a whole lot of prep. Here's some hellbender sperm that I looked at a while back. It's at about 4,000X mag. With the setup that we have 15-20kx mag is very doable.
Very neat Bobby. I unfortunately neglected to include the magnification data when saving the pictures, so I haven't a clue what these are. Not a huge amount, but neat looking nonetheless. So does ASU have a SEM? The one we used was at UCA.

Yup, we have SEM facilities, as well as TEM facilities. We actually have quite an active herp-histo lab and do everything from paraffin embedded LM, epoxy embedded LM, SEM, and TEM. Check out the link below to one of my favorite TEM images... The image was taken by my major professor and shows the bi-flagellated sperm of a Siren. You can even see the 9:2 arrangement of the microtubules in the flagella.
Oh goody! What I've always wanted to see!
The arrangement of the microtubules in the flagella!
whaa?
LOL!
Randal
LOL the microtubules are responsible for the motility of the flagella...i.e. makes the spermatozoa move or "swim". In the picture u can see them at the distal (end) portion of each flagellum (the 2 string like structures pending from the central body) as cirle-in-circle structures, kinda like a chariot wheel. The 9:2 arrangement means that there are 9 tubules on the outside and 2 on the inside so clearly identifiable on the microphotograph.
Cheers
Very nice. I've got some old fangs here I've wanted to micro CT for a while, but have just never gotten around to it. Someday I will...
