jumping spider's eyes

[blepharopsis]

Does anyone know of someone studying jumping spider's vision? I'll be happy to donate my confocal data, otherwise it will never see the light of day

Check out Depth Perception from Image Defocus in a Jumping Spider.
Cheers,

Thank you, Chris. I know this publication! You, re right, the authors might be interested in the imaging technique I used; I don't recall seeing many confocal microscope images of jumping spider's eyes out there, so perhaps I can offer something of value for the folks in that business

I think what looks like an optic nerve is actually a trachea - probably nerves are following it in close proximity, that's often a case in inverts. You may see bits and pieces of image-processing neuropil in the two images tho!

Second and 3rd images are just stunning. Others are great too, but the thought that this was sectioned with just agarose and a vibratome... No chemical to de-sclerotize the chitin? And no methacrylate embedding. I may have to move the old 820 and make room for a vibratome. Amazing images.

Thank you, David!

yes, 7% agarose works surprisingly well even when sectioning very thick cuticle - I'll post images of cross-sections through a Dytiscus diving beetle front tarsus soon, they make good case in point.
