Look deep into a jumping spider’s spotted, moving eyes

In previous posts I’ve shown the unusual spotted pattern inside some Habronattus males’ eyes, and you’ve seen the moving eyes of the transparent yellow amycine jumping spider. Here I’ll combine the two to show you what the spotted patterns look like in a living male Habronattus aztecanus.

To remind you, here is what the eye pattern looks like:HaztecanusEyeIMGP8780closeup

And now to the video.  I managed to get this video’d just yesterday, by pulling a piece of transparent plastic film over a live male to hold him down so that I could get him under the microscope. Enjoy!

Oz’s Glass Spider

Last week my old video on moving spider eyes went fungal (that’s a bit slower than viral), following its linking from Gwen Pearson’s Wired column, then io9, then reddit. In honour of its recent fame, I repost the story that introduced the video, from my now-lost blog at the Beaty Museum.

In L. Frank Baum’s Land of Oz, there lived a glass cat who was rather proud of itself. Being glass, it was transparent. It would say “I have the handsomest brains in the world. They’re pink, and you can see ’em work.”

In Canandé we found the most remarkably transparent jumping spider I’ve ever seen. It’s an amycine, but I don’t know exactly which one. Here is a close-up of the male’s body. At the back of the carapace, you can see the muscle bands for each of the legs, separated by yellow, which may be the blood pooling.

You can also see the eyes quite clearly. The black patches on the head are the smaller side eyes, but the main eyes extend like cones backward from the face. In the living spider you can see these cones move as the spider is looking in one direction or the other.

Quite remarkable. “I have black eyes, and you can see ’em work.”
