Talitrus saltator, the Sand Hopper

Talitrus saltator is a small amphipod that manages exceptional jumps for an animal of its size (about the width of your thumb). Time precludes putting my whole Talitrus saltator project up as yet. It is scanned and put through Optical Character Recognition (OCR) to save re-typing it all. However, it has yet to be proof read (and there are lots of OCR errors)

In the mean time, here are some of the more interesting illustrations of Talitrus and parts of Talitrus. All are copyright Bob Kirby, but may be re-used under the Attribution-NonCommercial-ShareAlike 4.0 International licence Creative Commons Licence
