^ Images of Illacme plenipes

Top left, Illacme plenipes, the leggiest animal on the planet—individuals have been documented to possess as many as 750. Live image of the dorsal side of a female with 662 legs.

Top right, Electron micrograph of the ventral side of the animal showing a small glimpse of the paired appendages found on each diplo-segment.

Bottom left, Electron micrograph showing the male genitalic morphology, structures shaded yellow and blue; these are actually highly modified legs, the 9th and 10th pair.

Bottom right, Electron micrograph showing the intricate surface structure found on each segment; centermost is the ozopore, the opening to the repugnatorial gland, which affords the millipede a chemical defense.
