Hundred-legs

A hundred-legs is described in The Wheel of Time Companion as "an insect with numerous legs". Not to be confused with a hundred-heads.

Nynaeve thinks of the creature when looking out upon the harbour of Ebou Dar:

Smaller ships still, mastless like the boat she was on, with a high sharp peak at the front and a low flat house at the back, spidered across the water on oars, one pair or two, or sometimes three/One long, narrow boat that must have had twenty to a side looked like a hundred-legs skittering along.

This just the Westlands name for, and literal English translation of, a centipede.
