Fig 4. 3D posture and movement of C. elegans during foraging.

(a) On axis pinhole views from a 30 second long light field image sequence of a wild type C. elegans organism moving within agarose gel. (b) Perspective views showing corresponding reconstructed mid-line skeletons. The total volume occupied by the animal during the sequence, represented by the grey bounding box, is 0.027 mm³. The nose (red) explores a volume of 0.009 mm³.
