Fig. 8From: Three Dimensional Tracking of Exploratory Behavior of Barnacle Cyprids Using StereoscopyPolar combination plot showing the swimming speed (vector length) versus swimming angle (angle between the cyprid and the surface) of cyprids over (a) PEG and (b) TMA surfaces. Note the different scaling of the r-axis (swimming speeds) which is in general much larger on PEGBack to article page
