Figure 3.

Percentage of observations in which the different euplantulae of A. diadematus larvae were in contact with a glass plate. (a,b) Plate orientated horizontally and animal standing above (a) or hanging below (b) the plate. (c,d) Plate orientated vertically and animal facing upward (c) or downward (d). For further analyses, data from the fore-, middle and hind legs were pooled. Within each column, different letters indicate significant pairwise differences between groups. Within each position (row), asterisks indicate significant differences between the per cent observations in that at least one of the euplantulae E1p-E2 was in contact with the plate and the per cent observations in that E3 was in contact. E1p-E3: Euplantulae numbered according to figure 1 with E1p being the most proximal and E3 the most distal one. ***: significant differences at p < 0.001; **: significant differences at p < 0.01. Four individuals were recorded and each euplantula was observed five to seven times per individual, leg and situation.
