Figure 3.

Size values through time of all larvae across experimental treatments. (a) Larval sizes in all treatment cups where black dots represent non-competent larvae (lacking a visible eyespot) and red dots represent competent larvae. (b) Average sizes with error bars ± SE for larval treatment cups. Red dots represent samples where over 25% or larvae sampled were visibly competent. In both plots, the horizontal line at 260 µm represents the size at which we considered larvae late-stage veligers.
