Figure 3
Proportions of time and behavioural frequencies during 31 one sec intervals around 939 eggs laid of (a) the male being present at the shell, (b) the male showing mouthing behaviour, (c) male “head shake” behaviour, (d) male “head-in” behaviour, (e) female shifting, (f) egg laying (: black bar); note that in 14 of 939 cases a second ( eggs) or a third egg ( eggs) was laid within 15 sec (grey bars, total eggs). (g) Sperm release, (h) female moving half outside the shell. All panels show medians (black dots) and the total range (dotted lines) for eggs.
