Trade-off between safety and feeding in the sea anemone Anthopleura aureoradiata

Figures & data

Figure 1 Mean time withdrawn time (± SEM) of the sea anemone Anthopleura aureoradiata either in contact (n = 255) or not in contact (n = 225) with neighbouring sea anemones.

Figure 2 Relationship between log-transformed time withdrawn and neighbour density (number of sea anemones within a 60 mm radius of the focal individual) among 480 individual sea anemones, Anthopleura aureoradiata. Equation of the ordinary least squares regression line is: log time withdrawn = −0.016 neighbour density + 1.52.

Figure 3 Relationship between log time withdrawn and disk diameter among 480 individual sea anemones, Anthopleura aureoradiata. Equation of the ordinary least squares regression line is: log time withdrawn = −0.024 diameter + 1.55.

Figure 4 Mean time withdrawn (± SEM) of the sea anemone Anthopleura aureoradiata from three sites in the Catlins region, New Zealand (n = 160 per site). Sites are ranked in increasing order of exposure to wave action.
