Method P.229 note beneath figure 6: "Senses versus size. The left axis and bars show senses used for detecting prey grouped according to size and organismal group (see Supplemental Table 4). The right axis and purple lines show the estimated ranges for sensing a prey a factor of 10 shorter than a predator (for details, see sidebar The Dunbrack & Ware Model of Visual Range). For toothed whales (including dolphins), the echolocation ranges were determined from tank and field measurements of individuals of different sizes (blue hexagons) (see Supplemental Table 5), the line is fitted with exponent 17/8 (see Supplemental Table 1). The vertical dashed gray lines are estimates of the limits of chemotaxis strategies."
Comments P.231 2nd paragraph: "Analysis of body size and senses used by marine organisms reveals that the number of possible senses available to a predator increases with size (Figure 6). Large organisms typically combine several senses for foraging. The lower size limit of vision of approximately 1 cm is clearly borne out, this size indeed corresponds to the smallest size of fish and cephalopod larvae. Some large life forms do not use vision to detect prey, most notably the gelatinous zooplankton, even though they are much larger than 1 cm." P.234 top paragraph: "A central theme is that the development of larger size opens up new possibilities for resource acquisition and sensing. Examples include how the battery of available senses increases with size (Figure 6), how the emergence of multicellularity makes it possible to increase the adult:offspring size ratio and thereby increase fitness (see sidebar Life History Optimization of Offspring Size), and how mortality decreases with size."
