P.233 bottom paragraph: "Transitions between life forms: [Investigators] have reviewed how size influences resource acquisition, mobility, ability to sense prey, and life history strategy based on theoretical arguments and cross-species empirical analyses. [They] now use these relations to understand the mechanisms behind the transitions between the seven realms of marine life: molecular life (viruses), osmo-heterotrophic bacteria, unicellular phototrophs, unicellular mixotrophs and heterotrophs, planktonic multicellular heterotrophs with ontogenetic growth, visually foraging poikilotherms, and homeotherms (Figure 1, Table 1). These seven realms correspond to the traditional taxonomic division of life into viruses, bacteria, phytoplankton, uni- and multicellular zooplankton, fish, and marine mammals. [Their] alternative naming reflects the function of the groups and highlights the factors that determine the characteristic sizes where there is a transition between the groups."
