Hypothesis: Allometric scaling of mortality versus adult body size across species is predicted by evolutionary life-history theory to be present (and precise) only if all the species in the data set share the same value for the ‘height’ parameter in their body-size growth curves.

Results: This basic prediction is tested and supported in a large fish data set, with the various species spanning the entire range of marine environments, and having about a 12 × range in growth curve height.

Keywords: allometry, body size, fish, maturity, optimal life history.
