Figure 3.

Variation in morphological and habitat characteristics among notothenioid species. For each species, black dots indicate means of observed trait values, and gray bars represent standard variation. Body size is measured in cm, buoyancy in per cent, and temperature in °C. Buoyancy values are taken from Near et al. (2012). The phylogenetic tree is identical to the one shown in Fig.1a, excluding species with missing trait data.
