Fig. 3 in From a pair to a dozen: the piscivorous species of Haplochromis (Cichlidae) from the Lake Edward system

Fig. 3. Plots of principal component analyses of 21 measurements of 12 groups of Haplochromis from the Lake Edward system with a piscivorous morphology: H. sp. 'latifrons' (), H. mentatus Regan, 1925 (), H. sp. 'rex' (), H. sp. 'simba' (▼), H. sp. 'glaucus' (), H. sp. 'aquila' (), H. sp. 'kimondo' (●), H. sp. 'falcatus' (), H. sp. 'curvidens' (), H. sp. 'pardus' (), H. sp. 'quasimodo' (▲), and H. squamipinnis Regan, 1921 (█); holotypes are indicated by large symbols. a. Based on a PCA of the measurements of all specimens, groups were assigned to four clusters (clusters 1–4), which were analysed further separately (b-f).
