Figure 8 in The phylogeny and taxonomy of Hippopotamidae (Mammalia: Artiodactyla): a review based on morphology and cladistic analysis
Figure 8. An example of convergence in the Hippopotamidae: orbit elevation. From bottom to top, right lateral views of the neuro-crania: KNM-WT 19633, Hippopotamus gorgops from the Nachukui Formation, West Turkana, Kenya, housed at the NMK, Nairobi; 36824, Hexaprotodon palaeindicus from the Narbada beds, Central India, housed at the NHM, London; KNM-ER 798, holotype of Hex. karumensis, from the Koobi Fora Formation, East Turkana, Kenya, housed at the NMK, Nairobi. The elevated orbit is related to an aquatic way of life (Mazin & Buffrénil, 2001), indicating a preferential position at the air/water interface. These three species belong to three different lineages and evolved from forms with much lower orbits.

Figure 1 in The phylogeny and taxonomy of Hippopotamidae (Mammalia: Artiodactyla): a review based on morphology and cladistic analysis
Figure 1. Synthesis of recent phylogenies (Harrison, 1997; Weston, 2000) for the family Hippopotamidae. The genus Hexaprotodon is shown to be paraphyletic, and Hippopotamus being related to the derived species Hex. protamphibius. The important position of Hex. harvardi and the early divergence of the Hex. liberiensis lineage can be also noted.

Fig. 31 in Morphology and Taxonomy of Isopoda Anthuroidea (Crustacea) from Sulawesi with description of six new species
Fig. 31. Colanthura gerungi sp. nov., SEM-images of a male specimen. Cephalothorax in ventral and lateral view. The maxillipeds are flanked laterally by mandibles which are fused to the cephalothorax. This explains why mandibles are usually missing among dissected mouthparts of this genus. The part distally in between maxillipeds is the hypopharynx, which envelopes the maxillae and distal parts of the mandibles. Note the bulging lenses of lateral eyes.
