Consensus cladogram of osteoglossomorph fishes.^11-13 The evolutionary origins of sensory novelties (red), motor novelties (blue), and sensorimotor novelties (violet) are based on most parsimonious reconstructions of trait distribution across extant lineages. Estimated total numbers of extant species in each lineage (N) are shown, based on a combination of valid species counts,¹⁰ and estimated numbers of undescribed species.^1,14-18 Note that ampullary electroreceptors were subsequently lost in one group nested within the Notopteridae.¹¹
