Bonytongues (Osteoglossomorpha) constitute an ancient clade of teleost fishes distributed in freshwater habitats throughout the world. The group includes well-known species such as arowanas, featherbacks, pirarucus, and the weakly electric fishes in the family Mormyridae. Their disjunct distribution, extreme morphologies, and electrosensory capabilities (Notopteridae and Mormyroidea) have attracted interest by many, yet a comprehensive phylogenetic framework for comparative analysis is missing. We provide a phylogenomic analysis of 179 species (out of 260), 28 out of...
