What specific morphological trait leads to the Wahoo being placed in the unique genus Acanthocybium?

Answer

Its elongated, narrow jaws and razor-sharp teeth

The Wahoo is placed in the monotypic genus Acanthocybium largely due to its unique head shape and mouth structure. Unlike the conical teeth and head shapes found in true tunas, the Wahoo has elongated, narrow jaws and razor-sharp teeth. This adaptation allows the fish to slice through schools of prey rather than engulfing them whole.
