Genome-wide phylogeny reshapes our understanding of the evolution of deep-sea dragonfishes, bristlemouths, viperfishes, and allies (Stomiiformes) - BMC Ecology and Evolution
Background The evolutionary relationships within Stomiiformes, a diverse order of deep-sea fishes dominating the mesopelagic and bathypelagic zones, remain contentious due to conflicting morphological...

Love how fish will just evolve a truly horrifying number of teeth to crush shelled creatures. Absolute nightmare, my students love seeing this stuff. From Cynthia Worcester's master's thesis (2012; linked below).
