A phylogenetic supertree of the hammerhead sharks (Carcharhiniformes, Sphyrnidae). Zoological Studies 46(1): 6-11. In this study, 5 hammerhead shark phylogenies (based on morphological, isozyme, and mtDNA sequence data) were combined to generate a complete, well-resolved composite phylogeny for the Sphyrnidae using matrix representation with parsimony. The resulting supertree contains all 8 known sphyrnid species and represents the best estimate of the combined relationships presented in the original 5 source trees. This supertree will provide a useful framework for further phylogenetic comparative studies of sphyrnid evolution, ecology, and biogeography.
