Dissertations, Theses, and Masters Projects

Batrachoidiformes, the toadfishes, are benthic fishes that inhabit nearshore subtidal and intertidal habitats, characterized by their dorsoventrally flattened bodies and large pectoral fins. These fishes lack dispersive larvae, and larval development is retained in nests guarded by their parents. To date, 82 species and 23 genera are accepted as valid. Previous studies recognized a single family, Batrachoididae, with four subfamilies: Batrachoidinae, Porichthyinae, Thalassophryninae, and Halophryninae. Interrelationships among subfamilies, however, are unresolved and interrelationships among species are problematic. Despite being a conspicuous member of the coastal fauna, the internal morphology of most species of Batrachoidiformes is unknown, being intraspecific and ontogenetic …
