Habitats of the Hawaiian Tetraodontiformes • Triggerfish – Pelagic to semipalagic • Filefish – Juvenilles – Adults • Varies by species http: //hawkebackpacking. com/hawaii_s norkeling. html
Habitats of the Hawaiian Tetraodontiformes • Boxfish – Coral/rocky, shallow reefs Clark Little • Pufferfish – Reefs – Open Ocean
Dietary Specializations of the Hawaiian Tetraodontiformes • Triggerfish – Wide Range – Fused teeth – Blowing water/fin flapping • Filefish – Benthic invertebrates to zooplankton
Dietary Specializations of the Hawaiian Tetraodontiformes • Boxfish – Omnivorous • Pufferfish – Mostly carnivorous – Fused, beak-like teeth • Specialization
Schooling Behaviors • Triggerfish – Usually territorial • Filefish – Solitary to small groups • Boxfish – Territorial • Pufferfish – Solitary to schools
Tetradontiformes Reproduction • • • Males / Females Pelagic External Fertilization -Broadcast Fertilization • Mating
Lateral Undulation vs. Dorsal Propulsion & Ventral Fin
Tetradontiformes Movement
Tetradontiformes Defense • • Thick Plates Sharpened Spines Inflation Poison
Sushi… It’s What’s For Dinner Tetrodotoxin
Pufferfish Inflation: Functional Morphology of Postcranial Structures in Diodon holocanthus (tetraodontiformes) • Inflation Behavior • Structures that Allow Inflation/ Deflation • Exaptations • Epiphenomena • “True” Adaptations

Age and growth of Stephanolepis hispidus in the Canary Islands area • Purpose – Study growth and estimate age of sampled fish • Methods – Length frequency distribution – Count growth rings (Mancera-Rodriguez and Castro-Hernandez, 2003)
Age and growth of Stephanolepis hispidus in the Canary Islands area • Results (Mancera-Rodriguez and Castro-Hernandez, 2003)
Age and growth of Stephanolepis hispidus in the Canary Islands area • Discussion (Mancera-Rodriguez and Castro-Hernandez, 2003)
Do Reefs Drive Diversification in Marine Teleosts? Evidence from the Pufferfishes and Their Allies (Order Tetraodontiformes) • Purpose: – Determine if reef-association has an effect on higher rates of diversification. • Methods: – Taxonomic sampling – DNA extraction and comparisons
