  1. Tetradontiformes : The Hawaiian Reef Fish By: Jeremy Shields, Lauren Switzer, Megan Lamrock

  2. Triggerfish (Balistidae) • Body shape • Color patterns • Special spines • State fish of Hawaii

  3. Hawaiian Triggerfish • Lagoon Triggerfish (Rhinecanthusaculeatus) • Reef Triggerfish (Rhinecanthusrectangulus) • Pinktail Triggerfish (Melichthysvidua)

  4. Hawaiian Triggerfish • Black Triggerfish (Melichthysniger) • Lei Triggerfish (Sufflamen bursa) • Bridled Triggerfish (Sufflamenfraenatum)

  5. Hawaiian Triggerfish • Gilded Triggerfish (Xanthichthysauromarginatus) • Crosshatch Triggerfish (Xanthichthysmento) • Bluelined Triggerfish (Xanthichthyscaeruleolineatus) • Finescaled Triggerfish (Balistespolylepis)

  6. Filefish (Monacanthidae) • Body shape • Spines • Skin appearance

  7. Hawaiian Filefish • Scrawled Filefish (Aluterusscriptus) • Unicorn Filefish (Aluterusmonoceros) • Barred Filefish (Cantherhinesdumerilii)

  8. Hawaiian Filefish • Squaretail Filefish (Cantherhinessandwichiensis) • Shy Filefish (Cantherhinesverecundus) • Fantail Filefish (Pervagorspilosoma) • Yellowtail Filefish (Pervagoraspricaudus)

  9. Boxfish (Ostraciidae) • Body shape • Appearance • Ostracitoxin

  10. Hawaiian Boxfish • Spotted Boxfish (Ostracionmeleagris) • Whitley’s Boxfish (Ostracionwhitleyi)

  11. Pufferfish (Tetradontidae) • Body shape • Appearance • Tetraodotoxin • Expandable stomachs

  12. Hawaiian Pufferfish • StripebellyPufferfish (Arothronhispidus) • Spotted Pufferfish (Arothronmeleagris) • Ambon Pufferfish (Canthigasteramboinensis)

  13. Hawaiian Pufferfish • Hawaiian White Spotted Pufferfish (Canthigasterjactator) • Lantern Pufferfish (Canthigasterepilampra) • Maze Pufferfish (Canthigasterrivulata)

  14. Hawaiian Pufferfish • Crown Pufferfish (Canthigastercoronata) • Floral Pufferfish (Torquigenerflorealis) • Randall’s Pufferfish (Torquigenerrandalli)

  15. Habitats of the Hawaiian Tetraodontiformes • Triggerfish • Pelagic to semipalagic • Filefish • Juvenilles • Adults • Varies by species http://hawkebackpacking.com/hawaii_snorkeling.html

  16. Habitats of the Hawaiian Tetraodontiformes • Boxfish • Coral/rocky, shallow reefs • Pufferfish • Reefs • Open Ocean Clark Little

  17. Dietary Specializations of the Hawaiian Tetraodontiformes • Triggerfish • Wide Range • Fused teeth • Blowing water/fin flapping • Filefish • Benthic invertebrates to zooplankton

  18. Dietary Specializations of the Hawaiian Tetraodontiformes • Boxfish • Omnivorous • Pufferfish • Mostly carnivorous • Fused, beak-like teeth • Specialization

  19. Schooling Behaviors • Triggerfish • Usually territorial • Filefish • Solitary to small groups • Boxfish • Territorial • Pufferfish • Solitary to schools

  20. Tetradontiformes Reproduction • Males / Females • Pelagic • External Fertilization • -Broadcast Fertilization • Mating

  21. Lateral Undulation vs. Dorsal & Ventral Fin Propulsion

  22. Tetradontiformes Movement

  23. Tetradontiformes Defense • Thick Plates • Sharpened Spines • Inflation • Poison

  24. Sushi… It’s What’s For Dinner Tetrodotoxin

  25. Pufferfish Inflation: Functional Morphology of Postcranial Structures in Diodonholocanthus (tetraodontiformes) • Inflation Behavior • Structures that Allow Inflation/ Deflation • Exaptations • Epiphenomena • “True” Adaptations

  26. Why the Blow fish BLOW UP !!

  27. How the Blow Fish Blow UP !

  28. How the Blow Fish Blow UP !

  29. Age and growth of Stephanolepishispidusin 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)

  31. Age and growth of Stephanolepishispidusin the Canary Islands area • Discussion (Mancera-Rodriguez and Castro-Hernandez, 2003)

  32. 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
