  1. Fish Morphology& Shipwrecks Prepared by Avery Paxton February 2014

  2. CROSS-SECTIONAL BODY SHAPEFill out Fish Morphology, Part 1

  3. Example 1: Yellow-fin Tuna

  4. Example 1: Yellow-fin Tuna

  5. Example 1: Yellow-fin Tuna Fusiform

  6. Example 1: Yellow-fin Tuna • Streamlined • Fast-swimmer • Often in water column Fusiform

  7. Example 1: Yellow-fin Tuna • Streamlined • Fast-swimmer • Often in water column Fusiform Where would a fish with a fusiform shape live on a shipwreck??

  8. Example 2: Tautog

  9. Example 2: Tautog

  10. Example 1: Tautog Compressed

  11. Example 2: Tautog • Quick speeds for short distances • Not always moving because uses bursts of speed Compressed

  12. Example 2: Tautog • Quick speeds for short distances • Not always moving because uses bursts of speed Compressed Where would a fish with a compressed shape live on a shipwreck??

  13. Example 3: Gulf Flounder

  14. Example 3: Gulf Flounder

  15. Example 3: Gulf Flounder Depressed

  16. Example 3: Gulf Flounder • Swims along bottom like a flying bird • Bottom-dweller Depressed

  17. Example 3: Gulf Flounder • Swims along bottom like a flying bird • Bottom-dweller Depressed Where would a fish with a depressed shape live on a shipwreck??

  18. Example 4: Conger Eel

  19. Example 4: Conger Eel

  20. Example 4: Conger Eel Anguilliform

  21. Example 4: Conger Eel • Not good swimmers • Ribbon shaped Anguilliform

  22. Example 4: Conger Eel • Not good swimmers • Ribbon shaped Anguilliform Where would a fish with an anguilliform shape live on a shipwreck??

  25. CAUDAL FIN SHAPEFill out Fish Morphology, Part 2

  26. Example 1: Angelfish

  27. Example 1: Angelfish

  28. Example 1: Angelfish Rounded

  29. Example 1: Angelfish • Short bursts of speed • High maneuverability • Lots of drag Rounded

  30. Example 1: Angelfish • Short bursts of speed • High maneuverability • Lots of drag Rounded Where would a fish with a rounded caudal fin live on a shipwreck??

  32. Example 2: Yellowedge Grouper

  33. Example 2: Yellowedge Grouper

  34. Example 2: Yellowedge Grouper Truncated

  35. Example 2: Yellowedge Grouper • Short bursts of speed • Good maneuverability • Not as much drag • Bottom-dwellers Truncated

  36. Example 2: Yellowedge Grouper • Short bursts of speed • Good maneuverability • Not as much drag • Bottom-dwellers Truncated Where would a fish with a truncated caudal fin live on a shipwreck??

  38. Example 3: Sheepshead

  39. Example 3: Sheepshead

  40. Example 3: Sheepshead Forked

  41. Example 3: Sheepshead • Good speed over longer distances • Good maneuverability • Not as much drag Forked

  42. Example 3: Sheepshead • Good speed over longer distances • Good maneuverability • Not as much drag Forked Where would a fish with a forked caudal fin live on a shipwreck??

  43. Example 4: Blue Runner

  44. Example 4: Blue Runner

  45. Example 4: Blue Runner Lunate

  46. Example 4: Blue Runner • High speed over long distances • Poor maneuverability • Rigid with less surface area  less drag Lunate
