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

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

3. Example 1: Yellow-fin Tuna

5. Fusiform

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

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

9. Example 2: Tautog

11. Example 1: Tautog Compressed

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

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

15. Example 3: Gulf Flounder

17. Depressed Example 3: Gulf Flounder

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

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

27. Cross-Sectional Body Shapes Depressed Anguilliform Compressed Fusiform

28. CAUDAL FIN SHAPE Fill out Fish Morphology, Part 2

29. Example 1: Angelfish

31. Rounded Example 1: Angelfish

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

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

35. Example 2: Yellowedge Grouper

37. Truncated Example 2: Yellowedge Grouper

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

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

41. Example 3: Sheepshead

43. Forked Example 3: Sheepshead

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

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

47. Example 4: Blue Runner

49. Lunate Example 4: Blue Runner

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

51. High speed over long distances Poor maneuverability Rigid with less surface area  less drag Lunate Example 4: Blue Runner Where would a fish with a lunate caudal fin live on a shipwreck??

53. Caudal Fin Shapes Forked Lunate Truncated Rounded

54. Assignment Complete part 3 of worksheet – NC Shipwrecks – Given 10 fish that are commonly found on shipwrecks – Classify cross-sectional body shape, caudal fin shape, and where it lives on a shipwreck
