Fish Morphology& Shipwrecks

Prepared by Avery Paxton

February 2014

slide6

Example 1: Yellow-fin Tuna

  • Streamlined
  • Fast-swimmer
  • Often in water column

Fusiform

slide7

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??

slide12

Example 2: Tautog

  • Quick speeds for short distances
  • Not always moving because uses bursts of speed

Compressed

slide13

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??

example 3 gulf flounder3
Example 3: Gulf Flounder
  • Swims along bottom like a flying bird
  • Bottom-dweller

Depressed

example 3 gulf flounder4
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??

slide24

Example 4: Conger Eel

  • Not good swimmers
  • Ribbon shaped

Anguilliform

slide25

Example 4: Conger Eel

  • Not good swimmers
  • Ribbon shaped

Anguilliform

Where would a fish with an anguilliform

shape live on a shipwreck??

cross sectional body shapes
Cross-Sectional Body Shapes

Fusiform

Compressed

Depressed

Anguilliform

example 1 angelfish3
Example 1: Angelfish
  • Short bursts of speed
  • High maneuverability
  • Lots of drag

Rounded

example 1 angelfish4
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??

example 2 yellowedge grouper3
Example 2: Yellowedge Grouper
  • Short bursts of speed
  • Good maneuverability
  • Not as much drag
  • Bottom-dwellers

Truncated

example 2 yellowedge grouper4
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??

example 3 sheepshead3
Example 3: Sheepshead
  • Good speed over longer distances
  • Good maneuverability
  • Not as much drag

Forked

example 3 sheepshead4
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??

example 4 blue runner3
Example 4: Blue Runner
  • High speed over long distances
  • Poor maneuverability
  • Rigid with less surface area  less drag

Lunate

example 4 blue runner4
Example 4: Blue Runner
  • High speed over long distances
  • Poor maneuverability
  • Rigid with less surface area  less drag

Lunate

Where would a fish with a lunate

caudal fin live on a shipwreck??

caudal fin shapes
Caudal Fin Shapes

Rounded

Truncated

Forked

Lunate

assignment
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
