Worksheet 2: Fish Morphology
Fish Morphology, Part 1: Cross-Sectional Body Shape
Instructions: Fill in the table on fish cross-sectional body shape. Cross-Sectional
Body Shape Name Example Characteristics Shipwreck Habitat
Fusiform
(Ex: Yellow-fin tuna)
Streamlined. Fast-swimmer. Often in water-
column.
Water column above
shipwreck.
Compressed
(Ex: Tautog)
Quick speeds for short distances.
Not always moving because
use bursts of speed.
Around and in wreck structure.
Depressed
(Ex: Gulf flounder)
Swim along bottom like a flying bird. These are
bottom-dwellers.
Bottom of shipwreck or nearby sand.
Anguilliform
(Ex: Conger eel)
Not good swimmers.
Ribbon shaped.
Crevices in shipwrecks.
Lesson Plan -- Shipwrecks of NC: Where do the fish live? -- Avery B Paxton
Fish Morphology, Part 2: Caudal Fin Shape
Instructions: Fill in the table on fish caudal fin shape.
Cross-Sectional Body Shape Name Example Characteristics Shipwreck
Habitat
Rounded
(Ex: Queen Angelfish)
Short bursts of speed. High
maneuverability. Lots of drag.
Around and in wreck
structure.
Truncated
(Ex: Yellowedge Grouper)
Short bursts of speed. Good
maneuverability. Not as much
drag as rounded. These are
usually bottom-dwellers.
Bottom of shipwreck.
Forked
(Ex: Sheepshead)
Good speed over longer distances.
Good maneuverability. Less drag than
truncated.
Around and in wreck
structure.
Lunate
(Ex: Blue runner)
High speed over long distances.
Poor maneuverability. Rigid with less surface area and
less drag.
Water column above
shipwreck.

Fish Morphology, Part 3: NC Shipwrecks Instructions: Indicate the morphological characteristics of each fish species. Use your understanding of morphology to decide where each fish would live on a shipwreck.
