For each organism below, predict the degree of lateral flexion of axial muscles based on its anatomy and mode of locomotion. To do so, match the appropriate explanation to each organism.
a. Pacific Bluefin Tuna (Thunnus orientalis): Exclusively axial contractions (lateral direction); no appendicular role
b. Red-backed Salamander (Plethodon cinereus) : Minimal axial contractions; appendicular system dominates
c. Montane Shrew (Sorex monticolus) : Minimal axial contractions; appendicular system dominates
d. Humpback Whale (Megaptera novaeangliae) : Prominent axial contractions (dorsoventral direction); some appendicular role
e. Marine Iguana (Amblyrhynchus cristatus): Minimal axial contractions; appendicular system dominates
f. Wild Turkey (Meleagris gallopavo) : Minimal axial contractions; appendicular system dominates
