Non-avian reptiles have ranges of adaptations to make their hearts more efficient than their predecessor chordates.

b) How does heart morphology differ between the four major groups of reptiles?

c) How does an average reptile heart differ from the other members of the reptilomorpha?

d) Part of why the heart of reptiles can remain more “basal” is because of their low metabolic need – why is metabolic need so low?
