Why exact numbers are tricky
A maximum speed measured for one species under one condition should not be presented as the speed of every iguana.
Temperature matters
As ectotherms, iguanas depend on environmental heat for normal muscle performance. A cold animal will not move like a fully warmed one.
Habitat changes movement
Green iguanas combine running with climbing and swimming, while land and rock iguanas rely more heavily on terrestrial movement.
Escape is a toolkit
Running is only one option. Climbing, diving into water, defensive tail use and hiding can all reduce predation risk.
