How many fingers does a iguana have?

Answer 1

Iguanodon had three toes on each hind foot and five fingers on its forelimbs, one of which was thumb-like because it opposed the others, like a human thumb. The thumb-like finger had a large, sharp claw that may have been used for self defense.

Answer 2

Five on each hand/foot. However, many Iguanas have missing digits.

Answer 3

Iguanas have 5 toes on each foot, giving them a total of 20 toes.
