Green iguanas have strong jaws with razor-sharp teeth and powerfull tails.
Fast Facts
- Description
- Arboreal; earthy green lizard with transverse bands on the body
and tail; short, powerful limbs; sharp claws; long, strong tail; large
flap of skin (dewlap) that hangs from throat and helps to regulate
temperature; prominent crest of soft spines along the middle of the neck
and back, beginning at base of the skull
Male: Males typically have brighter overall coloration than females

Female: Slightly smaller than males

- 4.5-6.75 kg (10-15 lb.)
- Diet
- Omnivorous as young but adults are almost exclusively
herbivores; fruits, flowers, leaves; insects and snails
opportunistically; young iguanas eat more insects and shift to 95%
vegetation as they age
- Incubation
- 60-85 days
Clutch Size: 10-50 eggs
- Sexual Maturity
- 2 years; males sometimes longer (need longer period of growth in order to be large enough to compete for females)
- Life Span
- 15 years
- Range
- No data
- Habitat
- Tree dweller in tropics; trees/bushes close to water in tropical rainforests; prefers temperatures in the upper 90s (Farenheit)

Fun Facts
- Iguanas are able to hold their breath for up to 30 minutes.
- They will often jump from tree to water using their powerful
tail for swimming to escape. They are also able to leap down 40-50 feet
without injury.
- To attract a mate, mature males may turn orange during breeding season.
- Iguanas store large amounts of fat in their lower jaw and neck
area in order to survive times of famine. The pouch at the base of their
neck is called a dewlap, and is used in display.
- Their tail has weakened vertebrae so the iguana can break free
and escape if caught by the tail. Iguanas are also able to whip their
tail in defense, leaving behind a stinging welt or worse.
Ecology and Conservation
Iguana meat is a valuable source of protein; theoretically, farming
iguanas could yield more meat per acre than cattle, while requiring only
70% of what a chicken consumes. With the loss of habitat due to
deforestation, iguana farming research is on the rise.
Iguana eggs are also considered a delicacy in the tropics, coining the term "chicken of the tree."
Although not listed as endangered or threatened, populations are
under pressure from both habitat destruction and their popularity in the
pet trade.
