Behavior
The species is diurnal, spending their days foraging, basking and watching over their territories by day and retreating to the treetops at night. Male iguanas are highly visual, and aggressively defend their territories from rival males. The iguanas will deepen their green coloration to intensify their bands, and bob their heads and intimidate intruders by lunging at them with open mouths. They often expand and flare their dewlaps to increase the size of their profile, following up with violent battles amongst each other.

Famous quotes containing the word behavior:
“Growing up human is uniquely a matter of social relations rather than biology. What we learn from connections within the family takes the place of instincts that program the behavior of animals; which raises the question, how good are these connections?”
—Elizabeth Janeway (b. 1913)
“Reading about ethics is about as likely to improve one’s behavior as reading about sports is to make one into an athlete.”
—Mason Cooley (b. 1927)
“The modern world needs people with a complex identity who are intellectually autonomous and prepared to cope with uncertainty; who are able to tolerate ambiguity and not be driven by fear into a rigid, single-solution approach to problems, who are rational, foresightful and who look for facts; who can draw inferences and can control their behavior in the light of foreseen consequences, who are altruistic and enjoy doing for others, and who understand social forces and trends.”
—Robert Havighurst (20th century)
