The green iguana (Iguana iguana) is a large, arboreal
lizard from Central and South America. They are typically
about 2 metres in length from head to tail and can weigh
up to 5 kg. It is possible to determine the sex of a green
iguana by examining the underside of the hind legs. Males
have highly developed pores in this area that secrete
scent, and are often covered in a waxy substance. Iguanas
have an unusual behaviour when threatened- they bite onto
the threatening creature and do not let go until forced
to, or the threat is removed.
