Lagartos (Iguanas) and lizards are common everywhere.
Iguanas, 4 and 5 ft.
Large iguanas are numerous.
Like the iguanas, they (at least the males) are provided with a large, expansible dewlap at the throat, which is brilliantly coloured, and which they display on the slightest provocation.
Chameleons, lizards and iguanas abound, as do frogs and toads.
The iguanas are characterized by the peculiar form of their teeth, these being round at the root and blade-like, with serrated edges towards the tip, resembling in this respect the gigantic extinct reptile Iguanodon.
The prevailing colour of the iguanas is green; and, as the majority of them are arboreal in their habits, such colouring is generally regarded as pro FIG.
Although chiefly arboreal, many of the iguanas take readily to the water; and there is at least one species, Amblyrhynchus cristatus, which leads for the most part an aquatic life.
