These strange creatures come in two basic types: marine iguanas (Amblyrhynchus cristatus) and land iguanas. In some areas of the islands they are extremely prolific, as shown here. They are unafraid of people, but the smaller individuals will bolt quickly if a galapagos hawk--one of their natural enemies--passes overhead.
