Although the Galapagos Islands
are a paradise for bird watchers, they are best known for their
reptile population. The two species of iguana, the land and
the marine iguana, are unique species found nowhere else in
the world. While people sometimes think they look fearsome,
both are vegetarians. The land iguana, which is yellow/brown
in color, lives largely on cactus and has learned to scrape
large thorns off the cactus pads with its feet.
