The marine iguana looks like a dragon when it puffs steam from its nose. Though it looks fearsome, this iguana is very shy. The Galapagos Islands of the Southern Pacific is its home. The marine iguana is the best swimmer among all lizards, and it often enters water to eat seaweed. The feet are slightly webbed, and the tail is shortened. The tail powers the iguana through water, and the feet sometimes serve to steer the animal. However, normally they are folded alongside their body. Some of the lizards that died out in the past lived out their whole lives in water. Some living lizards like the marine iguana divide their lives between land and water. Some lizards enter water occasionally. Even the desert dwelling Gila monster can swim.
