Here are a few photos of the uber-interesting marine iguana! It has evolved to swim and eat seaweed to survive, the only iguana in the world that does either. They also sneeze out salty snot once on land, to get rid of the extra salt they ingest by eating seaweed… We’ve been to a few beaches on Santa Cruz island to watch and watch. It’s amazing how lumpy and slow they look on land, and how graceful they appear in the water. If you haven’t clicked on any of the Instagram photos (and videos) on the sidebar, you really should. Sheena has some excellent videos up there.
