Here are some marine iguana photos. We saw lots of marine iguanas. They weren’t all that active, though we did see some swimming, eating algae (their complete diet), crawling, and fighting. But most of the time, they just laid there soaking up the sun to warm their bodies. We got very close to them and when we got too close and irritated them, they spat salt at us. Apparently, spitting is how they get rid of all the salt that they take in from eating algae which grows on rocks in the ocean. Fortunately for us, they were short-range spitters and not all that accurate. I will add, however, that I didn’t get that close to the guy in the last photo.
