In case you're wondering what the heck the "lounge lizards" are in the photo on this "Hellos" page, they're marine iguanas found only on the Galapagos Islands. This is NOT a black and white photo! The iguanas have evolved to look exactly as crusty and gray as the basalt on which they live.
So, there we were snorkeling, and all the sudden this huge iguana (like two feet long) climbs down the rocky underwater shelf and starts munching on sea urchins. And we're thinking WTF! because they look like something that should definitely be in the hot, dry air. Then it lurches back onto the rocky shore and spits salt all over its friends, because that's how they keep from getting dehydrated, they desalinate their blood after ingesting all that saltwater. It was mind-blowing!
I love the ones with their arms draped over each other.
