2. Marine Iguanas
Darwin called them “hideous”, but marine iguanas are fascinating reptiles regardless of their spiky tough-guy looks. They’re the only sea-going lizard on the planet. These cold-blooded creatures seem lazy on land, huddling enmass on dark rocks to bask in the sun. But once they dive in the water, they’re strong and graceful swimmers. The vegetarians survive on algae and seaweed, and can hold their breath underwater for up to half an hour. A special gland between their eyes helps them sneeze out excess salt. They look like little dragons when they snort out this salty mist.
