This unique animal is the only sea-going lizard in the world. Marine iguanas are able to dive to depths of 25 metres and can remain submerged for well over 10 minutes before having to return to land to warm up. They can often been seen basking in the sun on exposed lava to raise their body temperature to around 35.5°C.
