The terrain was all black lava rock/flows. We didn’t even see marine iguanas they blended in so well until we were almost stepping on them. They wouldn’t even move. Look at the mountain of lizards. They iguanas hold their breath, go under water and feed on the vegetation on corals. When they come up they “sneeze” out the salt they ingested.
Here be dragons comes to mind.
I think they should have been on a Game of Thrones episode….
