  • The marine iguana is one of the few strictly vegetarian lizards in the world. It mainly eats seaweed.
  • The saw-like ridge of spines on the iguana’s back not only gives a sinister appearance but also helps regulate its body temperature as the iguana basks in the sun.
  • Marine iguanas sneeze. They do this because when eating, they swallow saltwater, and once back on land, they have to get rid of the salt. As they sneeze, the saltwater comes out.
  • An iguana can grow another tail if it is cut off.
  • Iguanas are able to stop their heart from beating for as long as one minute.
