[{"role": "system", "content": "Iguana (, ) is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book \"Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena\". Two species are included in the genus \"Iguana\": the green iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean iguana, which is native to the Lesser Antilles and endangered due to habitat destruction. The word \"iguana\" is derived from the original Taino name for the species, \"iwana\". In addition to the two species in the genus \"Iguana\", several other related genera in the same family have common names of the species including the word \"iguana\". Iguanas can range from in length, including their tail. The two species of lizard within the genus \"Iguana\" possess a dewlap, a row of spines running down their backs to their tails, and a tiny \"third eye\" on their heads. This light-sensing organ is known as the parietal eye, visible as a pale scale on the top of the head, and cannot make out details, just brightness. Behind their necks are small scales which resemble spokes, known as tuberculate scales.\n"}, {"role": "user", "content": "i have a few pet iguanas i just got"}, {"role": "assistant", "content": "Wow!
