The Galapagos pink land iguana, Conolophus marthae (C. marthae), is native to only one of the Galapagos Islands. Its entire range is currently limited to Wolf Volcano on Isabella Island. The iguana was first discovered on this island in 1986. Genetic studies of the animal began sometime later, and it was identified as a species separate from other iguana populations on the Galapagos in 2009. Its population might have been as high as 100 in 1986, but now there might be as few as 10 of the animals left alive. Other evidence indicates that this species could have diverged from another line of iguanas about 5.7 million years ago. After that, the other line of iguanas diverged into two other species, C. pallidus and C. subcristatus. The testing that revealed that these iguanas are a separate species from the other iguanas present in the Galapagos most likely included

Explanation:
Detailed explanation-1: -Pink iguanas are not just a different colour from other land iguanas; they are a completely separate species. There are only around 200 left, and they are confined to the slopes of Wolf Volcano on Isabela, making them one of the most vulnerable species in Galapagos, as the volcano is still active.
Detailed explanation-2: -Pink Iguanas get their pink color from their blood vessels. Their skin lacks pigment.
Detailed explanation-3: -Potential predators of young Pink Land-Iguanas include feral cats, rats, and hawks.
