North American rhinoceros iguana (SciiFii)

The North American rhinoceros iguana (Sinacyclura rhinoceros), also known as the mainland rhinoceros iguana, the American rhinoceros iguana, and simply the rhinoceros iguana or the rhino iguana, is a species of iguana that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, swamps, forests, open woodlands, grasslands, shrublands, scrublands, and deserts across mainland North America to help boost biodiversity. As among the largest iguanas of North America, the North American rhinoceros iguana can vary in length from 60 to 136 centimetres (24 to 54 in), and skin colours range from a steely grey to a dark green and even brown. Their name derives from the bony-plated pseudo-horn or outgrowth which resembles the horn of a rhinoceros on the iguana's snout, and they vaguely resemble the endangered Caribbean rhinoceros iguana (Cyclura cornuta), hence their names. Although quick to flee when attacked or threatened, the North American rhinoceros iguanas will aggressively attack by biting and repeatedly striking with their thick tail if cornered. The North American rhinoceros iguana is primarily herbivorous, consuming leaves, flowers, berries, and fruits from different plant species. North American rhinoceros iguanas do appear to be opportunistic carnivores as they are known to prey on smaller lizards, snakes, insects, and, rarely, carrion. The conservation status of the North American rhinoceros iguana is Least Concern due to successful conservation efforts, the North American rhinoceros iguana's wide range and its tolerance to many of the human activities.
