Nidoran♀ is a small, quadrupedal, mammalian Pokémon. It has large, spiny ears; oversized front teeth; red eyes; and a pair of whiskers on each cheek. It is light blue with several darker blue spots. There are two white claws on each of its paws. Its back is covered with small toxic spines, and it has a small forehead horn.
The poisons secreted by the spines and horn are extremely potent, and even a scratch from its horn or a drop of poison from its barbs can be deadly. However, this docile Pokémon only uses its poison when it feels threatened. Nidoran♀ is more sensitive to smell than Nidoran♂. It can use its whiskers to check the wind while either searching for berries or to avoid predators. Nidoran♀ can use its incisor teeth for crushing the berries it forages for. Nidoran♀ lives in open spaces, such as savannas and plains. Nidoran♀ is a female-only species.
Nidoran♀ evolves into Nidorina, which evolves into Nidoqueen.
(For specifics on this Pokémon's evolution in the games, refer to Game data→Evolution data.)
