Nidorina (Nidorina venoma) is a Poison-type Pokémon and the evolved form of female Nidoran. Its evolved form is Nidoqueen.
Unlike its previous evolution, this species is completely sterile.
Nidorina develops a tougher, rougher hide upon evolution. The horn on its head is underdeveloped and so it relies on scratching and biting foes to defend itself. This Pokémon is usually very docile, however, and its poisonous quills will retract when it is in a relaxed state.
Nidorina feed their young by chewing the young's food for them before letting them eat. When a Nidorina's offspring are in danger, she will emit ultrasonic cries to confuse predators.
