It is related to the Nidoran♂ line, and can produce Eggs that contain either Nidoran♀ or Nidoran♂. However, it is the only one of its line that can breed, as Nidorina and Nidoqueen are part of the Undiscovered Egg Group.
Nidoran♀ is a small, quadruped, rodent-like 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 poison secreted by the spines and horn is 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♀ lives in open spaces, such as savannas and plains. Nidoran♀ is an exclusively female Pokémon, Nidoran♂ being its male counterpart.
A group of Nidoran♀ were seen at Professor Oak's Laboratory in Showdown at the Po-ké Corral. These Nidoran♀ were colored the same way as Shiny Nidoran♀, but they predated their appearance.
Team Rocket attempted to capture a pink Nidoran♀ and its male counterpart during the events of In the Pink, but ended up being chased off by a pinkNidoking.
Nidoran has barbs that secrete a powerful poison. They are thought to have developed as protection for this small-bodied Pokémon. When enraged, it releases a horrible toxin from its horn.
Its highly toxic barbs are thought to have developed as protection for this small-bodied Pokémon. When enraged, it releases a horrible toxin from its horn.

Nidoran were the first Pokémon to feature gender, and even gender differences; however, their differences are much greater than those of most later Pokémon.
Despite the addition of genders to most Pokémon starting in Generation II, the two variations of Nidoran remained separate species, rather than a singular species that splits down different evolution paths based on gender.
An Egg laid by a Nidoran♀ does, however, have a chance of hatching into a Nidoran♂, as well as an Egg laid by a Nidoran♂ with a Ditto has a chance of hatching into a Nidoran♀.
Nidoran♀ is the only Pokémon that loses the ability to breed upon evolution.
Nidoran♀ and its evolution share their category with their male counterparts Nidoran♂ and Nidorino. They are all known as the Poison Pin Pokémon.
Due to the fact that its gender, ♀, is included in its name, checking Nidoran♀'s summary from Generation II onward will display as if it were genderless if it does not have a nickname. If its nickname is anything other than "Nidoran♀", its gender will appear as normal.
Nidoran♀ may be derived from needle. It may also come from cnidocyte, a type of venomous cell responsible for the stings delivered by stinging animals, most notably jellyfish. Alternatively, it may be based on 二 ni (two) or 二度 nido (two times/two degrees) referring to the two distinct evolutionary lines with similar names and traits. Also, the Japanese word ran is translated as orchid in English. Orchids are flowers that can be purple or blue, these being the same colors as the male and female evolutionary forms of Nidoran, respectively. The ♀ is an indication of its female gender.
