Fish Pokemon

“Pokemon can be classified by following criteria: A low reproduction rate (with the offspring being in most cases of its mother’s species), supernatural abilities like extended longevity (in some cases, as seen in the so-called ‘Legendary Pokemon’, it exceeds several thousand years), the ability to control different elements, large-sized bodies, a sudden second and third mutation/maturity stage, some of which are triggered by the radiation of different ores (and a newly-discovered fourth stage, the ‘Mega-Evolution’ which is triggered by ‘Mega Stones’), and near-human/superhuman intellect, even in animals like arthropods. It was generally believed that Pokemon where a whole different act of Creation, or even extraterrestrial life-forms.

In 1850 however, when a female West-Highland Terrier gave birth to a litter of Lillipups, people began to realize that Pokemon did come, in fact, from normal animals. This caused several theories to spring up until in 1976 the young Pokemon Professor Samuel Oak discovered a virus in one of his samples. First, he believed it to be a contamination, but then curiosity got the better of him. He noted a section in the virus’ DNA he found oddly familiar. In a sample of his Charizard’s DNA, he recognized the exact same section of viral DNA. This lead to a breakthrough in Pokemon research, explaining exactly where Pokemon came from: The ‘Pokerus’ Virus affects the reproductive organs, slipping its genetic information into its hosts gametes and changing the offspring to mutate into Pokemon.”

Fish are the first Pokémon that have a spinal collumn. Having evolved from branchiostoma 550 million years ago, fish Pokémon are one of the most successful Pokémon category. They can also survive conditions that would kill other fishes, as most fish Pokémon not only have gills, but a secondary breathing system that allows them to survive on land. Many also have developed the ability to float freely through the air, as their swimming bladder is filled with a light gas mixture. They still require a humid enviroment and will flee into water if threatened.

Notes:
-Tynamo and its family are not fish. Tynamo doesn't even have a skull, but it grows one as it matures. Eelektrik and Eelektross still don't have jaws though.
-Honedge and Doublade are closely related and it is not uncommon to see a swarm of Honedge uncluding Doublades. Doublade always hunts in pairs. Aegislash is related to them, but hunts solitary. In fact, it has a friendship with a flatfish-like Pokémon that protects Aegislash's eggs and is protected by the sword instead.
-Tapu Fini is the fastest fish Pokémon.
-Gyarados usually lives in rivers, lakes and near the coast. Mega Gyarados lives in the high seas and is a much faster swimmer.
-Arctovish swims on its back.


PLEASE NOTE: This is how I see the Pokemon. It is fine to be of different opinion, but please tolerate mine.
