>>45668145no bro, crawdaunt is something like a "regional evolution". hoenn corpish (not the original corpish, the pokedex says it isnt from hoenn) evolved to crawdaunt to disguise as a sharpedo (its skin becomes blue underwater) and survive in hoenn's primordial sea
also sharpedo is related to garchomp so id say crawdaunt is more related to garchomp than primarina. stars on sea characters are common in tv series, movies and games, but that doesnt mean this crab is related to primarina
