The word "species" acts as an umbrella term for every creature in the game that isn't a pony, it's very likely that species were the very first type of groups to exist on Pony Town before regiments and scouts spiked in popularity. Shorks and Screes were possibly the first species to exist in the game. Species are unique Pony Town creatures that are mostly created and invented by players, however there are also canon species that are occasionally taken from the My Little Pony Franchise like for example: the changelings.
