A "normal" ball python is just the standard patterning. Think of it like if you came across one in the wild, that's what it'd look like. This species has such variability in colors and patterns in the pet trade. "Morphs" are bred in order to change its colors and patterning and develop what some people see as a more valuable, prettier snake. Morphs can range in price from just above a normal's price all the way up into the thousands.
