First "I think he's dead Jim"

Grimm just keep getting stronger, larger and smarter until they are killed. Oobleck says the Goliaths are hundreds of years old. There is no full grown for Grimm they just keep growing. The problem with the Deathstalker is it's the only exoskeleton we've seen so we don't know the external differences between minor and major. But just judging from size alone I would lean toward major.
