No! I am not dead yet: Salmon edition

Considering that I just ate pink salmon at less than 30 minutes ago, it sickens me to imagine them am an zombie". A salmon life cycle is one of complexity, they are born in fresh water but then swims down stream to the ocean. They spend most their adulthood in the ocean but when they are read to lay eggs they return up stream. Unfortunately, they never return back to the ocean, they began to rot away from the inside out. Their flesh is rotten and there teeth structure is completely changed. The only purpose of the adult salmon at this point is to reproduce. Me personally, I don't think this fits the ideal zombie concept, but it is a form of the walking dead. Technically the fish are alive, but they are dead as well because they can do much and serve little purpose. I compare this state to a person who is brain dead, they are technically alive but not really.
