Jellyfish, like dolphins, evolved from animals that once lived on land and returned to the ocean.
They are cousins of the sea pig, which evolved from the regular pig.

What terrestrial animal did the jellyfish evolve from?

Before they evolved into jellyfish, they were probably shared a common ancestor with anemones.

Because in one stage of their life cycle, the polyp stage, they look just like anemones.

wait, so that's a jellyfish?

Cnidaria evolved from choanochyte cells on marine sponges

And this common ancestor of jellyfish, anemones and coral probably came from a another ancestor that looked like this. As you can see, the further back you go, the less complex the lifeform gets. The planula stage looks like a unicellular organism. I'm sure you can see where I'm going with this.

The choanocyte looks a lot like a choanoflagellate, the protozoan ancestor of all animals suggesting that the resemblence is due to common ancestry and not jellies evolving from sponges.

This guy is probably on the right track. Compare a choanoflagellate to a human sperm cell. The resemblance is striking!
