It is very unlikely jellyfish are conscious due to how simple their nervous system is. There are sensory nervous functions too, namely photosensitivity and gravity sensitivity. Jellyfish can react to stimuli, but this is not indicative of sentience: single celled organisms can do this too.
Why do jellyfish not have eyes?
Unlike humans, the “eyes” of most jellyfish are not concentrated in a single organ; instead, the ability to see is facilitated by a network of nerves and proteins called opsins. Imagine that you’re wading out into the ocean with a snorkeling mask on your face, the sun beating down on your back.

How do jellyfish die?
Among laboratory samples, all the adult Turritopsis observed regularly undergo this change. And not just once: they can do it over and over again. Thus, the only known way they can die is if they get consumed by another fish or if a disease strikes the jelly.
