Do jellyfish think

Answer 1

Depends on how you define consciousness. If you define it as awareness of one's own existence then no, they do not, because you need a brain to produce such thoughts. However, they can successfully survive based on cellular memory.

Answer 2

Maybe Like all animals, jellyfish spend time resting, but they don't "sleep" like we do. Some species will spend long periods just sitting on the bottom, or hanging in the water column, waiting for something to happen.

Jellyfish do not sleep but they do take rest periods. Australian researchers found that jellyfish will spend long periods of time resting on the bottom of the ocean floor.

Answer 3

All jellyfish, as well as all other cnidarians - the phylum they belong to, have special cells known as cnidocytes, which contain nematocysts. Nematocysts are microscopic, barbed, thread-like structures which are coiled up inside of the cnidocyte and are sitting on a pool of toxins. The cnidocyte has a trigger attached to it and when you touch the jellyfish they fire these harpoon-like stinging threads into your skin, which, in turn, inject the toxin into you. This is how a jellyfish (as well as coral, sea anemones and Portuguese Man of War), defend themselves.
