The anatomy of a Scyphozoan, or “true jellyfish.”
These cnidarians are 95% water; they lack muscles, bones, have a rudimentary nervous system known as a nerve net, and have tissues derived from only two germ layers.

Jellies in an intimate embrace. Some Cnidarians have a unique mating ritual as seen here - others just shoot what they have into the ocean. Broadcast spawning is common among the more sessile marine creatures. Since it is hard to find a mate if everyone is stationary, you release your eggs or sperm into the water and hope for the best.
