17. Sexual Reproduction: They also reproduce sexually, with males releasing sperm into the water to fertilize eggs.
18. Planula Larvae: Fertilized eggs develop into free-swimming larvae called planulae.
19. Polyp Stage: Planulae settle on a surface and develop into polyps, which can produce new jellyfish.
20. Ephyra Stage: Polyps release tiny, immature jellyfish called ephyrae, which grow into adult jellyfish.

Unique Adaptations

Moon jellyfish have several adaptations that help them survive in their environment.

21. Bioluminescence: Some moon jellyfish can produce light through bioluminescence.
22. Regeneration: They have the ability to regenerate lost body parts.
23. Buoyancy Control: Moon jellyfish can control their buoyancy by adjusting the amount of water in their bell.
24. Predator Avoidance: Their translucent bodies help them avoid predators by blending into their surroundings.
25. Toxin Production: They produce mild toxins in their tentacles to capture prey and deter predators.

Interaction With Humans

Moon jellyfish have a significant impact on human activities and the environment.

26. Aquarium Displays: They are popular attractions in public aquariums due to their mesmerizing appearance.
27. Research Subjects: Scientists study moon jellyfish to learn more about marine biology and ecology.
