3. The Hypnotic Dance of the Glowing Jellyfish

Jellyfish are among the most ancient creatures on Earth, and many species possess the ability to glow. The comb jelly, for example, is renowned for its bioluminescent displays created by light-reflecting cilia that scatter light across its body. This glow serves several purposes, including deterring predators and attracting mates. The moon jellyfish, another luminescent species, uses its glow as a defense mechanism, emitting a bright flash to startle predators. These jellyfish inhabit various marine environments, from coastal waters to the open ocean, and their bioluminescence plays a key role in marine ecosystems. This section will explore the diversity of glowing jellyfish, the science behind their light production, and their ecological importance.
