The Mysteries of Jellyfish

Jellyfish are among the most fascinating creatures in the underwater world.

Despite their simple structure, they are remarkably successful predators.

Jellyfish or jellies have been in existence for over 650 million years, making them older than both dinosaurs and sharks.

They don't have brains, hearts, or bones.

Instead, they have a network of nerves, known as the 'nerve net' which helps them perceive changes in their environment.

They also use a system of musculature to navigate through water rather than having a digestive system.

Interestingly, their bodies are composed of approximately 95% water.

Yet, some species are known to possess deadly venom.

Their translucent bodies offer a captivating spectacle, often illuminating the depths of the sea, thanks to the bioluminescent proteins present in their body.

The 'immortal' jellyfish, Turritopsis dohrnii, is able to revert its cells back to their earliest form and grow anew, potentially rendering it biologically immortal.

However, these fascinating creatures are vulnerable to changes in their environment and are threatened by the same pollutant that affects most marine life: plastic.

With their intricate life cycle and evolutionary success, jellyfish certainly exemplify nature’s paradoxical blend of fragility and tenacity..
