The Beauty of Jellyfish (with Some Interesting Facts)

Seeing the same jellyfish picking various colors, I couldn’t help asking, “Are they transparent in color?” Let’s learn more about this superb species.

I took the jellyfish photos at Sea Jelly Spectacular in the Ocean Park Hong Kong. The five photos below are showing the same group named freshwater jellyfish, which are small in size and colorless.

Not all jellyfish are colorless. For example, the purple jellyfish (scientific name is Pelagia noctiluca) vary in colors worldwide. The colors could be pink, mauve, golden yellow and tan.

Jellyfish have many different types, living in the ocean worldwide, from the surface to the deep sea.  Jellyfish have other interesting facts that are worthy of our knowing.

Interesting facts of Jellyfish:

1) It is one of the world’s most ancient animals, exist at least for 500 million years or even longer, say 700 million years.
2) Sizes vary from a few millimeters to over two meters.
3) Some types can sting; whereas, others cannot.
4) Box jellyfish have deadly poison that can kill a human in 30 seconds.
5) Lifespan varies typically from a few hours to several months. However, there is an unusual type reported. Turritopsis nutricula, another name is the immortal jellyfish, can revert to the polyp stage after becoming sexually mature. This reverting ability can go on non-stop if there is no interruption to the life cycle and hence, the lifespan of the immortal jellyfish is a mystery. Naturally, Turritopsis nutricula becomes an object of study for it may hold the key to human immortality.

Jellyfish looks simple, with the bell, jelly-like bodies and tentacles. This marine life moves by squeezing water out from beneath its body, and sinking happens when there is no squeezing. Jellyfish in the aquarium look so fascinating that it is the living proof of the beauty of Nature.
