Animal Trivia : Some jellyfish are Immortal

One species of jellyfish called Turritopsis nutricula, is also known as the “immortal jellyfish”.
The jelly reportedly can play its lifecycle in reverse, transforming from an adult medusa back to an immature polyp.

<Jellyfish Facts>

Jellyfish are made up of water (95%) and protein (5%).

Jellyfish and comb jellies are ancient animals, having roamed the seas for at least 500 million years even before dinosaurs.

Jellyfish don't have brains, but instead, they have nerve nets which sense changes in the environment and coordinate the animal's responses.

Most jellies size are in a range from less than half an inch (1 cm) wide to about 16 inches (40 cm), though the smallest are just one millimeter wide.

The largest jellies are the Lion’s Mane Jellyfish, which can be almost 6 feet wide (1.8 m) with tentacles over 49 feet (15 m) long.
A process called strobilation takes place as shown in video.
