Can you think of a creature that has been living on earth for millions of years? By now you might be able to think of a few examples but how many of them have been living without a brain?😱

The answer to this question is Jellyfish. Yes, you read it right!!! Not just that, Jellyfish have no, heart, bones or even eyes. They just have a nervous system that allows them to sense their environment.🙄

They are made up of a smooth, bag-like body and tentacles armed with tiny, stinging cells. These incredible creatures use their stinging tentacles to stun or paralyze their prey before gobbling it up.

The jellyfish’s mouth is found in the center of its body. From this small opening, it both eats and discards waste.😳 Nasty stuff, eh?

Jellyfish food consists of fish, shrimp,🦐 crabs, and tiny plants. They digest their food very quickly so that they don’t get weighed down by undigested food in their body.

Jellyfish stings can be painful😰 to humans and, from certain species, they can even be deadly. But, you don’t have to worry, these fishes usually don’t attack humans.👍
