Jellyfish

 

Jellyfish are also known as jellies!  The English term, jellyfish, was first used in 1796,   Even though they are called jellyfish, they are not fish!  Jellyfish lives in the ocean all over the world. Some also live in fresh water.  Some of the jellyfish are deadly, but most of the time they don’t want to harm humans!  But they have been known to sting humans and even cause death. 

 

Jellyfish don’t exactly have brains. Instead they have something called a “nerve net”!  A nerve net is a collection of neurons that act like a brain, by sensing changes in the water and the environment. Jellyfish can also tell if they have passed an animal or if they are facing up or down thanks to their nerve net. 

 

The underside of the dome-shaped or bell-shaped body of the jel-lyfish is the mouth that is surrounded by the tentacles.  They have no blood or nervous system!
