New post is about Jellyfish.
Jellyfish have been around for 650 million years. They were here before dinosaurs and sharks! Scientists think there may be 2000 species of jellyfish. They come in all sorts of color: from pale pink or blue to bright orange-red or screaming yellow.
Some of them live in fresh water. All jellyfish sting, but not all jellyfish have poison, that hurts humans. Of the 2000 species of jellyfish only about 70 seriously harm or occasionally kill people.

The Portuguese man-of-war is world-famous for its extremely painful sting. In fact, it is not a true jellyfish, but rather a collection of separate organisms each with a special job to do, working as a unit.
