Cnidaria

name, jellyfish are not actually fish.

They are gelatinous invertebrates in the phylum Cnidaria, and they have been around for over 500 million years.

Most are marine, but some do inhabit freshwater.

The word jellyfish is often used to describe many groups of gelatinous and floating animals, including comb jellies and siphonophores.

They are often processed with a mixture of salt and alum, creating a semi-dried product commonly marketed in China, Korea, and Japan.

Sponges are a

phylum of primarily filter feeders that live their adult lives attached to a substrate.

They are simple invertebrates and are the most primitive of the multicellular animals.

Look, they're simply put incredible.

Now, you may have noticed that I said that this rather large one is known as the string jellyfish, and that's because siphonophores are in the phylum Cnidaria, and they are jellyfish or jellies.

Oh, yes.

What?
