The answer to this question is simple: a jellyfish.
Jellyfish are fascinating creatures that belong to the phylum Cnidaria. They are made up of a gelatinous substance called mesoglea that gives them their characteristic squishy texture.
Here are some other interesting facts about jellyfish:
- They have no brain, heart, or bones.
- They are made up of 95% water.
- They can sting with nematocysts, which are specialized cells that contain venom.
- They are found in all the world's oceans.
While jellyfish may seem simple, they are actually quite complex organisms with a unique way of life.
