Question

Classification of Octopus ,Jellyfish and Frog​

Answer 1

Because their body is 95% water, which means they are perfectly camouflaged. The body of a jellyfish is divided into three main parts, the umbrella, the oral arms (around the mouth) and the stinging tentacles. They are animalswith radial symmetry.

But often, people will guess that jellyfish are related to cephalopods—octopuses or squids—since they all have tentacles. ... “In an octopus,” she says, “[the tentacle] is made of meat that you can eat; it's very hardy muscle.” In a jellyfish, the tentacles are more like hollow straws.

Jellyfish and sea anemones are both part of the phylum Cnidaria. They are multicellular, diploblastic, radial symmetric organisms with nematocysts. Class Scyphozoa consists of cup animals and jellyfish.
