The mouse and jellyfish are being compared because, the mouse is less likely to decompose when the scientist try to fossilise it, but the jellyfish has the tenticles and when scientst are trying to cover it, it will most likely fall apart/decompose.
Jellyfish are, compared to mollusks, arthropods and vertebrates, very simple organisms. Jellyfish did not evolve a circulatory system, as they can perform gas exchange at their outer surfaces.
there is a lot of contreversy about jellyfish crime as people feel strongly about the jellyfish's well being

Jellyfish
A jellyfish has tentacles which can sting by injecting a toxin. Jellyfish can be extremely dangerous, despite being a very primitive type of organism with no skeletal system.
Blue jellyfish typically have a bluish hue and longer tentacles compared to green jellyfish, which are usually green in color with shorter tentacles. Blue jellyfish are commonly found in open ocean waters, while green jellyfish are often found in coastal areas and estuaries.
Very, they can sting you.

The box-jellyfish is special from all the other jelly-fish because, it doesn't drift but actually moves. All of the other jelly-fish just drift with the current, they are not moving. The box-jellyfish is actually not a jelly-fish. It is just called a jellyfish for its jellyfish appearance not for it truthfully being a jellyfish.
Jellyfish range in size from being extremely small to being very large so their size and the size of their tentacles has an impact on what they are able to consume. Generally speaking, a jellyfish will eat whatever it can catch and keep in its tentacles.
Jellyfish are part of the Phylum Cnidaria, which includes animals with stinging cells. Within Cnidaria, jellyfish belong to the class Scyphozoa, encompassing the true jellyfish species. Further classification into orders, families, and species can vary based on the specific jellyfish being considered.
The Carukia barnesi jellyfish typically live for about 6 to 12 months in the wild. They have a short life span compared to other jellyfish species.
