How is a jellyfish and a kangaroo different?

Answer 1

There are many differences between jellyfish and kangaroos.

• A kangaroo is a warm-blooded vertebrate, a mammal that lives on the land. A jellyfish is an invertebrate sea creature, a coelenterate which must spend all its time in water in order to survive.
• Kangaroos have a full respiratory system by which they breathe, using lungs, trachea, nose and mouth, etc. jellyfish breathe by absorbing oxygen and releasing carbon dioxide through their outer surface.
• Kangaroos are marsupials, reproducing sexually, and giving birth to live young which then continue their development in the mother's pouch, nourished by mothers' milk. Jellyfish reproduce by releasing sperm and eggs into the water; these attach to a surface where they develop into polyps, and from this point asexual reproduction occurs, with the polyps developing into another form, the ephyra, which eventually become mature jellyfish.
• Kangaroos are grazing animals, feeding primarily on grasses and plant shoots; jellyfish drift, catching their food via their tentacles, or sometimes pursuing prey.
