Solution:
Jellyfish are actually an Invertebrates (without spinal cord) and not fish.
These free-swimming sea creatures move in the direction of ocean currents and are found in almost all parts of the oceans.
Some of the jellyfish are immobile also and are bound to seabeds.
Mostly the Jellyfish have an umbrella or bell-shaped body and are clearly transparent (some of them can have fascinating colours).
They have an opening inside through which they eat their prey and discard the waste through the same opening.
Their fossils confirm their existence in pre dinosaurs periods also.
