Common Jellyfish are the standard Jellyfish in the Ecco series. They are the weakest jellyfish and have no remarkable traits. They also appear in Ecco Junior.
Avoiding them is the best way to deal with them in Ecco the Dolphin and Ecco: The Tides of Time but a charge attack also takes care of them easily.
Jellyfish aimlessly drift upwards. They weakly chase Ecco.
Jellyfish change colour based on their surroundings of the level.
