Ecco The Dolphin Wiki

Jellyfish are a plentiful creature in the oceans of the Ecco universe, and a common enemy in multiple environments. They are often found together in large schools which makes them troublesome. Jellyfish have been shown to live in a number of water types.

Jellyfish typically use their tentacles to propel themselves towards the surface and disappear off the screen. Jellyfish are passive enemies, but they deal damage on contact. Jellyfish are not edible and can not be eaten by Ecco. They can be defeated with Ecco's charge attack, the Charge Sonar, or the Death Sonar.
