Kurage

Kurage (クラゲ) is an enemy from Bravoman. These jellyfish-like creatures appear upon the third, seventh, eleventh, sixteenth, twenty-first, and twenty-fifth stages of the game, and will attack either by swimming directly towards Beraboh Man or waiting until he approaches them then swimming upwards to attack him from below; one hit will kill them, and they are worth 300 points. The version depicted in the image to the left is the vertical one - the horizontal version is rotated 90 degrees.
