The thick-skinned jellyfish is a mutated medusa specimen, supposedly from the Cyanea urtica species. The reason for its mutation is unknown, though the DomZ influence may be the cause. Jade encounters a group of them in the ancient mines on Black Isle and the vorax lair, along with other medusas.
Like their name implies, the usually gelatinous body of these jellies mutated into thick skin. Their color is a repulsive green and fangs stick out like feet underneath them. Because of this, they are quite resistant and take several hits to defeat.
Their name is probably based on the real-life Pelagia noctiluca, a jellyfish that can glow in the dark.
