Prompt

Concept art of a grotesque alien organism. The body is a giant, floating brain with complex folds and translucent skin. Underneath the cerebral mass, numerous muscular tentacles with small suction cups hang down like a jellyfish. In the center of the structure is a terrifying maw filled with multiple concentric circles of sharp, predatory teeth. The creature is hovering in a futuristic laboratory tank filled with green fluid, macro photography, detailed texture, sci-fi horror.
