A towering, multi-limbed alien predator with green iridescent skin and a translucent head, in a dark swamp.

Ultra-detailed concept art of a towering alien predator called the Thryx, 3 meters tall, segmented torso that can unfold into multiple configurations, oily black-green iridescent skin with a rotting metal sheen, blank translucent cartilage face with faint vascular patterns, face splitting into four hinged plates revealing a lamprey-like proboscis with black hooked denticles, eight multi-jointed limbs with asymmetric claws that can reshape into tools, limbs in an alternating spider-like and serpentine posture, body coated in hair-thin sensory filaments waving in the air, standing in a dark methane swamp under permanent twilight, atmosphere heavy and oppressive, cinematic lighting, hyper-realistic texture detail, horror science fiction style.
