An extremely large and dangerous leviathan, roughly 95m long, with a thick plated exoskeleton that burrows through dense ice shelves with minimal resistance.
Plating: The ice worm is covered in a thick exoskeleton with backward facing spikes. The exoskeleton protects the soft upper body of the ice worm as it moves through the ice. The spikes create treads that rapidly shuttle melted water back as it burrows, similar to tire treads. The anterior of the ice worm is covered in a thicker skin that doesn't require plating.
Super-heated Horn: The horn of the ice worm is the thickest part of the creature. The inner chambers of the horn are filled with deposits of raw alkali metals that react violently with water, creating an exothermic chemical reaction. As the ice worm burrows, small microscopic grooves continuously channel water into these chambers allowing it to burrow with ease.
Behaviors: The ice worm is an ambush predator. It relies on sound traveling through the ice to alert it to potential prey. It then lunges through the ice and uses its horn and mandibles to attack. The ice worm can be temporarily distracted through the use of sonic devices.
Assessment: Aggressive and lethal - Avoid
