This horn is super-heated and allows the Ice Worm to melt through ice in order to burrow.

The head is mainly comprised by a single huge plate which tapers into a long, thick horn sticking straight out from the head. The underside is grey in color and has two rows of parapodia used to grip the ice running parallel down the body. The underside of the creature is bare and unprotected, lacking any protective plating. Beneath these plates are another set of triangular plates that stick out horizontally, each with a backwards facing spike.

The Ice Worm has a very long body, the top side of which is completely covered by a thick segmented exoskeleton.
