Ice Worm

The Ice Worm is a huge aggressive fauna species that burrows beneath the surface of the ice. They appear to be ambush predators, drawn towards heat and sound above them.

Ice Worms can be avoided through the use of a Thumper.

Appearance
The Ice Worm has a very long body, the top side of which is completely covered by a thick segmented exoskeleton. Beneath these plates are another set of triangular plates that stick out horizontally, each with a backwards facing spike. The underside of the creature is bare and unprotected, lacking any protective plating. The underside is grey in color and has two rows of small spikes running parallel down the body.

The head is mainly comprised by a single huge plate which tapers into a long, thick horn sticking straight out from the head. This horn is super-heated and allows the Ice Worm to melt through ice in order to burrow. Below the horn the creature's four mouth parts can be seen. Each is long and curved with a solid black exterior and fleshy red interior. The inside of the upper and lower pair are lined with black spines. The tail ends with a pair of long and thin spines.

Design
The Ice Worm's design draws heavily on the real-life bobbit worm. Though far greater in size, the Ice Worm shares the hard parapodia running down the body and an ambush-reliant lifestyle.

The Ice Worm's head bears a striking resemblance to this image of a deep sea tube worm, and was likely based on it.

The tail spines of the Ice Worm are similar to the distinctive cerci seen on the rears of earwigs.
