The hard shell of a monstrous Whorl nearly compromised my air lock. If I hadn't had a small tube of polymer sealant from the astrotrain I would not be recording this now.
These carapaced organisms propel themselves with some sort of gas-propulsion. Despite their similar appearance to the nautili of old, they do not use a bellows-like system for locomotion, but a steady streaming of gas through their curling shell. I wonder if this heavy armor prevents them from attaining higher altitudes, constrained to hover among the land creatures.
Whorls attack using a short ranged, laser-like beam that has a slowing effect. This makes them especially dangerous when accompanied by packs of melee enemies such as Clay men or Sand Crabs. Luckily this attack is clearly telegraphed and easy to dodge with a carefully timed jump.
