This is a terrestrial mollusk which inhabits the Lustre Desert.
The leechfoot sepia has 8 arms, much like a common cuttlefish. These arms are, however, spring-like and tube-like. They are able to bounce quickly by means of hydrostatic power, besides effortlessly lifting their head from the ground. The two tentacles are more similar to an average cuttlefish tentacle.
Their skin is covered in wax, which protects them from dehydration and from electricity. The mantle is flattened on the dorsal side and lacks fins. The gills are enclosed within the siphon, working similarly to a waterlogged lung. The cuttlefish's siphon actively pumps in air while avoiding water leakage. The animal can breath underwater and usually sleeps in oases, where it refreshes.
Its digestive trackt has lost most of its function, and it lacks many digestive organs in favor of a large compartment with the sole purpose of storing water. Its beak is even covered with lips.
Its liver has been remodeled into a kind of battery, which can turn raw electricity into size energy for the creature's fat reserves. This size energy may later by repurposed in the animal's metabolism.
Since the leechfoot sepia has lost much of its digestive system, it must derive its energy from another source. Its tentacles, though morphologically similar to those of most cephalopods, are able to leech in electricity. This can be in the form of the more common but less intense bioelectricity, or in the form of the rarer but much more powerful energy of machines. This has led leechfoot sepias to become "pests" to the inhabitants of the Lustre Desert.
This cuttlefish is nocturnal, avoiding intense sunlight. It uses its great camouflage to avoid people and predators.
