Anatomy

Sydians are covered in chitinous plating, with only the face and, in females, the front torso and groin exposed. Located under the porous chitin are glands that secrete a corrosive enzyme. While concentrated in the antennae and tail fuzz, they are found all over the body. This enzyme catalyzes oxidation of (i.e. rusts) most metallic elements. When living tissue is exposed, the enzyme stimulates low-level ion exchange in the nerves, causing a feeling of pleasure. On non-metallic substances or organisms lacking nervous systems, the enzyme sits inert or is absorbed without effect. Sydian secretions have a slight citrus flavor and aroma.
