Poison Baldur Slug

Aplysia lux, more commonly known as the Poison Baldur Slug, or, more simply, Baldur Slug, is a species of sea hare native to Trans-Rathniri(an) Ocean (catch-all

term used to describe the combined Endless, Lothranis, Phagosian, Kushite, Baldic, Rough, Astyllean, and Svalden Seas; sometimes referred to as the Great Southern Ocean) as well as the Sea of Pearls. Due to the only semblance of a skeleton being soft proteins, the only way to test for the species' age is through testing for their ink.

Anatomy
Aplysia lux, like its relatives, is very large, with the average weight of an adult being ~5.7 kilograms. The Poison Baldur Slug is about bilaterally symmetrical.

Phagomimicry
Although the Poison Baldur Slug bears many similarities to its close relatives, its defining feature is the ink it uses in phagomimicry. This special ink has a composition that is more lethal than most sea hare's inks, it is even toxic to hominids. This ink can be used to kill Termincrawlers, at small doses, can tranquilize larger animals, and at large doses, even kill larger animals. Depending on where in Rathnir the ink is acquired, the ink can be more or less toxic.
