Obsidian Sea

Orbiting a vibrant orange star, this world is a frigid expanse of a silicate-rich ocean, frozen solid into a dark, glass-like surface. Immense pressures from high gravity have fractured this glassy crust into colossal, slowly drifting plates. Life here must contend with crushing forces, developing incredibly dense and robust forms to survive the freezing temperatures and navigate the treacherous, shifting ice floes.

Shaped by 🍂 food scarcity

A more robust, radially symmetrical organism that now primarily relies on enhanced internal chemosynthesis to supplement its meager diet, scraping less for sustenance.

Why it evolved

With the collapse of its primary food sources, the Gastric Scraper has evolved to maximize its chemosynthetic capabilities, developing larger internal organs for this purpose to survive the low-calorie environment of the Obsidian Sea. This shift allows it to subsist on mineral scrapes and dissolved nutrients more effectively. However, this increased reliance on chemosynthesis comes at the cost of a less developed radula, making it even more vulnerable to predation by the Cryo-Serpent if it cannot maintain its internal energy reserves.
