Terra Gravitas

Aerophyta gelatinosa forms vast, translucent ribbons drifting through Terra Gravitas's turbulent lower shear zones. These gelatinous colonies exploit the hyper-dense nitrogen-argon atmosphere for neutral buoyancy, stretching their porous membranes to filter microscopic organic dust from the perpetual haze. Their semi-solid bodies pulse rhythmically, drawing nutrients into a central digestive vacuole while remaining anchored by flexible, root-like tendrils that snag floating debris. Vulnerable to high-altitude scavengers, Drift-Moss colonies often cluster in dense mats near thermal updrafts for protection. They glow with a faint bioluminescent blue when stressed, serving as both warning signal and attractant for symbiotic cleaning fauna. Despite their fragility, they are the planet's primary producers, converting atmospheric particulates into biomass that sustains the entire sub-stratospheric food web below the cloud layer.

坠地行者（Basis claudens）将其自身永久锚定在土格拉维塔斯星球稀少的、漂浮于超稠密氮氩迷雾中的玄武岩露头之上。其巨大的钙化基座与岩石直接融合，以抵御该星球令人窒息的引力和湍急的大气剪切力。这种固着滤食者将迷宫般的多孔革质触须延伸至令人窒息的浓雾中，捕捉悬浮于沉重气流内的微小有机碎屑。 通过摄取这片富含营养的迷雾，该生物代谢缓慢，其内部液体维持着巨大的静水压力以防止坍塌。在罕见的暴风雨期间，行者会完全缩回其叶状体，紧贴基质直至风势平息。尽管无法移动，它却扮演着至关重要的生态基石角色，将混乱漂浮的碎屑转化为稳定的生物质，供偶尔在其裸露脊线上啃食的移动食腐动物所利用。

搏动静脉（Vena pulsus）呈现为半透明的无定形凝胶，漂浮于 Terra Gravitas 超稠密的氮氩大气中。这些中级掠食者虽具浮力却显沉重，依靠内部细胞器产生的微弱静电场使附近毫无防备的猎物瘫痪。其半流体形态使其能挤入大型生物无法涉足的高压岩石裂隙，从而在这颗超级地球的极端重力下节省能量。 一旦接触目标，搏动静脉会释放快速、局部的电击，使小型脊椎动物或硅基生命体麻痹。随后，掠食者将猎物包裹其中，分泌酸性酶溶解组织，并通过多孔膜直接吸收养分。这种高效且低能耗的捕猎策略，使其能在因大气密度与重力过大而导致主动追击成本过高的环境中维持种群生存。
