Abyssal Vent Strider (Evo 9)

A planet orbiting a K-type orange dwarf star, significantly cooler than Earth. Its atmosphere is rich in nitrogen and carbon dioxide, with a lower oxygen content, leading to a denser, greenhouse-warmed atmosphere despite the cooler star. Liquid water exists primarily in subsurface oceans kept liquid by geothermal activity, with only small, ephemeral surface lakes and rivers in equatorial regions. Dominant habitat is subterranean, within vast cave systems and ocean trenches.

Shaped by 🏞️ new frontier

A larger, more elongated predator adapted to stalk the soft, silty floors of deep cave systems away from the direct vent activity.

Size: 220 cm
Diet: carnivore
Habitat: deep cave systems and hydrothermal vent peripheries
Moves by: walking on soft sediment, with limited swimming capability

Why it evolved

The opening of new deep cave floor habitats, away from the direct heat of vents, favors diversification. This descendant develops elongated limbs for navigating the soft sediment, along with enhanced chemoreception to detect prey like the Geothermal Pneume in the low-light, nitrogen-rich environment. The trade-off is reduced metabolic efficiency compared to vent-specialized ancestors, and vulnerability to crushing pressures if it ventures too deep.
