Tethys Shallows

A warm, shallow inland sea under a yellow sun and Earth-like gravity. Tidal mudflats meet brackish lagoons; oxygen is plentiful in the water, scarce in the thick muck.

Brackish Glimmer-Ghast

Evo 6FishEats anythingShallows / Shore

A sluggish, iridescent fish adapted to low-oxygen mudflats, with a mouth capable of both filter-feeding and grasping small prey.

Why it evolved

This hybrid inherits the iridescent scales and streamlined body from the Glimmerfin, but its cutaneous respiration is weakened by the Mudfish's adaptations. The intermediate mouth size allows for a more generalist diet than the pure herbivore Glimmerfin. Due to the distant relatedness and conflicting adaptations, this hybrid is likely sterile and possesses reduced vigour, struggling to thrive in fluctuating oxygen levels.
