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.

Shaped by 🦟 disease & parasites

This Gulpfish has evolved a robust immune system and a more solitary existence to survive endemic disease.

Why it evolved

Facing heavy disease or parasite loads, selection favors individuals with stronger immune systems. To reduce transmission rates in the dense populations, a tendency towards more solitary behavior and reduced social contact evolves. Faster maturation also increases the chance of reproducing before succumbing to illness, a crucial advantage in the warm, pathogen-rich Tethys Shallows. A trade-off is a slightly smaller adult size due to energy being diverted to immunity rather than growth.
