Events

Extinctions

Between Weeks 2 and 3, the Cish Plague wiped out all extant cish except the Snoodcish: the Devilcish, Ghost Cish, Gulper Cish, Greenscale Cish, and Sandcish perished. It also weakened Carpotesta Devoratori and Protodevoratori so much that they succumbed to outcompetition by their descendants, which had better immune systems. With its main hosts gone, the cish plague itself then went extinct.

The Kralptus went extinct due to the loss of the Darwin Desert. The Octocrystal went extinct because it was too large to cope with the permafrost in its environment.

Binucleusdetritivorus Thornworm, Binucleus Crystal Shrub, and Laminato were outcompeted by their more successful descendants. The Crystalsucker went extinct due to the loss of its food source.

Dispersal

Several species spread across narrow bodies of water, while others were transported across the ocean by its currents. Here is a list of species that spread this way and where they ended up:
