Primordial Ocean

The oldest of the currently recoverable evogames on the r/evogames subreddit, the Primordial Ocean is a pixel evogame that lasted just shy of a day (21 hours) before being dropped.

Opening Post
The rules are the same as the first game:

Take a previously evolved organism, and modify it slightly and within reason (no joke organisms). You may not post two evolutions in a row for one organism, and put the time on your post.

The setting:

The bottom of primordial waters covered with rocks and sand. It is fairly shallow, but land is very far.

Five species exist, from left to right:

GIR: A single-celled planktonic organism capable of photosynthesis. It is very abundant and eaten by NICT and CHENU.

VALS: A simple plant with a single root, eaten by EFA.

NICT: A planktonic polyp that catches GIR in its tentacles.

CHENU: A star-shaped creature that lives on the seafloor, consuming detritus or stray GIR that sink to the bottom.

EFA: A blind organism with rudimentary flippers that consumes VALS and the occasional NICT.

I will add environmental factors once in a while that the organisms will have to respond to.

EFA

In order to better be able to find its food sources, the EFA develops antennae featuring an array of olfactory cells.

EFA antennae develop small hairs allowing for detection of movement in the water current.

GIR

GIR develops barbs to defend itself from NICT and CHENU

VALS evolves a split in its root, allowing it to dig deep and absorb more nutrients.

NICTUS branches off from NICT and has thicker skin on its tentacles to receive less damage from GIR's barbs.

NICT grows a second pair of tentacles to use if the others get damaged 10:42

The NICT specializes its appendages. 2 for walking along the ocean floor and 2 for grabbing GIR.

CHENU

To better crawl around the seafloor, the CHENU has developed two-ended tentacles.
