The fact that the appearance of some species of the planet being similar to that of planet Earth species can be explained as a simple case of convergent evolution. Certain species of small fauna can sometimes be seen forming mostly non-interactive shoals. Fauna on Planet 4546B is capable of enduring and adapting to various environments, although previously unable to thrive due to the presence of the Kharaa Bacterium. Ranging from the tiny, cave-dwelling Rockgrub, to the colossal Sea Dragon Leviathan that spews molten minerals from its mouth.

These tendrils prevent it from swimming as fast as its shallow-water cousin, but each can be detached and regrown, enabling it to escape more easily when caught.This article contains unmarked spoilers. The oculus has adapted by splitting its tail fin into five separate tendrils. The caves in which the oculus lives make it hard to escape from fast predators. While the peeper uses its beak to break down tough corals, the oculus likely feeds on the soft fungal growths of the jellyshroom caves and thus has no need of one. Large, complex eyeballs provide this herbivore superior vision in the dark, and an intense phobia of light.

It is possible a small school of peepers was once cut off in the caves, and the oculus species is how they adapted. While the shallows and the cave systems are separated by just a few meters of rock, foodstuffs and threats in each biome are completely different. This specimen shares genetic similarities with the common peeper. The Oculus will flee from the player much slower than its relative, therefore making it easier to catch. It seems to be afraid of light, as any light source directly pointed at it will make it flee. The Oculus is fairly agile and tends to form small shoals patrolling the Jelly Shroom Caves' vicinity while constantly producing faint but audible clicking sounds.

Its body ends with five swaying stalks for a tail, each having multiple purple stripes and resembling tentacles.Īlso, the Oculus does not have a beak, unlike a Peeper. The Oculus has two tube-like organs that extend from its body to the top and the bottom of its head, which resemble backward-facing jets pushing it forward, much like how a Peeper maneuvers in the water. It has two large bioluminescent magenta eyes, with each featuring very detailed irises, and appears to have no visible mouth. The Oculus is a small, turquoise colored fish with purple on its back that looks very similar in appearance to the Peeper, although around twice the size.
