Alpha Peeper Species

The Alpha Peeper is the PDA's hypothesised most recent common ancestor of the Peeper, Eyeye, Reginald, Oculus and Red Eyeye. The data bank entry for this creature can be obtained by scanning a Peeper, a Reginald and an Eyeye.

Theory
It is theorized that the Alpha Peeper species was a small, common prey fish living in shallow waters. Over time the creature developed patches of photosensitive cells on the body, similar to the primitive eyes still retained by some creatures today known as eyespots. Over the period of hundreds of thousands of years these eyespots developed into eyes and the creature diverged into several species, three of which survive today as the Reginald, Peeper and Eyeye, with the Peeper later evolving into the new species, Oculus. Though it is known that one of the two Eyeye types is a subspecies of the other, the PDA is unable to determine whether the Red Eyeye evolved from the common Eyeye, or the common Eyeye evolved from the Red Eyeye.

The Eyeye is unique amongst the descendants of the Alpha Peeper in that unlike the Reginald and Peeper which both have one large eye on either side of the body, it has a single, huge central eye making up almost 90% of the body. The Eyeye is also very primitive compared to its two relatives, with the Peeper being one of the most developed small fish species in behavioural complexity.
