Alpha Ray Species
The Alpha Ray is the hypothesised common ancestor of the four living ray species on the planet today; the Jellyray, Rabbit Ray, Ghostray and Crimson Ray. The data bank entry for this creature is obtained after all four living rays have been scanned.
Appearance
The entry for the Alpha Ray states that it would have shared the forward-mounted eyes of the Ghostray and Crimson Ray, as befits a predatory creature. It would also have been similar in size to a Ghostray and likely shared the translucent skin.
Theory
Based on the forward-mounted eyes of the Crimson Ray, the PDA theorises that it, and the other three ray species shared a common, predatory ancestor. Appearance-wise the Alpha Ray species is thought to have been close to the Ghostray. The Ghostray is possibly the first creature that the Alpha Ray species evolved into, the Jellyray also being an old species. But in the case of the Crimson Ray and Rabbit Ray, the PDA suggests that they are more recent species.
