Ray Species on 4546B

Different species of ray indigenous to 4546B, each adapted to different environments. The specimens are 99.99% genetically identical to those encountered on the planet today, suggesting that rays in particular have undergone little evolutionary mutation in the past millenium.

Ghostrays, jellyrays, crimson rays and rabbit rays likely all share a common evolutionary ancestor. The 'alpha ray' would have evolved deep in the ocean trenches, quickly growing in line with available food supplies. It would have most resembled the ghostray in size and appearance, with translucent skin for camouflage and forward-mounted eyes for hunting. A fast and fearsome stalker of small creatures in the dark.

While some rays have stayed within the limits of the cave systems where they first evolved, others are relatively more recent adaptions to new environments, likely the results of overpopulation.

All of the rays on 4546B have given up predation in favor of herbivorous scavenging, and use poisonous flesh to protect themselves.
