This article is about the Jellyray. You may be looking for the Rabbit Ray, Ghostray or the Crimson Ray.

The Jellyray is a passive fauna species that lives primarily in the Mushroom Forest and Deep Grand Reef.


The Jellyray possesses a translucent, constantly glowing body. It has a long, thin tail and eight, smaller undulating tentacles protruding from each side of its body. The main body glows a violet hue, with bright pink patterns on its back, the rest of the creature glows a light blue colour.

The Jellyray has six circles of various sizes on each side of its torso. These circles could possibly be its eyes, however, it is unknown what their purpose is.


Jellyrays aimlessly glide around, dragging their tentacles behind them when doing so and emitting high pitched cries.

They are curious about light, and can usually be seen investigating any nearby light sources, The curious behaviour fades away after inspecting the light source.

Data Bank Entry


This species has adapted to low-light environments with a translucent, luminescent body.

1. Luminescent Body:
This adaptation may help to light up the surrounding area for foraging, ward away predators, and identify the organism to others of its kind.

2. Light-Sensitivity:
Smaller creatures have been seen swimming in the jellyray's wake to take advantage of the light source for their own ends, and the ray itself will approach light sources, perhaps mistaking them for others of its own species.

Assessment: Inedible



  • The sounds of the Jellyray were created from wolf howls.[1]
  • The Jellyray is a relatively close relative of the Ghostray which is very closely related to the Crimson Ray. These three are also more distantly related to the Rabbit Ray. This is confirmed by the PDA datalogs, which states that they all share a common ancestor.
    • The data bank entry also suggests that Crimson Rays and Ghostrays had a predatory ancestor.
    • Jellyrays possess highly poisonous flesh and as such, they have few natural predators - a trait shared with the other ray-species and probably developed by their common ancestor.
  • Jellyrays are bottom-dwellers, preferring to glide over the seabed. This suggests they're detritivores - surviving from organic waste that settles down on the seabed. This is further supported by the databank entry of the Spadefish.
