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

Appearance

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, while 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.

Behavior

Jellyrays will aimlessly swim around and will flee if approached by the player or a shark-classified fauna. Jellyrays are curious and will swim towards small classified fauna. Despite what their databank says, they are not attracted to sources of light.

Data Bank Entry

Jellyray Scan

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

Trivia

  • The sounds of the Jellyray were created from wolf howls.
  • 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 state 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.
