The Ray, alternatively referred to as the Rayfish or blinding rayfish, represented a species of predatory scalefish that were naturally found on both the planet of Naboo and Koboh. This particular scalefish was characterized by a protruding lower jaw and a skeletal physical structure. These creatures employed a deceptive hunting strategy, feigning death to lure unsuspecting prey. Once their target was within striking range, they would unleash a powerful flash of light to disorient them, followed by a single, fatal attack.
On Naboo, these scalefish were commonly observed within the waters surrounding the city of Otoh Gunga in Lake Paonga, and they could also be located in the Abyss, where they became the targets of predation by larger aquatic creatures such as the colo claw fish and opee sea killers that inhabited these waters. Conversely, on Koboh, these scalefish were often spotted in the planet's rock pools and watered ravines. There was an instance where a noble made an attempt to keep a blinding rayfish as a domesticated animal. She made the decision to display the rayfish at a social gathering, which resulted in a senator being temporarily blinded by the rayfish's bioluminescent light emission.
In 9 BBY, Skoova Stev, a Sakavian fisherman, managed to capture a blinding rayfish from a ruined High Republic settlement located in the Stone Spires region. He then placed the rayfish into the fish tank situated in Pyloon's Saloon.
The ray made its initial appearance in the movie Star Wars: Episode I The Phantom Menace. Their identification was first documented in the Star Wars Legends reference material Star Wars: Episode I The Visual Dictionary. Their inclusion into the canon was later verified in the reference book Star Wars: Absolutely Everything You Need to Know.
The Ray, along with fellow scalefish doo, mee, faa, see, laa, and tee, appear to be allusions to the real-world musical scale; namely, ""Do, Re, Me, Fa, So, La, Ti, Do."
