Luminescent green ray

Luminescent green rays were a type of bioluminescent ray that dwelled in the oceans of the planet Pabu. They were green in color with flat, disc-shaped bodies and a thin tail.

During or after 18 BBY, the Force-sensitive Asajj Ventress took the clone Omega out on Pabu's waters in a Pabu skiff in order to test her m-count. After Omega failed to reach out to the life around her using the Force, Ventress demonstrated the ability by reaching out and summoning a school of luminescent green rays, which began circling the skiff. Omega watched the creatures in amazement until Ventress retracted, after which the rays darted away due to the approach of a predatory vrathean, which surfaced with a mouth dripping with glowing green flesh.
