The bluefin driftfish or scissortail, "Psenes pellucidus", is a driftfish of the genus "Psenes", found pelagically in all the world's oceans, at depths down to 1,000 m. Its length is up to 80 cm.

The bluefin driftfish has a soft and flabby almost transparent body, covered in small easily-dislodged scales. The lower jaw contains a distinctive series of large teeth and the fish feeds on zooplankton and small pelagic fishes. It is an oceanic species associated with jellyfish and floating weed patches.

Adult body colour is a dark brown to deep purple, with dark blue eyes. Young are translucent with brown spots, and the first dorsal fin is dark.
