A female drayjin

The drayjin was a large mammal native to the rogue planet Dakala. The Eska hunted drayjin for food and for trophies.

According to the Eska, drayjin meat was "one of life's great pleasures." Commander Charles Tucker III described a drayjin by saying, "It looks like a big, nasty pig. Kind of tastes like one, too."

Drayjin were migratory and females could be very aggressive, especially when they were protecting a nest. Wraith, who were native to Dakala, were known to turn into drayjins in order to hide from the Eska hunters. (ENT: "Rogue Planet")

The stage directions from the first draft script of "Rogue Planet" described the drayjin as "a large, boar-like creature", though the final draft of the teleplay replaced the last word with "creature". The script also identified drayjin meat as steak.
The drayjin was a CGI model built by John Teska at Foundation Imaging, who used the computer files of previously built targs from ENT: "Sleeping Dogs" and manipulated them into the new creature. (Star Trek: The Magazine Volume 3, Issue 7, p. 54) Teska recalled, "It took a half dozen versions to get it right. I went through a walk cycle, a trot cycle, and a canter, trying to figure out exactly what feel the producers were looking for." (Star Trek Monthly issue 106, p. 44)
