You," they said, with an exaggerated look at Neya, "are so sleek and gorgeous in that dress. A figure like that? I could never." A pause. "And you," they said looking coyly at Sai, "are so handsome in that suit. The colors make your skin glow."
They paused, looking surprised when the two asked him about the rays... "Oh... hmm. Well, I'm not a scientist or particularly informed on xenobiology however, if you use the Federation Standard translation of these words," Xal said, switching from Cardassian to Federation Standard and letting the UT keep up, "the etymology of the words suggests one is named for its stinging characteristics, and the other is named for its shape. 'Manta,'" they said, making air quotes, "is derived from a Terran language and means blanket." They paused and pointed at the different rays and made gestures toward the outline of their silhouettes.
"Terran languages are generally quite descriptive." Xal smiled and leaned forward, craning their thick Cardassian neck to see the animals in this touchpool better.
