The only one of the five Xindi sentient species who is not bipedal and existing in a standard Class-M atmosphere, they instead require the marine environment they have evolved within. On the secret Xindi Council world, they take part with the others from a giant warter-filled tank in the room and tend to be pragmatic and slow to change positions. Like the Xindi-Insectoids, they speak in their own language though translators. The females of the species are slightly smaller, on average.
