The Ubeans are a sentient aquatic species. As an aquatic species, the Ubeans are very good swimmers. While their young needed water to survive, once they matured they are able to breathe air. They resembled anthropomorphic sting rays and had blue- or green-colored skin, which was patterned for underwater camouflage. Their mouths are bracketed by cephalic lobes that presumably directed plankton into their mouths. They tended to stroke these during conversation, analogous to the Human habit of stroking facial hair, such as mustaches. Their large, gullet-like throats may have contributed to the sloshing gurgling sounds of a Ubeans voice. In this case, a Ubeans throat may have been filled with water.
All members of the Ubean race had retractable, venom-tipped claws. Similar to the Kalandans, the use of these claws in any form of combat or attack was considered dishonorable and a sign of madness; to do this was to give in to animal instincts unbecoming of a sentient species.
