The Abbai are a humanoid race and were members of the League of Non-Aligned Worlds and are a member race of the Interstellar Alliance, which are joined to the Alliance of Nations. They were one of the many races devastated by the Dilgar invasion, particularly the war criminal Jha'dur. A humanoid amphibian, Abbai can be distinguished from other races by their distinctive fish-like ridged crest on the top of their head (which is larger in females than males). They also possess a raised bone structure above the eyes and very pronounced cheekbones. Like Humans, Abbai have five fingered hands, though their feet possess no external digits. Their hairless skin is thicker than that of Humans, and comes in three basic ethnic groups, coloured either pink, brown or red.
