Auagh

Auagh are a species of egg-laying mammals from the dense temperate forests of the planet Touen. They are large, bulky creatures, with armour plating atop the head and along the back.

The most prominent (potentially only named character of the species) one in the plot (still not a main character) is in Eyoa's squad, called Huoath. Annoyingly vowelly names that you can barely pronounce are the norm for this species.
