Reptilianoid Betrushian

Reptilianoid Betrushians are a sapient species native to the ringed planet Betrushia. They evolved after the extinction of a sapient mammalianoid species.

When Betrushia was destroyed in 2148, about 150 members of this species were saved thanks to the efforts of Bernice Summerfield and a Betrushian named Liso. The surviving Betrushians were relocated to the planet Massatoris and founded a colony.

Biology
These Betrushians are bipedal reptilian creatures with clawed hands and feet, scaly skin, small teeth and prominent crests on their heads. Despite being reptilian, they can grow facial hair and sweat when agitated or nervous. They lick their eyes with their tongues, like geckos. Their reproduction is oviparous and they produce litters.

Culture and society
Their society is divided in two rival nations, the Cutch and the Ismetch, which have been at war for fifteen years prior to the planet's destruction. Their technology includes dirigibles.
