Calcoan

The Calcoans are an unnamed species from the Calco Galaxy. According to the Anderans, their planet has no name, and they're considered a primitive and savage species.

Biology
Calcoans are mammalian humanoids with tridactyl hands and clawed didactyl feet. They have large, bulging eyes, porcine snouts and fangs. No visible distinction exists between males and females.

The Calcoans' home planet has an intermittent supply of oxygen. As a result, Calcoans are physically hindered when operating in an environment where oxygen is more abundant, such as Earth.

Culture and society
Calcoans are regarded as primitive and communicate with animalistic noises. However, they evidently have access to technology, since they wear clothes and use serrated boomerangs as weapons. They don't have any knowledge of explosives.

History
Following their defeat against the Humans at the Anderans' Arena game, this species was presumably exterminated by the Anderans.
