Raydon

The raydon is a reptilian creature native to the planet Dora.

Biology
Raydons were eight-foot brown lizards that were plant-eaters. Despite being herbivores raydons had big sharp teeth and would attack when threatened.

The human colonists on Dora made it a point to stop their vehicles in the presence of a herd so as to avoid possibly startling them, only moving until the herd went on its way.
