Skull cap hunter

Many of the planets infected with the skull caps, have a bounty for the death of these creatures. Bounty hunters have become wealthy seeking out these creatures on infected worlds. Many interstellar environmentalists tried to help save the skull caps from extermination by the military and the bounty hunters. Most of the environmentalists made poor hosts to the skull cap creatures, and the few environmentalists who survived, gave up their cause to save these little smart monsters.
