Morlocks

Morlocks are semi-sentient hominid cave dwellers on Wunderland in the Ringworld Universe. They, like humans, descended from a failed attempt by Pak Protectors to colonize Sol system and nearby star systems. Although the Morlocks have poor vision due to having evolved in Wunderland's cave systems, their other senses are well adapted to their environment. They tend to be timid when alone and prefer attacking in number and utilize stealth to drop on their prey from above. This tactic is aided by the Morlocks' inherent agility and strong climbing abilities. Both Kzin and Humans have at times been preyed upon by Morlocks, and both species have also partaken in their flesh out of necessity, though it is consistently described as foul-tasting.
