The animals left little behind, but some body parts were found over the weekend at a game park near Hoedspruit.
“It seems the victim was poaching in the game park when he was attacked and killed by lions,” Limpopo police spokesman Moatshe Ngoepe said.
“They ate his body, nearly all of it, and just left his head and some remains.”
Police have not yet established the victim’s identity. Lion poaching has been on the rise in Limpopo province in recent years.
The big cats’ body parts are sometimes used in traditional medicine, both within Africa and beyond.
Wildlife charity the Born Free Foundation says lion bones and other body parts are increasingly sought-after in South East Asia, where they are sometimes used as a substitute for tiger bones.
In January 2017, three male lions were found poisoned in Limpopo with their paws and heads cut off.
