Lion [SEP] Man-eating
Lions do not usually hunt humans but some (usually males) seem to seek them out. One well-publicised case is the Tsavo maneaters; in 1898, 28 officially recorded railway workers building the Kenya-Uganda Railway were taken by lions over nine months during the construction of a bridge in Kenya. The hunter who killed the lions wrote a book detailing the animals' predatory behaviour; they were larger than normal and lacked manes, and one seemed to suffer from tooth decay. The infirmity theory, including tooth decay, is not favoured by all researchers; an analysis of teeth and jaws of man-eating lions in museum collections suggests that while tooth decay may explain some incidents, prey depletion in human-dominated areas is a more likely cause of lion predation on humans.
