A test monkey is on the lam after a truck carrying 100 apes to a laboratory crashed. The truck driver, en route to Florida, crashed into a dump truck on Friday outside Danville, Pennsylvania.

Four crab-eating macaques seized the opportunity to escape -- and as of Saturday, one was still at large. . .

. . . Cynomolgus monkeys, as the species is also known, can cost more than $10,000, and were used as test subjects for the development of the [Chinese] COVID-19 vaccine, according to a report.

The intelligent, social primates are also known to utilize stone tools in the wild.
