A captive Lake Titicaca frog becomes a blur at the Denver Zoo as it leaps for prey. In the wild, the frogs likely eat snails, worms and other rock-dwelling soft creatures, said assistant curator Tom Weaver. In captivity, they can be picky eaters but enjoy red wiggler worms, seen here.

A Lake Titicaca frog swims for its supper at the Denver Zoo. These frogs have been given the unflattering nickname "scrotum frog" for their baggy skin folds, which grow more prominent as they get older. The frogs are frequently sited at marketplaces in Lima, Cusco and other Peruvian cities, where they are blended up and sold as part of a drink meant to increase health and virility.
