The cantaloupe, rockmelon (Australia and New Zealand, although cantaloupe is used in some states of Australia), sweet melon, or spanspek (Southern Africa) is a melon that is a variety of the muskmelon species (Cucumis melo) from the family Cucurbitaceae. Cantaloupes range in weight from 0.5 to 5 kilograms (1 to 11 lb). Originally, cantaloupe referred only to the non-netted, orange-fleshed melons of Europe, but today may refer to any orange-fleshed melon of the C. melo species.
