The cantaloupe is a type of true melon (Cucumis melo) from the family Cucurbitaceae. 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, including the netted muskmelon which is called cantaloupe in North America, rockmelon in Australia and New Zealand, and spanspek in Southern Africa. Cantaloupes range in mass from 0.5 to 5 kilograms (1 to 11 lb).
