The durian (IPA: [duɾiɑn]) is the fruit of trees belonging to the genus Durio. There are currently 30 recognised Durio species, all native to south-eastern Asia. At least nine species produce edible fruit.[1] Durio zibethinus is the only species available in the international market, but other species can be found in local markets in their native region. The durian fruit is distinctive for its large size, unique odour, and its formidable thorn-covered husk. Its name comes from the Malay word duri, meaning "thorn".[2] The fruit can grow up to 40 cm long and 30 cm in diameter, and typically weighs one to five kg. The shape of the fruit ranges from oblong to round, the colour of its husk green to brown, and its flesh pale-yellow to red, depending on species. Its hard outer husk is covered with sharp, prickly thorns, and the flesh within emits a strong, distinctive odour. Some regard this odour as fragrant, while the uninitiated often find it overpowering or offensive. The edible portions of the fruit are the custard-like flesh and the seed.  [report anonymous abuse]
