Like pond skaters, these villagers in Huzhou, in China's Zhejiang province, carved a path across the thick vegetation on water to pick ripe water chestnuts yesterday.

The triangular spiky water plant is in its harvest season when autumn comes to the middle and lower reaches of the Yangtze River, reported Xinhua.

Despite its name, the water chestnut is not a nut. It is an aquatic vegetable that belongs to the sedge family of Cyperaceae, according to the website HealthBenefits.
