The "prickly pear" is the cactus fruit or fig and is ripe from July- Sept. It grows, protected by the sharp thorns of the cactus plant safe from all animals.

The prickly pear's high water and vitamin content make it a favourite with the local villagers where it grows and has been used by sailors of the sand and sea for generations as a fruit to take on board. A long pole with a wire net attached to its end is used to collect the prickly pear from its sharp house.
