The prickly pear cactus, belonging to the genus Opuntia, is a type of cactus native to the Americas. It is characterized by its flat, paddle-shaped segments called pads, which can be green or bluish-green. The cactus produces vibrant flowers that can be yellow, red, or purple, followed by edible fruits known as tunas. Prickly pear cacti thrive in arid environments and are well-adapted to dry conditions. They have spines and tiny hair-like structures called glochids that can cause skin irritation. This cactus is not only important ecologically but also has culinary uses in various cultures, particularly in Mexican cuisine.
