What are the microscopic defensive structures on cactus fruit called?

Answer

Glochids

The text explicitly names the primary immediate danger associated with consuming prickly pear fruit or nopal pads as the glochids. These are described not as large, visible spines, but as clusters of tiny, hair-like barbs that are prone to easy detachment upon minimal contact, often remaining overlooked even after initial cleaning attempts.
