It has a globular shape, easily reaching diameters of over one meter, with some specimens even described as exceeding two meters. In some cases, due to impacts or pest activity, it may lose its apex, resulting in clustering. In older specimens that have not experienced suitable climatic conditions, globular growth may stagnate, accompanied by abundant proliferation of offsets across its entire surface.

It reproduces almost exclusively by seeds, although its cultivation is particularly simple.

In its juvenile stage, it forms tubercles that gradually merge to form its characteristic ribs in the adult phase.

One of its main features is the presence of powerful segmented spines in a bright yellow color, so dense that it is usually impossible to touch the plant''s skin with a finger without getting pricked. These spines can reach up to 5 cm in length and possess surprising mechanical strength.

They are highly resistant to adverse weather conditions, withstanding everything from extreme sun exposure to temperatures as low as -5°C without apparent damage. Thanks to their thick epidermis, they easily endure hail and even moderate snowfall. They are rarely affected by pests. Their only vulnerable point is the apex, which remains soft and defenseless during growth periods.

It takes up to 10 years to reach adulthood, from which point it blooms annually.
