The cactus in your image appears to be a species of Mammillaria or a closely related genus. These cacti are known for their cylindrical stems and dense clusters of spines.
The pink or red ring of flowers near the top is typical of Mammillaria, which tend to bloom in a circular arrangement. It looks like a healthy specimen! If you’d like more details, I can help identify the exact species based on closer characteristics.
