Characteristics
The fishhook barrel cactus typically grows to a diameter of roughly two feet and a height of three to six feet. However, specimens as wide as three feet and tall as ten feet have been recorded. The common name comes from the spines, which are thick and hooked. It has a leathery asparagus green
cortexIn botany, the cortex is the outer layer of the stem or root of a plant, bounded on the outside by the epidermis and on the inside by the endodermis. It is composed mostly of undifferentiated cells, usually large thin-walled parenchyma cells of the ground tissue system. The outer cortical cells...

during the summer months. The fruits are green when unripe, yellow after the flower dries up, and persist atop the cactus long after the flower is gone, sometimes for more than a year.
In adulthood, fishhook barrel cacti generally leans southward, toward the sun, earning it the nickname "compass barrel cactus." One theory about why this happens is, the afternoon sun is so intense it slows the growth on the exposed side, causing the plant to grow unevenly. Older barrel can lean so far they uproot themselves and fall over especially after heavy rains when the soil is loose. Its life cycle is 50-100 years.

, Ferocactus typically grow in areas where water flows irregularly or depressions where water can accmulate for short periods of time. They are most often found growing along washes and arroyos where their seeds have been subjected to scarfication due to water movement, but they oddly also tend to grow along ridges in spots where depressions have formed and can hold water for some period of time.
The "fishhook" spines and the armored web of spines enclosing the cactus body in many species of this genus is an adaptation which allows the plant to move to more favorable locations. This plants seeds germinate in areas where water movement occurs or in areas where standing water accumulates for some period of time, and during flash floods, the hooked spines allow the plants to be caught on water bourne debris and be uprooted and carried to areas where water tends to accumulate. Ferocactus have very shallow root systems and are easily uprooted during flash floods.
The habitat these plants exist in is hot and very arid, and the plants have adapted to exploit water movement to concentrate their biomass in areas where water is likely to be present.
