The majority of the cactus in the Sonoran Desert are stunning to look at, but one variety can be dangerous to people if they come into contact with it.
It is the chain fruit cholla, sometimes referred to as the jumping cholla due its “jumping onto the skin or clothing of a bystander from a parent plant or the ground.
Of course, the barbed cactus spines don’t actually jump. But when individuals come too close, they quickly separate from the main plant and hook tenaciously, sometimes painfully.
“According to John Wiens of the botany section at the Arizona-Sonora Desert Museum west of Tucson, I don’t believe there is a person who enjoys being outside who hasn’t experienced that experience at least a few times.
Can you jump at cacti?
The leaping cholla, also known as the teddy bear cactus, gets its common name because if you come too close, a section will break off and fly towards your body. A flying cactus, indeed. See the jumping cholla in action by watching the video up top! Avoid being a victim!
As to why cacti jump,
The leaping cholla, or Cylindropuntia fulgida, is a perennial shrub that is a member of the cactus family. It is indigenous to the Sonoran Desert in North America, which stretches from Arizona in the United States to Baja California in Mexico. They can be found in Australia, South Africa, and the Pacific Islands in addition to their native area.
These cacti range in size from smaller trees that are almost 10 feet tall to lower branching cacti. Due to the deserts’ severe water shortage, the leaves have been reduced to spines. Additionally, they open in the late afternoon and have tiny flowers that are typically pink or magenta.
The surface of these cacti is covered in barbed spines, or glochidia, which can be uncomfortable to touch and are difficult to remove when attached to human or animal skin. The name “jumping cholla” comes from these spines, which are white or golden in color and quickly detach when the plant comes into touch with someone.
Does the Jumping Cactus Actually Jump?
You must be curious in the jumping cholla after hearing rumors or misconceptions about it “The cactus that jumps actually jumps, right? The answer is no, and this ostensible fact is in no way true.
When people imagined that the thorns pounced on their bodies and stung them, the tale was born. But over time, the misunderstanding was dispelled. It was found that the passerby was being reproduced vegetatively via the stalk and thorns.
Jumping cacti have a lovely appearance and give off an off-white shimmer, but after being stung once, you will know to stay away from them. The plant’s stings can be quite painful and can result in itching, inflammation, and even deep cuts.

The primary explanation for these plants’ alleged “Jump is the term for the loosely connected stems and thorns that affix to onlookers or passing animals as they approach the cacti. Even while you won’t feel the thorns cling to your body, they can be quite painful when they make contact with your skin.
Surprisingly, the cactus’s loose joints aid in both self-defense and the growth of new cactus plants. This occurs when the adult plant’s dead stalks fall to the ground around it, forming roots that sink far into the sand in quest of a water supply. It becomes one of the most dreadful and hazardous cactus accessible in the world when additional new cacti sprout from the area around the original plant, establishing a cacti colony.
Cactus needles do they jump?
The chain-fruit, also known as the jumping cholla, is known for having the ability to “jump from the ground or from a parent cactus to a person’s clothing or skin.” The “cactus that shoots needles” does not truly jump or shoot needles, so don’t panic.
It just rapidly and easily separates from the parent plant and latches obstinately onto (and occasionally into) anyone who approaches too closely or happens to be in the vicinity when a strong breeze blows. It is likely because of its ease of attachment that people refer to it as “jumping” or “shooting needles.”
To survive, the cholla detaches readily. A joint roots when it separates and subsequently drops to the ground. The plant thus grows rapidly. The spines root when they fall to the ground, establishing a new location for the cactus, if a person or animal is able to remove them after the joint has traveled on fur or skin.
Because of the mature plants’ close-growing barbed spines and lengthy “chains of fruit sans spines that hang from the trunk,” it is frequently simple for the chain-fruit cholla to catch individuals passing by. These chains can get rather long in certain places.
People can easily come into contact with the thorny spines that appear to nearly jump at them when they pause to inspect the fruit. The jumping cholla’s spines are also rather springy or bouncy, which increases their capacity to ride along with you.
Jumping chollas are among the prettiest and largest in the desert, despite their repulsive propensity to stick to people. With lengthy chains attached, they can reach heights of up to 15 feet, and from late May through June, they bloom with exquisite pink and lavender flowers.
Is there a moving cactus here?
To emphasize the beauty, diversity, and extraordinary qualities of our common planet Earth, One Earth’s “Creature of the Week series” features a relatively obscure and unique species every Wednesday.
If you came across a creeping monster in the desert, you could have thought someone had used a machete to cut through a field of cacti. No, instead of seeming like a thorny snakes’ nest, this unique variety of cactus rests horizontally on the ground in colonies with only its tip pointed upward toward the sun. The crawling devil may also move across the desert on its belly, somewhat like snakes.
The creeping devil, also known by its scientific name Stenocereus eruca, is the only known moving cactus in the world and is an endemic to the state of Baja California Sur in northwest Mexico. The plant’s prostrate position aids in both its ability to move across the desert for extended periods of time as well as its ability to survive in solitude. It accomplishes this by spreading out horizontally from its stem while also eliminating its tail. It develops new roots as it gently creeps across the desert floor in order to attach itself and to take in water and nutrients. The plant receives nutrients back through the roots as a result of its back end disintegrating and assimilating with the soil. The creeping demon must, in a sense, kill off a portion of itself in order to travel, but this dead portion then feeds the newly formed living portion.
The climate where a creeping devil grows determines the pace of growth and the speed at which it moves. It moves at a speed of two feet each year in its natural region, where the climate is humid and marine.
This cactus can reproduce sexually, but due to its isolation and the dearth of pollinators in its natural habitat, it can also do so by cloning individual sections of itself, which separate from their bases, die, and then grow into new plants on their own.
Unfortunately, this enigmatic and unusual cactus is officially listed as an endangered plant in Mexico, mostly because of illegal trade. Cactus collectors will spend a lot of money to include it in their personal succulent gardens due to its uniqueness. On the illegal market, a single creeping devil stem can fetch between $4000 and $5000.
However, the agricultural sector poses a threat to this amazing cactus as well. To make room for their grazing cattle, for which the creeping devil is both an annoyance and a barrier to grazing, farmers will decimate entire colonies.
Why are cactus pricks so painful?
Cactus spines are modified leaves that resemble needles. Cactus may lose less water in hot and arid environments because of its needle-like adaptability. Additionally, they give out some shade and are a fantastic deterrent to animals that might try to eat them.
Some cactus feature camouflage-producing spines, which further helps to defend them from predators who could try to consume them. Less light reaches the stem of the plant because the cactus spines reflect light (reducing water loss).
What types of cactus spines are there?
Various cactus plants may have one of a few different types of cactus spines. Some spine types could be more difficult to remove and hurt more when pricked. Types of cactus spines include:
- tiny, hair-like spines (such as in genus of Cephalocereus)
- Stiffened spines (such as in Mammillaria gracilis)
- rounded spines (such as in Sclerocactus papyracanthus)
- Glochids (such as in Opuntia rufida)
- bent spines (most cacti)
One of the sorts of cactus spines that causes the most discomfort is the glochid. This is due to the glochids’ brittleness and easy skin-breaking. This makes removing them from the skin extremely difficult.
This also applies to cholla or barbed spines. They are extremely painful and easily penetrate skin and soft tissues. These cacti belong to the Opuntioideae subfamily, which also includes Chollas and Cylindropuntia.
Because they adhere to flesh, clothing, and fur with ease, cholla cacti are sometimes known as jumping chollas. They must be carefully removed from the skin since if done by hand, they would cling to the fingers.
How do cactus spines function?

Scientist’s profile:
Answer:
Cacti are among my favorite plant species, and their needles undoubtedly make them distinctive. In many respects, the needles that cover cactus are essential to their survival. Since many cacti are found in dry environments, these plants need to store a lot of water in order to thrive. In fact, according to scientists, water makes up between 90 and 94 percent of a cactus plant. Cacti are ideal treats for thirsty species due to their high water content. Animals that consume cactus in the wild include quail, kangaroo rats, sheep, desert tortoises, as well as a variety of insects. In order to stop thirsty or hungry animals from eating or harming the plant, cacti contain needles.
Additionally, you could see that the color and texture of cactus spines might vary. While some spines are fluffy, others are stiff. The color of the spines can also vary, from white to gray to pink! Because of these variations in spine color and texture, cactus can more effectively blend into their surroundings (i.e. camouflage). Therefore, a second reason cacti have needles is to enable them to conceal from harmful species.
Heat is a significant issue in desert regions where there are many cacti. The needles of a cactus can offer protection from the sun so that it can thrive in these scorching temperatures. Although it may not seem like a single needle may offer much shade, several cacti species have needles that are grouped closely together. The plant is shaded by these spine clusters, which resemble small umbrellas. These spines provide shade for the cactus, which helps keep water from evaporating and causing water loss.
All in all, cactus use their spines as protective and hiding mechanisms against potential predators. Additionally, they give the plant shade, which keeps it cooler and prevents water loss.
Does jumping cactus hurt?
Anyone who has come into contact with a jumping cholla cactus can attest to the fact that it is both excruciatingly painful and challenging to resolve because the cactus’ spines are notoriously difficult to remove.
Cactus spines have a variety of purposes, including defense and the storage of essential water in arid regions, although some are considerably more difficult to remove than others. Researchers have now determined the cause.
Microstructure Matters
The function of the spines, particularly their capacity to pierce animal skin, was tested by Stephanie Crofts and Philip Anderson of the University of Illinois on six different cactus species. Their findings, which were reported in the Proceedings of the Royal Society B, demonstrate that the microstructural characteristics that enhance a spine’s capacity to pierce flesh also raise the barrier to removal.
With their shingled, overlapping barbs, cholla and other barbed cactus spines in particular resemble porcupine quills. Compared to non-barbed spines, these barbs more easily pierce and entangle flesh.
According to Anderson in a news statement, “The barbs grab on your muscle fibers, making it tough to remove them.
The two also experimented with golden barrel, brittle prickly pear, and a few other common cactus species in addition to jumping cholla. They pierced skinless chicken breasts, hog shoulders with the skin still on, and a succession of rubbers with various densities to determine the structure of each plant after studying the spines under a scanning electron microscope to learn more about it. According to their experiments, barbed spines function as razor-sharp blades that may readily pierce skin.
According to Anderson, the cholla spine needs to be able to penetrate the target with just a mild brush in order to puncture the target efficiently. ” It must also be quite challenging to remove at the same time.

Stuck On You
Barbed spines, like cholla, emerged out of the chicken breasts with a tissue-coated exterior. The researchers believe that some of the barbs were left behind in the flesh because they did not emerge clean from the pork samples.
The plains prickly pear’s spines checked out took the most effort to remove from chicken breasts. On the other hand, cholla spines proved to be the most difficult to extract from pig tissue; tests revealed that one cholla spine was capable of hooking into flesh with sufficient force to lift half a pound of pork by the skin.
That’s both quite frightening and clever. Cholla spines also have a reproductive function. Chollas have spines that hook onto a person or animal’s muscle fibers so strongly that it frequently tears off a piece of the cactus, which is then moved to a new area and can start growing as a new plant.
