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.
What do cacti that jump do?
If you approach too closely, this cactus will splinter off and fling itself at your face. What could be scarier than a mind-controlled cactus? Kidding. 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.
How can a jumping cactus be controlled?
Jumping cholla can be sprayed, but the main challenge is getting the chemical through the dense spine covering to the waxy pads below. The contact herbicide’s ability to stick to the cactus for a longer period of time and remain there increases with the addition of a surfactant, such as diesel fuel or dishwashing soap. Read labels carefully because new and more powerful herbicides for waxy cactus like leaping cholla are always being produced. Contact herbicide sprays containing triclopyr combined with diesel fuel or other oils are a gradual but successful treatment, according to the University of Florida IFAS Extension website. It often takes this herbicide several months to completely coat the pads and kill the plant.
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.
Are poisonous jumping cacti common?
A bouncing cholla section may strike your face, another person’s face, or a pet if you try to shrug it off. To get rid of it, use sticks or a big comb. Segments may fly in a high wind and strike anyone nearby. According to KCET, a reflex to suck the uncomfortable glochids out of the skin can result in them becoming embedded in the soft tissues of the mouth, tongue, throat, and windpipe, which might be fatal.

Are cholla’s needles shot?
There are more than 20 species of cholla cactus (genus Cylindropuntia), which are also known as buckhorn cholla, Arizona pencil cholla, walking stick cholla, and teddy bear cholla. They are notorious for having barbed spines that stick to human clothing and skin, as well as to the fur of animals, and they flourish in the southwestern desert regions of North America and northern Mexico.
The term “cholla” describes a group of cacti with shrub-like appearances and cylindrical stems constructed of segmented joints. The stems are really branches that serve a number of purposes, including photosynthesis, flower production, and water storage.
The numerous cholla cactus species “The needle-shooting cactus has adapted to the terrain and altitudes of the hot southwestern deserts. Some of them grow in forests at high altitudes, while others do so on the rocky, steep foothill slopes. The majority require rocky, draining soil.
According to the soil and weather, many kinds bloom in April, May, or June. They have blossoms that are either orange, green, or a combination of the two. In addition to having varied numbers of spines, joints and stems also differ in length, width, color, and shape.
Chollas can be as short as 12 inches, like the devil and club chollas, and as tall as 15 feet, like the chain-fruit cholla. They can also grow as shrubs, trees, or ground plants. Some species form large groups “many hectares of woodland.
Like the majority of cactus, chollas have tiny projections on their stems called tubercles that resemble warts. They develop their sharp spines here. The only cactus with papery sheaths covering the spines is the cholla, which makes it special. The spines of many chollas are vividly colored, giving this cactus its distinctive appearance.
Glochid clusters, tiny barbed spines that develop slightly above the plant’s typical spine clusters, are another characteristic that makes this species of cactus special. Once they enter skin, the red or yellow glochids are difficult to see and remove because they easily separate from the pads or stems.
Cacti leap out of pots, do they?
The colloquial name “jumping cholla cactus” (pronounced “KOY-ya”) is frequently used to refer to both Cylindropuntia bigelovii and Cylindropuntia fulgida. The former is known as Chain Fruit Cholla, while the latter is known as Teddy Bear Cholla. Both forms of the plant have joints that branch from the main trunk. Those joints fly off the plant and attach themselves to anything nearby with ease. The joints have sharp spines that stick to things like burrs. These cacti make great container plants if they are given the proper care.
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.
Hand Grubbing
Cholla can be easily controlled by “grubbing with a pick mattock.” Remove the plant from the area by cutting the main root 24 inches below the surface. Regrowth should only occur in the case of immature plants that aren’t yet apparent if you meticulously remove the area. Dry the scrubbed plants by piling them. Broken joints shouldn’t be dispersed because sprouting could happen. When dried, burn the heaps to stop growth around the cholla. Rubbing minimizes re-infestation from dispersed joints during winter or drought years.
Mechanical Grubbing
By attaching a toothed fork to a front-end loader of a tractor, you can mechanically uproot cholla plants. When the cactus is uprooted, slide the fork under the plant and gently lift. To catch as many of the fractured joints as possible, tilt the bucket. Before discarding, two or three plants might be uprooted.
Mechanical grubbing is not always effective since, if the tractor operator is not careful, substantial re-infestation may take place. Avoid scattering the joints when removing the cholla from the ground. To give yourself the best chance of success, pick the best grubbing year. If the cactus is rubbed in December, January, or during a drought-stricken summer, it is more prone to dry out.
A walking cactus is what?
Researchers have found what they are referring to as the missing link in China: a walking cactus. Arthropods like spiders and strange-looking worm-like critters are supposed to have evolved from the same ancestor, the walking cactus.
Walking cactus: An illustration of the missing connection between lobopodians and arthropods, the walking cactus.
Written by Wynne ParryLiveScience
An major gap in the history of the development of insects, spiders, and crustaceans may have been filled by the discovery of the fossils of a 10-legged wormy creature that lived 520 million years ago.
The so-called walking cactus is a member of the lobopodians, a class of extinct worm-like organisms presumed to be the ancestors of arthropods. Arthropods, such as spiders, have segmented bodies and limbs with joints that are protected by a hard shell.
All lobopodian remains had soft bodies and soft limbs prior to the discovery of the walking cactus, Diania cactiformis, according to Jianni Liu, the primary researcher who is connected to Northwest University in China and Freie University in Germany.
According to Liu of LiveScience, “Walking cactus is highly important because it is sort of a missing link from lobopodians to arthropods.” “Arthropods are thought to have descended from lobopodians, but up until recently, there was no fossil that could be used to prove that the first arthropod to have jointed legs existed. Walking Cactus demonstrates this.” [Fossilized walking cactus image]
Based on the discovery of 30 incomplete fossils and three complete ones in the southern Chinese province of Yunnan, Liu and other researchers characterized the extinct animal. The walking cactus was roughly 2.4 inches (6 cm) long and had a body divided into nine segments with ten pairs of hardened, jointed legs.
It’s unclear how the lanky worm supported itself. According to Liu, the animal may have utilized its proboscis, a tube-like mouth, to suck small creatures from the mud or its spiky front legs to seize its prey.
Modern velvet worms, which are thought to be the only living relatives of all arthropods, have preserved clues to the evolution of arthropods. These land-dwelling worms, once mistaken for slugs, are almost entirely soft-bodied save from their tough claws and teeth.
According to Graham Budd, a professor of paleobiology at Uppsala University in Sweden who was not involved in the current study, the discovery of the walking cactus helps fill in the evolutionary history between the velvet worms and contemporary arthropods, which are, in terms of numbers and diversity, the most dominant group of animals on the planet.
According to Budd, the walking cactus is the first and only instance in which an organism that cannot be identified as an arthropod has rigid, jointed limbs designed for walking.
Budd is not, however, persuaded by the researchers’ claim that the hardened legs of the walking cactus were directly handed on to contemporary arthropods.
He told LiveScience, “I am not convinced that it is a direct ancestor or as closely connected to live arthropods as they imply. I would like to see more proof, but the good news is that new information continues emerging.
For instance, it’s plausible that the walking cactus has little in common with contemporary arthropods and that its stiffened legs have undergone various evolutionary processes. According to Budd, it’s also likely that the bodies of early arthropods hardened before the legs did.
He said that recent years have seen a rise in scientific agreement on the evolution of arthropods as a result of new fossil discoveries, particularly those from China.
