1
Awww, Kitty's thirsty.
2
Just a little longer little Kitty.
3
We'll find something.
4
Look!
5
A cactus!
6
They have water!
7
Wait Kitty, don't touch it.
8
That could be risky.
9
Why?
10
Let's explore that by answering a prickly question.
11
What if you get pricked by a cactus?
12
Zoom in!
13
You're out on a hike,
14
enjoying the sun, maybe not paying full attention to where you swing your arm and suddenly, ouch!
15
You'll be rushed against a cactus.
16
It feels like a tiny army of needles has attacked your skin.
17
Before you blame the plant for being mean,
18
it helps to understand why the cactus has these pointy spines in the first place.
19
You see, long ago, the ancestors of modern cacti had flat ordinary leaves.
20
But living in deserts created a serious problem.
21
Regular leaves lose water quickly through evaporation.
22
And in a place where rain is rare, that's dangerous.
23
So over millions of years, their leaves shrank, hardened and eventually turned into spines.
24
These spines reduce water loss because they have very little surface area.
25
Spines not only help keep predators away,
26
but also provide shade, reflect sunlight and even insulate the plant when desert temperatures drop at night.
27
In other words, a A cactus's prickliness is really a survival strategy.
28
Some cacti, like the prickly pear, take defense to the next level.
29
They have long visible spines that look like toothpicks.
30
But they also have tiny hair-like structures called glochids.
31
These are small, often almost invisible and covered in microscopic,
32
backward-facing palms, like miniature fish hooks.
33
They slide into your skin easily, but pulling them out is much harder.
34
If that happens and you get pricked, the immediate sensation might feel like a bee sting.
35
Your skin may turn red and start to swell.
36
In most cases, that's the extent of the injury.
37
Temporary irritation that fades over a few days.
38
However, the reason it can hurt more than you expect is partly mechanical and partly biological.
39
The barbed structure anchors the spine into your skin
40
and your immune system reacts to this foreign object by sending inflammatory cells to the area.
41
That response causes swelling, warmth and tenderness.
42
Occasionally, problems can go beyond simple irritation.
43
Cactus spines can carry dust, soil and bacteria.
44
If fragments remain embedded in the skin,
45
They may trigger prolonged inflammation or in rare cases, infection.
46
Signs of infection include increasing redness, pus, worsening pain or fever.
47
That's when medical attention becomes important.
48
So, what should you do right away?
49
Act quickly but calmly.
50
Use clean tweezers to pull out larger spines with a steady motion.
51
Four glockens pressing adhesive tape or a thin layer of glue over the area
52
and peeling it off can help lift out tiny fragments.
53
After removal, rinse the area thoroughly with running water and mild soap.
54
Cover the area with a clean bandage and monitor it for a few days.
55
In the end, a cactus prick is usually more dramatic than dangerous.
56
It's a reminder that plants are not passive decorations, but living organisms shaped by evolution.
57
So, while in the desert,
58
keep an eye on your surroundings and admire the plants with a with a bit more respect and from a safer distance.
59
Trivia Time!
60
Did you know the saguaro cactus found in the Sonoran Desert in Arizona
61
and Mexico can typically grow 40 to 50 feet tall and weigh several tons?
62
Also, these slow growing giants can live over 200 years.
63
