1
Animal Camouflage Have you ever played the game Hide and Seek?
2
It's a fun game, huh?
3
You have to stay still and quiet and wait until the seeker passes you by.
4
Shh!
5
Don't let them see you!
6
Did you know that animals do something similar?
7
But for animals in the wild, it's not a game.
8
It is essential for survival.
9
Animals use camouflage to hide or fool predators that are looking for a meal.
10
Stick around and find out the many incredible ways animals use camouflage every day to stay alive.
11
In the wild, animals can either be predators,
12
which means they hunt other animals,
13
or they can be prey,
14
which means other animals hunt them.
15
To stay alive, every animal must adapt to its environment.
16
Camouflage can be a way for animals to adapt and help them survive.
17
Let's talk about the four basic types of camouflage that's used by animals.
18
The first is called concealing coloration or blending.
19
The second is disruptive coloration or patterning, disguise, and mimicry.
20
Let's look at each one in more detail.
21
The first type of camouflage used by animals is called concealing coloration,
22
or it can also be referred to as blending.
23
This type of camouflage helps animals blend into their background.
24
The white snowy owl and the polar bear are examples of animals that use concealing coloration as camouflage.
25
Their white fur blends in with the white snow around them.
26
It helps hide their movements as well as their location.
27
Squirrels, white-tailed deer, and various brown owls are made up of earth-toned colors.
28
These colors help them blend into the trees and dirt in their environment.
29
Disruptive coloration is the next type of camouflage we'll learn about.
30
It is often called patterning.
31
This type of camouflage breaks up the outlines of an animal making them difficult to see.
32
Patterning is used by animals with spots, stripes, or patterns.
33
The wavy stripes on a zebra help it blend in with the grasses surrounding it.
34
It might seem odd that black and white stripes could blend into grass that is green or brown.
35
But it works because zebra's main predator, the lion, is colorblind.
36
Did you know that?
37
Because lions are colorblind, the pattern of the stripes on the zebra are more important than the color.
38
When a herd of zebras are together,
39
their stripes merge, making them look like one giant striped animal.
40
It is confusing for the lion and makes it hard for them to pick out one individual zebra from the herd.
41
Some animals use their patterns to stand out as a warning to a predator.
42
Fish often swim in a group called a school.
43
They use their colors and disruptive designs to look like one big fish,
44
similar to what zebras do.
45
Lionfish use their bright colors to warn other animals to stay away from them and their painful spines.
46
Scorpionfish and sea robins are not very colorful animals,
47
but when they feel threatened,
48
they unfurl large, brightly colored fins to startle their predators so they can escape.
49
Our next type of camouflage is called disguise.
50
Disguise is when an animal appears to be something other than it really is.
51
It's kind of like wearing a costume on Halloween.
52
Do you like to dress up on Halloween?
53
It's fun!
54
An animal disguise is different than a costume because it's on all the time.
55
Remember our stick bug from the pictures at the beginning of this video?
56
Predators of the stick bug might mistake it for a part of a tree instead of its next meal.
57
You may have even strolled past a walking stick bug and didn't know it because it hides so well.
58
The Malaysian orchid mantis is also an example of this type of camouflage.
59
Look how beautiful that is!
60
What an amazing way to camouflage!
61
Other examples are a katydid,
62
which looks like a leaf,
63
a thorn bug, which looks like a thorn on a plant,
64
and a buff tip moth that looks like a twig from a birch tree.
65
Look at that!
66
Is it a bug or a piece of wood?
67
The last type of camouflage we'll discuss is called mimicry.
68
This is when animals or insects use their camouflage to pretend to be something it's not.
69
For example, some animals mimic something dangerous,
70
bad tasting, or poisonous, so a predator will leave it alone.
71
This is a great trick because predators are often fooled by the disguise.
72
Some great examples are the elephant hawk moth caterpillar,
73
the owl butterfly, and the scarlet snake.
74
Let's look at each one and see if you'd be fooled in the wild.
75
Our first example is the elephant hawk moth caterpillar.
76
It has two false eyes and moves its head around to look like a snake.
77
Another great example is the owl butterfly.
78
This butterfly has a large eye spot on the outside of each wing to make it look like an owl.
79
Would you be fooled if you were an animal looking for food?
80
Although it is not venomous,
81
it looks very similar to the coral snake,
82
which is venomous and alerts predators to stay away.
83
Did you know that animals don't just use camouflage to hide from predators?
84
Some animals use camouflage to help them hunt for prey.
85
Let's take a look at some animals that do just that.
86
Have you ever seen a leopard?
87
Its spotted coat can help the leopard catch its prey.
88
The spotted coat blends into the surroundings so that it can sneak up on its prey.
89
The unsuspecting prey cannot see the predator and is then attacked.
90
As we have learned, camouflage is often used to hide from predators or to fool unsuspecting prey.
91
But did you know that some animals use camouflage as a form of communication?
92
A chameleon is a lizard that can change its colors.
93
Maybe you already knew that.
94
Most people believe that it's to fool predators.
95
But in fact, the color change is used to communicate to other chameleons.
96
They communicate that there may be danger in the area.
97
Chameleons may change colors to attract a mate or as a reaction to their mood or environment.
98
Changing colors also helps their bodies adjust to temperature or light changes.
99
Let's review what you've learned today.
100
What type of camouflage helps an animal blend into its background?
101
The answer is concealing camouflage or blending.
102
Did you get it right?
103
True or false.
104
Animals only use camouflage to hide from predators.
105
False.
106
Some use it to catch their prey.
107
Great job!
108
True or false.
109
One of the reasons the chameleon changes its color is to communicate.
110
That's true!
111
Whether to help them hunt or to keep them from being hunted,
112
camouflage plays an important part in the survival of many creatures.

練習のコツ
動画のスピードとトーンを理解することは、英語の発音を良くするために非常に重要です。以下のステップを参考にして、効果的にシャドーイングを行いましょう：
- ゆっくりと聞く - 動画の最初は、全体をゆっくり聞いて内容を把握しましょう。
- フレーズごとに分ける - 一部のフレーズを切り出して、それを繰り返し練習することで、英語スピーキング練習を効果的に行えます。
- 声に出してみる - 音声を真似しながら声に出してみて、リズムとイントネーションを意識すると良いでしょう。
- 何度も繰り返す - 同じ部分を何度も繰り返すことで、記憶に定着させることができます。
- 実際の会話に生かす - 学んだ表現やフレーズを日常生活で使えるように練習します。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
