Inch worm
They have no legs on their abdomen Inchworms have three pairs of true legs at the front end but only two or three pairs at the rear. The inchworm moves by drawing its back end forward while holding on with the front then moves the front section forward while holding on with the back. A handful of other insects are known to prey on inchworms, the most dangerous of which are wasps. A female wasp will often lay its eggs inside an inchworm's eggs, allowing the wasp larvae to become parasites.

Zombie Ants?!?
The Fungus commonly known as "Zombie Fungus"
or scientifically known as Ophiocordyceps unilateralis
is a fungi that infects ants in the tropical regions of Africa.
This disease infects the ants brain and causes it to return
to its colony harmless but after 4-10 days of being infected
ant will have spores on its head that release the pathogen into the
air infecting other ants and causing the first infected ant to kill
or "eat" other members of its colony.
Gerenuk
- The Gerenuk live in Kenya, Tanzania, Ethiopia, and Somalia
- They eat tall bushs, leaves, and shoots
- Their predators are wild dogs and large cats
- They can live up to 13 years in captivity
- They weigh between 80-115
- They live in smaller groups
- The males have been known to violently fight with each other using their horns over territory
- They get all of their water from leaves
Video - Octopus Jumps Out of Water to Hunt Crab!
Check this out! It will give you a new respect for octopuses.
Questions for you to think about:
1. How do you think the octopus can shoot out of the water so quickly?
2. How is the octopus holding onto the crab?
3. How is the octopus going to get past the crab's exoskeleton?
Cordyceps ( Warning Do Not Watch If You Have A Weak Stomach )
cordyceps is a fungi parasite that goes in ants then it controls the ant to go where it wants to go spread its spores, making it like a zombie ant. in this video you'll learn one of natures craziest way to spread spores a zombie ant, when the ant gets taken over the fungi controls it to climb on top of a large plant such as a tree then it makes the ant stop and spread spores emerging from its head.
Guy holding the earth
This is a cool science picture. The photo is a guy holding the earth I thought this was really weird when I saw this it made me think a lot for some reason.

Creepy bugs live on YOU!!!!!!!!
This is a kind of creepy article that will educate you about something that you will never forget. YOU have microscopical bugs in your eyebrows!!!!!!! You can read about it here. We all have them in our eyebrows and eyelashes. You cant see them because they are about 0.3-0.4 mm long. If you are scared by this then read this article, it might make you feel better about yourself. (or nah)

What would happen if humans suddenly disappeared?
This video by asap science discuses what would happen if humans suddenly disappear. its crazy to think how much humans have changed the earth. This video shows us that the longest thing that survived is our trash. Some studies show that the US produce 220 million tons of trash per year (this is 30% of the worlds garbage per year). Enjoy the video and think about what YOU can do so that if we did disappear we wouldn't be remembered by fossils of waste that we would leave behind.

The Truth About Pigs
Here's the dirt on pigs: They are perhaps the smartest, cleanest domestic animals known - more so than cats and dogs, according to some experts. But pigs don't have sweat glands, so they roll around in the mud to stay cool. A sign of their cleverness came from experiments in the 1990s. Pigs were trained to move a cursor on a video screen with their snouts and used the cursor to distinguish between scribbles they knew and those they were seeing for the first time. They learned the task as quickly as chimpanzees.

The Tiger Beetle
The Tiger Beetle
This Beetle may be small and colorful
but it is very fast, infact it is faster than
the fastest human runner Usain Bolt.
He would have to run a 200m dash in
0.87 seconds to beat the speed of
the Tiger Beetle
White Kangaroo
Kangaroos are herbivores, which means their diet consists mainly of grasses. They can survive long periods without water. Kangaroosund in Australia and Tasmania, as well as on surrounding islands. Kangaroos live in varied habitats, from forests and land areas to grassy plains and savanna. Kangaroos live and travel in organized groups or "mobs," dominated by the largest male. Male kangaroos are called boomers, bucks or jacks; females are does, flyers, or jills, and the young ones are joeys. The collective noun for kangaroos is a mob, troop or court.

7 Myths About The Brain You Thought Were True
1.A bigger brain is beter no it is not.
2.allcolal doesn't kill your brain or drugs the only thing that can put a hole in your brain is physical.
3.They thought you had 100 billion brain cells but scientists found out you only have 86 billion.
4. Are brains think that 1mill seconds=12 days as baboons think 1mill seconds is 13 days.
Chameleon
Chameleons are amazing animals that are naturally known for changing colors. I have already made a post about why and how they change colors. But did you know that males are more colorful than females?
- Male chameleons usually have more vibrant and bright colors than females, partially for mating reasons.
- They are also insectivores, meaning they only eat insects. Their diets contain of fruit flies, house flies, grasshoppers, mealworms, waxworms, hornworms, crickets, and dubia roaches.
- Veiled chameleons are native to Yemen and southern Saudi Arabia. They live in rain forests and live in the trees close to the top where it's warm so that they can get lots of sunlight and basically just chill up there.
This is interesting to me because I got a veiled chameleon yesterday and had to study a lot about them before I could get him.

Poison Dart Frog

is so toxic, but some can assume that it comes from
truth because most of the poison dart frogs raised
Poison Dart Frog
Though this frog may seem beautiful with its colors,
It is one of the smallest and the most poisonous creatures
in the world. This frog holds enough venom to kill
10 grown men. The venom of this frog has been used
In blow darts and dart guns by Columbia for years.
Scientists are not exactly sure of how the blue dart frog
Its prey such as ants, termites, and beetles. This idea has
in captivity do not develop any venom.

Can We Control Our Dreams?
Can we control what we are dreaming of? I've always wondered that, mostly because I can never remember my dreams. What do you think? Can you make yourself dream what you want? After watching this video, you'll know the answer. :)

How to Erase Bad Memories
It is possible for long term memories to be dissolved if drugs are given a specific time. Studies have shown that if a person is given a small electric shock to the brain after remembering a past event, it could help that person forget many or all of the details.
42 people with severe depression took part in the study.
Scientists had already known that elctroconvulsive therapy can muddle a patient's memory, but they had figured out a way to turn this into a benefit. They found out that they could target which details would be forgotten by administering the shock shortly after the patient recalled the details.
Each patient had to listen to two upsetting stories while looking at a series of pictures. After this, the patients were forced to remember the details of the events in the stories. Neuroscientists found that remembering a story in a way like this could make memories more susceptible to change.
Immediately after recalling the details of one story, the patients were out to sleep. While unconscious, most patients received an electrical shock to the brain. One day later, each patient took a multiple choice test o n details about both stories.
Patients who did not get electriconvulsive therapy remembered the details of both stories pretty well. Patients whose brains had been shocked only remembered the details if one story well. The one they remembered was the one they had NOT thought of just before the treatment. Details if the story the patients had though about just before being jolted were recalled poorly. In fact, the patients scored no better remembering these details than if they had merely guessed at the answers.
These results suggest that electriconvulsive therapy can diminish recall of anything a patient had been thinking about just before treatment, though it took a day before the fuzziness to begin working.
While electriconvulsive therapy may never be an appropriate method for simply getting rid of bad memories, it can help people already receiving treatment. For them this may help them to get control over crippling memories. For instance, a patient may target a troubling memory to be wiped out just before treatment.
A big concern is making sure that this will no affect good memories and well as the bad. The solution may require NOT thinking about them immediately before being shocked.
Can plants think?
This is a video about plants. There are lots of cool things about plants like that they create oxygen through photosynthesis but this is something that I wonder about sometimes: Can plants think? This video will answer that question.
