Unique facts about jellyfish



- WATCH VIDEO: Learn some unique facts about jellyfish.

-OR READ THE SUMMARY:

Jellyfish can be found in every ocean and sea from the surface to the deep ocean floor. 

They are found in both tropical and cold water environments but they are most common around the equator.

Jellyfish are made up of at least 95 water meaning they need little food to survive. 

Jellyfish don't have a skeleton so they can move freely through any obstacles in their environment. 

They also don't have a central brain but instead rely on their tentacles for movement and sensing prey
the tentacles have cells called pneumaticists that contain venom or sticky threads known as kinetocytes.

The pneumaticists can catch prey and defend against predators by injecting them with Venom or immobilizing them with sticky threads. 

There are over 2 000 species of jellyfish in the world.

They come in a variety of shapes and sizes.

Some jellyfish can grow up to 15 feet long, while others are closer to the size of a thumbnail.

Smallest jellyfish can be found in the intertidal zones or estuaries where salinity may fluctuate throughout the day from fresh water to salt water.

The lifespan of a jellyfish is typically three months to two years.

The body can be composed of one or more layers depending on the species.

Some species of jellyfish can even produce electricity from their bodies that are strong enough to shock humans.

Jellyfish have a similar consistency as gelatin with an opaque white color due to their high content of proteins fats and carbohydrates therefore some people in Asian countries often eat them in certain dishes.

Jellyfish are not just animals that look like jelly they have an essential role in the ecosystem. 

They are a keystone species providing a vital function for the whole food web. 

Jellyfish provide habitat nutrients and food to many other species. 

Therefore, understanding jellyfish is essential for the conservation efforts of other marine life.

We hope this information has helped you appreciate the jellyfish.

How an ant can lift so much weight?



- WATCH VIDEO: Find out the main reason why ants can carry so much weight.


-OR READ THE TRANSCRIPT: 


Engineers have long marveled at how an ant can carry heavy objects more than its weight.

What is its secret?

Its secret is its neck structure.


Ant neck structure

 
Amazingly, according to the journal of biomechanics the neck joint of an ant can withstand pressures up to five thousand times the ant's weight.

Initially, scientists guessed that an ant might withstand one thousand times their weight judging by the leaves and prey they carry.

Thus these current findings were beyond expectation.

When humans carry only a third of their weight they may be unable to move fast after a few kilometers they may begin panting and require a break.

If you expect this to apply to ants then you are mistaken they can carry this weight effortlessly.

Ants accomplish even more when they work together you can see them carrying insects of considerable size through very uneven terrain and landscape.

Why are ants able to withstand those pressures with ease?


Withstanding pressure  


The researchers' micro ct scans of the ant's neck, reveal the unique interface between the soft and hard material connecting its head.

It explains why the ant's neck has unique properties of being both flexible and stiff at the same time.

However much remains to be learned on how the ants neck works this knowledge will greatly aid in making better robotic arms used in lifting objects.

They will be able to carry things that are more than their weight.

We hope this information has helped you understand why an ant is able to carry so much weight.
