The Giant Japanese Hornet is an Intense Killer Machine

By Anupum Pant

For the sake of knowing, scientists have given the Japanese Giant hornet a name – Vespa mandarinia japonica – a name normally you need not remember. However, there is a thing you should always remember about them. See the picture of this insect below and remember what it looks like. And if you see it coming towards you while you are holidaying in Japan, just run for for your life. This is the Japanese Giant Hornet:

Yes, this giant hornet is a deadly killer machine. You should fear it because…

Well, first of all they are large and fearsome and have stingers that are more than 6 mm long. They use these to inject a relatively large amount of venom into the target – A kind of venom which attacks the nervous system and damages tissues. The venom is also known to destroy red blood cells, which can result in kidney failure and even death in some cases.

Secondly, just read what Wikipedia says about it…

Thirty to forty people die in Japan every year after having been stung, which makes the Japanese giant hornet the second most lethal animal in Japan after humans (bears kill zero to five people and venomous snakes kill five to ten people each year).

Thirdly, these hornets are known to move around in small groups of 20-30 individuals who manage to kill tens of thousands of bees in their own beehive, and then they steal their young ones. About 30 of these giant hornets can kill 30,000 bees in a single attack. They don’t just kill, they rip the bees apart mercilessly. Watch a video of them ravaging a beehive…

Also remember that it won’t come searching for you to sting you to death, until it senses threat.

Outperforming Humans – Speed

By Anupum Pant

Humans can use tools, communicate, count, make others laugh, socialize and are self aware too. We also have emotions and a pretty good memory. All of the things put into a single creature sure makes the “most advanced” creature we’ve ever known. But if these traits are considered individually, you’ll easily find an animal who beats us at one trait at a time. Today, I wanted to read and write about where humans stand when it comes to speed.

Talk about running speeds and the fastest person ever, Usain Bolt comes to my mind. A bolt indeed. As on date, if I’m not wrong, the world record set by him in the 100m race is 9.58 seconds. To put this human freak show into perspective, the average speed of the Jamaican sprinter in this race comes to about 37 km per hour (23 miles per hour).  And he’s clocked 28 mph somewhere in the race, they say.

In a world full of cars and planes, where distances travelled have become really huge, 28 mph sounds like a speed which does no good in our practical lives. And yet, it takes an Olympic runner to clock that speed. Normally, people run at about, say 10 mph. Damn!
The biological human limit to running speeds is estimated to be about 40 mph.

Quick fact: The fastest human objects ever are Helios 2 (a German probe) clocks about 150,000 mph. Another spacecraft, Juno does about 25 miles in a single second!

Now compare that with a Peregrine Falcon which can make use of the gravity and its perfectly aerodynamic body to travel at a speed of 216 mph (360 kph). But, that’s hardly any work for the animal. It’d the gravity making it fall.

In level flight, the white throated needletail (swift) can fly at speeds more than 100 miles per hour (up to 106). That’s the fastest bird if you do not count gravity assist.

An on land, of course the Cheetah takes the prize with about 70 mph of running speed. But, there’s a catch. If you measure speeds of animals relative to their body sizes, there’s a little blood sucking mite that beats cheetah by a huge margin.

The fastest swimming fish is the sailfish, which can swim and jump for small distances at about 70 mph.

Humans can swim at about 5 miles per hour.

Moving at 35 miles per hour a jack rabbit can travel faster than a human. The patas monkey, the fastest primate, runs at about 35 miles per hour too!

Now these are some animals you probably already know. Soon there’s more to come. In the coming days I wish to do a series on outperforming humans…Maybe I’ll write about endurance next.

Is Cheetah No Longer the Fastest Land Animal?

By Anupum Pant

Read this for the answer to the question above

If you haven’t previously heard of the Betteridge’s law of headlines, also known as the Davis’ law or the journalistic principle, here’s what it says:

Any headline which ends in a question mark can be answered by the word no.

(Of course, you aren’t supposed to take the “law” too seriously.)

Did you see the headline for this article? So, basically you can read no further and still say – No, Cheetah still is the fastest land animal. But if you look deeper, things sure get interesting.

Absolute Speed vs. Relative Speed

To be specific, Cheetah is the fastest land animal because its absolute speed on land is the highest (112 to 120 Km per hour). When you measure absolute speed, you don’t take into account anything other than the speed. The weight or size of the animal doesn’t matter. Here, Cheetah is a clear winner.

But, when you do take into account the body length of an animal and measure the speed in terms of, number of body lengths the animal can cover in a single second, there are number of other animals that beat Cheetah by a huge margin.

Here’s a fact – When running at full speed, cheetahs can cover the length of up to 16 to 20 cheetahs in a single second. That’s pretty fast. The fastest humans on earth can do about 10 – 11 body lengths per second. [Source] Do you know what’s the fastest animal of you measure speed relative to their respective body lengths? Wait for it…

It is a mite. Yes, a tiny little 1-2 mm Californian blood sucker can cover up to 322 body lengths in a single second! Scientists just found out about it. Graphic designers who’ve used elegant cheetah silhouettes to represent speed in their graphics will have to use a tiny blood sucker now? How disappointing!

By the way, 322 body lengths in a single second of a sesame sized animal translates to just about 0.8 km per hour of absolute speed. But, imagine this. If it (the Californian mite) were the size of a human being (which it is not), it would have moved at a whopping 2,100 km per hour. I know the physics of it would have been different in case it were that big. Since it is not, we aren’t even putting in the effort to consider those details at the moment.

In case someone comes searching for the scientific name of this mite, it is called – Paratarsotomus macropalpis (I won’t remember that)

Other land animals “faster” than the Cheetah

  • The Australian tiger beetle held the record before they found out about the tiny mite. The beetle can cover up to 171 body lengths in a single second.
  • The household cockroach is pretty fast too. It does about 50 body lengths in a single second.
  • The ghost crab can run at about 100 body lengths per second.

All of them, much “faster” than the cheetah (in relative speed). And still Cheetah always wins the race because it is absolutely the fastest land animal. Still. Please don’t trust the click bait titles like:

Killer Whale’s Ingenious Trick To Kill Sharks

By Anupum Pant

Background

Although mosquitoes are much much deadlier, Great White Sharks no doubt are dangerous animals too. It seems as if there’s nothing this big fish fears. But even this deadly hunter gets hunted.

On the other hand, Orca or the Killer whale is a relatively cuter animal. Remember Free Willy? But to me, these seemingly cute animals are in fact shrewd hunters who like to torture their prey before eating it. They’ve learnt well the tricks of the trade. I feel they are a lot like crows. That is to say, they are extremely intelligent and learn by observing.

For instance, to make seals sitting on ice pieces fall down, the killer whales know a good trick. They make waves and make the ice sheet wobble. As a result, seals fall down. Similarly, by sneaking up, making bubbles to trap fish and by using other such methods, these genius hunters make sure they get their prey.

Also, like Daniel Kish, they use echolocation. But Orcas use it to locate the prey. Still, their intelligence doesn’t always work.

Orcas kill sharks and they know a really efficient trick to do it successfully. They flip the sharks upside down. Here’s how they exactly manage to have “Shark sushi for lunch”.

Tonic Immobility + Ram Ventilation

To kill sharks they employ this very ingenious trick. They cash in on Tonic Immobility. Ironically, Tonic immobility is a defence mechanism some sharks use. Tonic immobility is something that a number of animals use for different purposes. Mostly they do it for defence by faking death.

During this state, their breathing becomes very relaxed and they might look as it they are dead. For instance, lobsters become immobile when they are stroked on their backs. Sharks can be flipped and they become immobile (not always). Everyone knows how Possums do it – they play Possum.

Now, since some sharks can’t breathe when they stop moving, due to something called ram ventilation, they drown. And isn’t that perfect for our Killer!

The killer whale  flips the shark, puts it to sleep. The shark stops breathing and dies. Then the killer whale goes and rips apart the tongue and liver of the shark, because that is all it eats. All the other parts of the dead shark drop to the sea bed.

Even these uneaten parts don’t go to waste, the other sea creatures have the time of their life eating them. They probably thank the odd little habit of the killer whale – the habit of eating just the liver and leaving everything else.

The Sweet Tale of the Mysterious Tree Lobster

By Anupum Pant

I do realize how big our world is and the sheer number of species that live in it. Also the fact that about 86% of the species are still unknown has me in awe all the time.

Yet, after having read about so many kinds of animals that live on our planet, after having documented them on this blog, I always feel that I’ve known and written it all. The very moment I start losing hope that I would never find an interesting animal ever again, something incredible comes across. Always!

Today, that happened again when I was reading an NPR blog. This time, there’s more than the species itself. The place where it lives is pretty awesome too. The most amazing part – This six-legged giant lives only there. That means, nowhere else on Earth will you find it! First, let’s see where it lives…

This is where it lives:

balls pyramid

I know, it looks like a CG mountain done for a fantasy movie. Trust me, it’s real. It’s called the Ball’s Pyramid (named after a European named Ball who first saw it in 1788) and was formed 7 million years ago due to a volcanic eruption. It is an awkwardly tall (1,844 feet) and an extremely narrow rock sitting in the centre of the sea. To the East of Australia, the red place marker in the following picture shows where the rock is located.

 balls pyramid location

 What lives there? And how was it found?

There is an island – Lord Howe island – close to the rock. In the island lived huge “tree lobsters” (actually they were huge stick insects with a hard exoskeleton – Dryococelus australis). In the year 1918, a ship crashed on the island and brought with it some rats. The rats loved these tree lobsters and finished them off within 2 years. After 1920, these tree lobsters were thought to be extinct.

tree lobster

Of course there were stories of these insects living on a rock near the island. But no human wanted to climb the narrow rock to hunt insects at night.

Only in the year 2001 when 2 researchers David Priddel and Nicholas Carlile decided to climb up the rock to find out if these stories were real, they found something incredible. Poop of a large insect. When the came back at night to investigate, the shiny black huge tree lobsters were found! These insects had probably never been extinct.

For more than 80 years, 24 of them had been living on this rock, in a bush and no one knew how they got there. Probably they clinged on to birds or something. Also, according to the researchers, these creatures have never been seen anywhere else.

Where are they now

I’m not sure about where they are now. According to the 2012 NPR article which I read, a pair of these creatures – Adam and Eve – were brought into Australia. Eggs got laid and little Tree lobsters came into the world. Thankfully, the species was saved from going extinct. But it isn’t known if they’ll be sent back to their home island because the great-great-great grandsons of those rats must still be there waiting to finish these insects off again.

This is how the first ones hatched in the zoo…

Platypus is a Very Strange Animal!

By Anupum Pant

Background

What would you get if you if you crossed a duck, frog & snake? Hint: It is a mammal and lays eggs!
You’d have one of the most weirdest and mysterious animal, the Platypus.

Knuckles the echinda.pngNote: Unlike what is popularly taught in schools, Platypus is not the “only mammal that lays eggs”. Echidna – Knuckles from Sonic the Hedgehog – is the second kind of mammal that lay eggs.

So, Platypus is considered a strange animal because, it secretive and even today, not everything is known about it. It has a beak that looks like a duck’s beak, it’s feet are webbed like that of a frog’s. Besides that, this cute & cuddly looking creature, found in the Eastern part of Australian fresh waters, uses venom like a snake. But there is more:

Some Incredible things about the Platypus

Firstly, it lays eggs and is not a reptile. It is one of those two mammals which lays eggs.

For up to 3 months the male Platypus stores the eggs in its bill.

They swim underwater with their eyes shut and come out mostly at night.

Venom: They have a sharp and hollow thumbnail (spur) in their hind legs that is venomous. The venom is strong enough to kill a dog (doesn’t kill humans, but is extremely painful). This is used only in self defense. And only males are venomous. I never knew they had venom, but since they are from Australia, I had expected that.

Electrolocation: Under water, they detect electrical signals to find insects, store them behind their bill, come up and then eat them. It uses electrolocation – sees using electricity – Like bats use echolocation.

Under their bill are about 40000 sensors arranged in longitudinal strips. These sensors can detect fluctuations in the surrounding electric field. Even something producing a very minor electric fluctuation at a distance – contractions in the muscles – can be detected by the Platypus.

Sharks do the same and this is the reason they attack and damage our internet cables under the sea.

Mechanical sensors:  Besides that 60000 mechanical sensors (push rods) are used to detect movement in the water. Scientists say that the information from the electrical sensors and mechanical sensors is combined by its brain to calculate the prey’s exact location.

No Nipples: The young ones feed on milk from the mother Platypus. This milk doesn’t come from nipples, it comes from modified sweat glands (not unique to platypus) under its body. It has no nipples.

They can eat their own body-weight in under a single day.

They find it hard to stay underwater because they have a natural buoyancy. Yet, they can use other objects to stay under water for a maximum of 10 minutes. Then they have to come up for air.

Babies: The baby Platypus does not have an official name. Some call it puggle (which is not correct). But the accepted word, “Platypup” can be used.

Yeti Probably Does Exist + Fun Yeti Facts

By Anupum Pant

The search for Yeti, the mythical human-like creature that is assumed to have been living in higher elevations of the Himalayas, has continued for several thousands of years. Back in the days of Alexander the Great, during the 326 BC, when he was in the Indus valley area, he learned from the local people about the Yeti and expressed a desire to see it. The local people failed to bring it to him. Since then, several encounters have been reported and shoddy evidence has been produced, but till date, no one has succeeded in capturing the creature dead, or alive.

Proven Existence of Yeti

An Oxford university Genetics professor, Brian Sykes claims to have found a solid evidence that proves the existence of the Yeti. Moreover, according to him, it is a sub-specie of the brown bear. Specifically, an hybrid of the polar-bear and the brown bear.

After thoroughly studying two of the DNA samples (40 years and 10 years old samples) of hair from a mysterious animal found in Ladakh and Bhutan he said:

I think this bear, which nobody has seen alive… may still be there and may have quite a lot of polar bear in it. It may be some sort of hybrid and if its behavior is different from normal bears, which is what eyewitnesses report, then I think that may well be the source of the mystery and the source of the legend.

Interestingly, the DNA samples were found to be a 100% match with those coming from an ancient Polar bear that walked in Norway about 100,000 years from now. During those times a Polar bear was almost like a brown bear, the brown bear was yet to evolve.

 Random Yeti Facts

  • Did you know, Yeti is also knows as the “Abominable Snowman” because the Tibetian word “Metoh-Kangmi” was mis-translated by a famous journalist as “dirty men in snow”.
  • There is a wildlife sanctuary in Bhutan that goes by the name Sakteng Wildlife Sanctuary which is dedicated to preserving the Yeti.
  • During the 1950s, the Nepal government issued formal Yeti-hunting-licenses which costed a massive $650 per Yeti. Otherwise, Yeti brings in a lot of business in Nepal. There are braded hotels and airlines named after the Yeti.(more at NatGeo)
  • Even in the virtual world, Yeti is a pretty popular creature. Games often like to include it as an easter egg. GTA San Andreas players claim that the Yeti can be found on the rocky faces of the Mount Chiliad at daytime. They say it is hard to see because it blends in with the mountain due to its color. GTA V players have encountered a similar beast, the BigFoot.

Ming – A 507 Year Old Organism Killed By Scientists

By Anupum Pant

A few years before Leonardo da Vinci started painting the Mona Lisa, somewhere deep in the ocean, in the year 1499, a clam was born. When it stepped into this world, it was also the period of Ming Dynasty in China, so several years later the clam was named ‘Ming’ (Scientific name: Arctica islandica) by scientists. Ming was the 507 year old organism that unfortunately got killed.

Like crocodiles, clams are also one of those biologically immortal organisms. This one lived on for 507 years till the year 2006, when it was discovered by a group of researchers in deep oceans. Unaware of its age, researchers stored it like all the other 200 clams they had gathered, using refrigeration, which killed it (and the others). It was an unfortunate accident; definitely not intended in any way.

World record: Ming the clam was recorded as the oldest individual animal ever discovered. The record mentions “Individual” because often colonies are recorded to live for really long times. By those measures, this clam would have stood nowhere in comparison. For example the deep-sea black and gold corals 2700 years old have been found. But, scientists are pretty sure that there are older individual organisms [than Ming] still living out there, waiting to be discovered.

Why do they live so long?

Their genes, extremely slow oxygen intake and very slow metabolism are some of the known factors that enable these clams to live for centuries. Their age is measured accurately by using Radiocarbon dating.

The Rings: But more importantly these clams have rings on their shells. These rings are like our fingerprints, unique for each clam. The number of rings on the shell also gives a pretty accurate estimate of their ages; like rings on a tree stump help us to find the age of a tree. Initially, a few researchers, using these rings, wrongly estimated the age of Ming to be around 400 years. It was corrected later by others.

The oxygen isotopes present on the rings can be detected too. These measurements give scientists a useful insight about the climate changes that must have happened over the years.
