A Mean Creature from the Sea

By Anupum Pant

Stone fish is a bizarre looking creature, 15-20 inch sized, weighing about 5 pounds, is covered in dark patches and has ugly pimple like things all over its body. It’s found in the coastal regions of the Indian ocean and the Pacific ocean and likes to sit in between coral reefs and stones most of the time. The fish can survive outside of water for a whole day.

The fish is well-known as the most venomous fish. The most surprising thing about it is that it can be held in bare hands and you still won’t get poisoned.

However, a part of this fish can leave you dead in minutes. The fish has very sharp needle like things inside of skin sacks on its back, which when stepped on, are designed to inject an extremely powerful toxin into your body. The toxin is known to cause severe pain, paralysis and tissue necrosis. These venom spines can refill in about a week. Watch spines go in the video I’ve attached below…

Sad Story of The Lonely Whale – 52 Hertz

By Anupum Pant

Background Story

In the year 1989, a navy technician Joseph George, discovered something mysterious. While looking for enemy submarines in the sea by detecting sound signals, Joseph noticed that there was a mysterious lone sound which stood out in the acoustic signal. From his years of experience as an acoustic analyst, Joseph knew that this sound wasn’t coming from a submarine. As predicted, no enemy ships or submarines were found on further examination.

The sound was a deep pulsing wave and was incredibly loud. It seemed as if it were coming from a machine. But he was certain that this wasn’t a mechanical machine which was making the sound. There was something biological about it. So Joseph decided to call an experienced marine biologist to find out what was making that sound. The researcher confirmed that it was a whale! But not a normal whale…

Did you know?
Whale vomit can make you rich.
and Whale fat is a very healthy thing to eat.

The Twist

If this was really a whale, it still confused the marine biologist because first, the sound was coming from an awkward path. Since whales travel together in a regular migratory path, this wasn’t coming from any of those paths. Also, it was a lone sound.

Secondly, the frequency of sound that was detected was measured to be 52 hertz, and no species of whales were known to make that kind of sound. Usually whales create a sound with a frequency that lies between 15 to 20 hertz. This was definitely not any known species of whale. Or even if it was among any of the known species, it was calling out the wrong note. A note, probably no other whale could hear.

So, for obvious reasons, even when the loud bass was heard for several times, no response by other whales was detected. This was awkward because whales usually respond to the members of their groups. They talk. It was concluded that this whale was travelling alone. No one knew why.

Studies and Theories

In the 13 years of study that ensued, the whale (or whatever it was) was never seen, nor was a response to its song was noted. Scientists started calling it the 52 hertz whale. They could never figure out why the whale sang in a different voice or even an answer to why it was alone, travelling on a completely different path.

Scientists have tried to explain this, but there has never been a solid answer that explains the lonely nature of the creature. To explain the loneliness, some say that the 52 hertz’s voice can’t be heard by other whales, others say that it can’t hear the other whales. Some say that the other whales are scared to respond or go near an unusual voice. Other theories say that the whale must be a hybrid of two different species of whales and that is the reason it sounds so different. What is the real deal, no one knows.

Stories Documentaries and Poems

The 52-hertz whale started having a huge fan following in the late 2000s. A 90 minute documentary was made. However, I couldn’t find it anywhere. Poems were written. Blogs and statuses were written and people sounded touched & concerned. They wanted to extend help to the lonely whale in some way.

Bizarre Creature – The Tongue Eating Parasite

By Anupum Pant

Background

Firstly, if you are eating something, or you are weak at heart, then go away. It isn’t going to be a pleasant one today because we are going to look at a really bizarre, and probably one of the most grossest creature ever – The tongue eating parasite.

Not that it is really needed here, but in case someone comes searching for it, the scientific name of this isopod is Cymothoa Exigua. It is one of those very large group of animals that includes crabs and lobster – called Crustacean. This one lives in the ocean and is parasitic. That means this creature lives and benefits at the expense of the other, called the host (fish in this case).

Changing Sex

Protandry hermaphroditism: Another interesting thing about these isopods is that the adult males can turn themselves into females. When a creature changes sex from male to female, it is called Protandry. This changing of sex at some point in life is called Sequential hermaphroditism. So, the tongue eating parasite is a Protandric Hermaphrodite. But that isn’t even what we came here for…The main tongue eating part is coming…

The Life of Cymothoa Exigua

The life cycle of this parasite starts with these little ones attaching themselves to gills of, say a Snapper(or others). They enter the body of a fish through gills. When they mature inside, all of them are males. Later, since they are Protandric Hermaphrodites, one of these matured males turns into a female. During this time the males are still attached to the gill arches.

The male that turns into a female, goes to the base of the tongue of this fish and attaches itself to it. It feeds on the tongue and destroys it. Then the parasite attaches itself to the stub and starts acting as a prosthetic tongue!

If you are not in a mood to read, the woman in the video below explains it nicely.

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.

Author’s Note: This is the 50th post by me here which marks a 50 day anniversary. By now, I’ve become a happy blogger with more than 12K views already. Thanks all. Do take some time to check out the archives.

Sharks Are Not So Bad After All

By Anupum Pant

Sharks have been on earth for millions of years more than we have been here. Also, they haven’t changed much since a long time. The kind of sharks we see today, were the same sharks that existed 350 million years ago.

That means, modern sharks have lived happily for millions of years without eating humans. Even today, they aren’t very keen on killing us for food. They simply aren’t designed (or haven’t evolved) to do that. Humans were never a part of their normal diet. Instead, they normally feed on small fish. While a few other species of sharks may eat seals, sea lions and other mammals too. In fact, they can go on for months without food.

Funny as it may sound, sharks are scared of humans. When a shark sees a human in water, it gets confused and scared. It goes near to check,  and this usually results in an accidental bite. They don’t kill humans out of aggression. With 15 rows of razor sharp teeth on each jaw, even their gentle bites may kill a person. About only 20 out of 300 species of sharks are reported to have been involved in accidents with human beings.  About 100 such accidents occur every year.

Not being insensitive about human deaths: Can you estimate how many people do sharks kill every year? The answer is 10. Ten people, on an average are killed by shark bites every year. That is about 1/15 th of number of people killed by coconuts every year*
*Note: “150 people are killed by coconuts every year”, is a popular urban legend. The coconut death figure is a crude estimate or just a figure pulled out of thin air.

Nevertheless, the number of people killed by sharks every year is very very less (again, even a single human death isn’t really ‘less’). I’d rather not use statistics to prove my point. [image]

Why are sharks scared of us? … Why shouldn’t they be?
We kill about 100 million sharks every year. That is such a huge number when compared to number of people sharks kill every year. Again, statistics could be deceiving here. But we do get an idea. There is a massive difference in the number.
Why? Humans catch sharks for their meat, internal organs and skin,  to make products such as shark fin soup, lubricants, and leather etc. Some times, fins are cut and live sharks are thrown back into the sea, crippled. This eventually kills them due to excessive bleeding or other obvious reasons.

It is ironically that we move into their natural habitat and in turn blame sharks for destroying our boats, surf boards. Moreover, we are shocked to hear about reports of shark attacks on humans. Shouldn’t it be the other way round? We should stop looking at sharks as if they are the monsters; we are. At the same time, that doesn’t mean you should risk your life by going in shark waters to give it a high-five.

Random Science Fact:  

Only 14% of the Earth’s species are known to us. 75% of all the species on Earth will be gone within the next 300 years. Think about those species which will go extinct while we are here, and we’ll never know about them.
