Tigers have dominated the wild ecosystems in India for hundreds of thousands of years. The earliest remains of tiger fossils date back to more than two million years ago. These beautiful beasts have evolved to swim.
These wild cats play an important role in balancing several ecosystems, and therefore, their conservation has always been of prime importance across the world. It is said in the 1900s, around 100,000 tigers roamed worldwide.
Earlier, there existed about nine subspecies of tigers, but now, only six of them are present on Earth—the Bengal tiger, South China tiger, Indochinese tiger, Sumatran tiger, and the Siberian tiger.
The #BengalTiger accounts for the highest numbers, forming 50% of the total tiger population worldwide. The Royal Bengal tiger weighs about 330 kgs, while the Siberian tiger is about 13 feet long and weighs 660 pounds, which is equivalent to roughly 300 kgs.

The Sumatran tiger is said to be the smallest among these subspecies, weighing up to 310 pounds (140 kgs).
On the occasion of #InternationalTigerDay, which is celebrated every year on July 29, The Weather Channel brings to you some of the most amazing facts about these big wild cats.
Tigerskin is extremely unique and was among the highly valued trade commodity in the 19th century due to the bold patterns of stripes on the animal’s body.
Tigerskin displays mainly two colours—black and orange, derived from pigments eumelanin and pheomelanin, respectively. The production of the orange colour is caused by the gene SLC45A2.
The stripe patterns are unique to each wild cat. And that is how surveyors distinguish between two different tigers during the census. The gorgeous stripes run across the width of their body, and it is not just fur which displays this stripe feature, but the tiger’s skin as well.
Tigers have webbed toes
Unlike most cats, tigers love swimming and playing in the water. In fact, such is their love for water that they seem to have adopted a semi-aquatic lifestyle by living around the water bodies.
They have been observed to enjoy staying in water for longer durations, and are excellent swimmers. This in-built talent is enabled by their webbed toes, which makes it easy for them to push a greater volume of water.
A surprising fact about these apex predators is that they can easily swim across rivers at a stretch several kilometres.
The tiger cubs are born blind, and they only open their eyes six to twelve days after their birth. Even after that, they do not get their complete vision for at least another couple of weeks.
During these initial days, the cubs only follow the scent of their mother and are completely dependent on her for food and protection. They continue to tag around their mothers until they are about 24 weeks old.
A tiger’s roar is so loud that it can be heard from as far as three kilometres away. Moreover, one of the scientific studies revealed, the roar can also paralyze the other animals, especially some of its prey.
The main vocalisations of a tiger include roaring, growling, hissing, moaning, and chuffing. This majestic creature’s vocal chord is built in the shape of a square, which allows tigers to be extra loud. Their roars can go up to 114 decibels, as deafening as the jet engine.
The wild cats can easily mimic the call of other animals, this helps to successfully attract prey. Usually, they create a ‘pook’ sound of bears, thus creating a good trap.
While searching for life in the Gulf of Mexico, researchers pulled out a new bizarre-looking species of isopod, whose head resembles the Darth Vader from Star Wars!
This new-found crustacean, named Bathonymus yucatanensis, has 14 legs and is around 26 cm long — approximately 25 times larger than its closest relative, the common woodlouse.
While these blonde creatures seem pretty scary, the "Vanilla Vaders" are, in fact, harmless to humans.
Their huge size is only due to deep-sea gigantism — a phenomenon wherein ocean dwellers grow bigger than their terrestrial relatives due to lack of sunlight.
This super-Earth is a rocky world, on which a year is equal to just 11 Earth days.
The short orbit is down to the red dwarfs being a lot smaller than the Sun that centres our solar system. But the smaller sizes also make their gravitational fields less expansive than the Sun's.
Therefore, Ross 508b revolves around its red dwarf at a distance of just 5 million km. Mercury, in comparison, is about 60 million km from the Sun.
The short distance between this super-Earth & its red dwarf begs the question: how could it possibly be habitable?
#Japan is making grand plans of creating interplanetary #trains and champagne flute-like glass habitats in its bid to send and host humans on the #Moon and #Mars!
An interplanetary transportation system dubbed the 'Hexatrack', which maintains a gravity of 1G during long-distance travel to mitigate the effects of prolonged exposure to low gravity, has been proposed by #Japanese researchers.
The #trains will also possess 'Hexacapsules', which are essentially hexagon-shaped capsules with a moving device in the middle.
In 2012, the almost-complete skeleton of a new kind of #dinosaur was found in the northern Patagonia region of #Argentina.
The dinosaur has been christened #Meraxes gigas. The generic epithet is an ode to a dragon in the #GameOfThrones series.
Standing at the height of 11 m (36 ft) and weighing roughly 4000 kgs, the #dinosaur sported several crests, bumps and horns on its skull, which lent it a menacing appearance.
But the highlight of the findings is that the dinosaur had teeny-tiny arms, just like the #Trex!
Dr Jose, along with an international research team from the US, UK and Australia, will be examining the Galactic Centre Cloud (GCC) — the central molecular zone of our Milky Way — in April 2023.
They have been allotted 27.3 hours over the access period of 12 months.
