World’s Largest Crocodile? (7+ meters/23+ feet)

A widely circulated photo over the internet which shows a giant crocodile with a bunch of villagers sitting behind. A story next to the photo saying “the people in a village on the Niger River in Africa were losing fellow villagers at a rapid rate, and called in the army, which shot a 7+ meters, 1200 kg crocodile.

Crocodiles often suffer from a prevalence of “big fish” stories and over-exaggeration. The photo below was first got shared on Reddit, and it started circulating rapidly since then. When I first saw the photo, I tried to guess the length of the crocodile, because it didn’t seem to me 7+ meters. I thought it was not more than 5 meters.

World’s Largest Living Cat: Hercules, the liger (video)

Ligers are the largest cats on Earth. A liger can be more than 900 pounds (~408 kg) in weight and 12 feet (~3.65 m) long, weighing almost 100 times more than house cats and almost twice as much as either Panthera tigris (tiger) or Panthera leo (lion).

The liger, the largest of all known extant felines, is a hybrid cross between a male lion and a female tiger.

A Japanese Giant Hornet cooked by Honey Bees (video)

In the insects’ world, the Japanese Giant Hornet (Vespa mandarinia japonica) is a real beast. It is one of the subspecies of the Asian Giant Hornet (Vespa mandarinia), which is the world’s largest hornet. As its name suggests, it is endemic to the Japanese islands, where it prefers rural areas where it can find trees to nest in.

A single Japanese giant hornet can kill up to forty European honeybees a minute. So, a few of them can decimate an entire colony containing 30,000 bees. Compared to honeybees, it is a really giant: adults can be more than 4.5 centimeters (1.8 in) long, with a wingspan greater than 6 centimeters (2.4 in). It also has scissor-like teeth which can wreak havoc on its prey.

Two kangaroos get into boxing match (video)

Somewhere in the Central Coast of Australia, two kangaroos are caught on camera in an intense boxing match on a suburban street. The marsupials can be seen punching and kicking each other close to houses in Central Coast, New South Wales. It is not clear where the action was filmed.

In this incredible video below, the funny fight goes on for more than five minutes. Luckily, both kangaroos were OK and not seriously harmed after the match.

Great white shark fight caught on camera (video)

The Great White Sharks, kings of the seas. They are fearless hunters. And they are big: a mature individual can grow up to 6.4 m (21 ft) in length (there are even reports of great white sharks measuring over 8 m (26 ft), and 3,324 kg (7,328 lb) in weight). According to Wikipedia, “The great white shark has no natural predators other than the Orca.” But this is not always true. Sometimes, great whites attacks and even hunt each other.

Even though the great whites are known to generally avoid conflicts with each other, the phenomenon of cannibalism is not alien to this species. This rare phenomenon, has been caught on camera recently: London-born diver Adam Malski (33) filmed a fight between two great white sharks 50 kilometers off the coast of South Australia’s Neptune Islands.

Will We Ever Visit Other Stars?

The Earth is our one and only home. As Carl Sagan said (Pale Blue Dot: A Vision of the Human Future in Space), “On Earth, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.”.

But will we ever leave our home and visit other stars in the future?

Our galaxy, “The Milky Way” is a barred spiral galaxy (a spiral galaxy with a central bar-shaped structure composed of stars) some 100,000-120,000 light-years in diameter, which contains 100-400 billion stars. It may contain at least as many planets as well. Our Sun (the Solar System) is located within the disk, about 27,000 light-years away from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm.

Sleeping cat and dog

I took these photos last week in Bodrum, Turkey. A stray cat and stray dog sleeping together in the same place, very closely. Beautiful.

The traditional belief that cats and dogs are natural enemies is not true. If appropriately socialized, cats and dogs may have relationships that are not antagonistic, and dogs raised with cats may prefer the presence of cats to other dogs. But unsocialized cats and dogs usually don’t like each other.
