As sensational as shark attacks are in newspaper headlines, the reality is that you’re more likely to be bitten by another person than a shark.

Crocodile babies, called hatchlings, are about 30 cm long. They stay with their mom for up to
two years.
A Nile crocodile mom makes her nest deep in the ground near a river. She lays about 50 eggs there, then guards them well to make sure they’re safe. When she hears a chirping sound she knows that the babies are hatching and has to dig them out and carries them to the water.

Symmetry is beautiful—to insects, birds, mammals, all of the primates, and people around the world.

Female scorpionflies seek mates with uniform wings. Barn swallows like partners with well-proportioned tails. Monkeys are partial to symmetrical teeth. If you walk into a village in New Guinea and point to the most beautiful man or woman sitting around the campfire, the natives will agree with you. And when researchers used computers to blend many faces into a composite “average” face, both men and women liked the average face better than any of the individual ones.
It was more balanced. Even two-month-old infants gaze longer at more symmetrical faces.
Creatures with balanced, well-proportioned ears, eyes, teeth, and jaws, with symmetrical elbows, knees, and breasts, have been able to repel bacteria, viruses, and other minute predators that can cause bodily irregularities. By displaying symmetry, animals advertise their superior genetic ability to combat diseases.

Monogamy & The Animal Kingdom

Monogamy is a form of relationship in which an individual has only one partner during his or her lifetime or at any one time (serial monogamy), as compared to polygyny, polyandry, or polyamory.
Maybe you thought that being faithful is reserved only for humans, but as it turns out, monogamous relationships are not reserved for us only. Here are some of the animals that find a mate for a lifetime:
wolves
bald eagles
barn owls
beavers
french angelfish
some bats
foxes
otters
swans
albatrosses
It might be a treasured value in many human cultures, but monogamy is rare in the animal kingdom at large. Of the roughly 5,000 species of mammals, only 3 to 5 percent are known to form lifelong pair bonds.

Have You Ever Eaten A Spider?

Does the Average Human Consume Four Spiders per Year While Sleeping?
No! In fact, it’s unlikely that a spider would let itself get swallowed by a person. To get swallowed, a spider would have to climb or fall into a person’s mouth. And a spider’s sense of self-preservation - its will to live - would keep it from climbing in.
If a spider happened to crawl near a sleeping human’s mouth, the spider would hear breathing. To a spider, that’s the sound of an enemy. Its instinct would be to flee, not to climb in.
But could a spider fall into a sleeping person’s mouth? Not likely. Adult spiders just don’t fall that often. However - and maybe this is where the myth comes from - baby spiders do fall, or float, through the air when they hatch out of their egg sac.
In fact, when one spider egg sac hatches, hundreds of too-small-to-see baby spiders get thrown into the air. They “ride” the air current to wherever they land. Sure, some of these baby spiders might land in the mouth of a sleeping person. And they might get swallowed. But the chance of an egg sac happening to hatch near a sleeping person is pretty slim.
And the chance of the sleeping person’s mouth being open and facing upward isn’t all that great either.
So, while it’s possible, it’s highly unlikely that the average person swallows four spiders
per year.

Reindeer have golden eyes in summer and blue eyes in winter.
What this change in color helps reindeer eyes do is capture more light during the dark winter months in the Arctic.

90% of all jellyfish are smaller than a human thumbnail.
Irukandji jellyfish, for example, are small and extremely venomous box jellyfish that inhabit marine waters of Australia and which are able to fire their stingers into their victim, causing symptoms collectively known as Irukandji syndrome.

The giant palm salamander can stick its tongue out 50 times faster than you can blink.
The giant palm salamander of Central America shoots out its tongue with more instantaneous power than any known muscle in the animal kingdom, a new study finds. It can extend its tongue more than half its body length in about 7 milliseconds, or about 50 times faster than an average eye blink.

A limpet is an aquatic snail with a shell that is broadly conical in shape.
Limpets use a tongue bristling with tiny teeth to scrape food off rocks and into their mouths, often swallowing particles of rock in the process. Engineers in the UK have found that limpets' teeth consist of the strongest biological material ever tested. |

Another interesting thing about them is that when threatened, a limpet can run away at a speed of two inches (2cm) an hour.

Ladybirds can fly as fast as racehorses can run.
For the first time, a detailed study has shown the creatures travelling at heights in excess of 3,600ft and reaching speeds of 37mph.
Researchers also examined the stamina of the insects and found that they were able to remain in the air for up to two hours.
Up until now, scientists believed that anything over seven foot was a long-distance flight for a ladybird - but the new data shows they can actually travel up to 74 miles in a single flight.

Reindeer are various colours, including white, dark grey, and brown.
The only female deer to grow antlers are reindeer. Each summer, both males and females grow their wonderful racks, but males usually shed theirs in late November to mid-December. Females keep their antlers until spring. Because all of Santa's reindeer are depicted with antlers, one might conclude that every one of them, including Rudolph, is female.

10 fascinating facts about woolly mammoths

When the Pyramids were built woolly mammoths still roamed the Earth.
- Contrary to common belief, the woolly mammoth was hardly mammoth in size. They were roughly about the size of modern African elephants.
- The ears of a woolly mammoth were shorter than the modern elephant’s ears.
- Scientists can discern a woolly mammoth’s age from the rings of its tusk, like looking at the rings of a tree.
- The woolly mammoth was not the only “woolly” type of animal. The woolly rhinoceros, also known as the Coelodonta, co-existed with the woolly mammoth, walking the Earth during the Pleistocene epoch. Like the woolly mammoth, the woolly rhino adapted to the cold with a furry coat, was depicted by human ancestors in cave paintings and became extinct around the same time.
- Cave paintings drawn by ice age humans show the important relationship they had with the woolly mammoths. The Rouffignac cave in France has 158 depictions of mammoths, making up about 70% of the represented animals that date back to the Upper Paleolithic period. There is also evidence of the use of bones and tusks by humans to create portable art objects, shelters, tools, furniture and even burials.
- Today, the hunt is on for woolly mammoth tusks in the Arctic Siberia. Due to global warming, the melting permafrost has begun revealing these hidden ivory treasures for a group of local tusk-hunters to find and sell. A tusk can range from 10-13 foot in length and a top-grade mammoth tusk is worth around $400 per pound. Mammoth ivory, unlike elephant ivory, is legal.
- The first fully documented woolly mammoth skeleton was discovered in 1799. It was brought to the Zoological Museum of the Zoological Institute of the Russian Academy of Science in 1806 where Wilhelm Gottlieb Tilesius put the pieces together.
- The coat of a woolly mammoth consisted of a “guard” of foot long hairs, and an undercoat of shorter hairs. Preserved mammoth hair looks orange in color, however researchers believe the pigment was changed because of prolonged burial in the ground.
- Even a kid can discover a preserved mammoth. In September 2012 in Russia, an 11-year-old boy named Yevgeny “Zhenya” Salinder happened upon an extremely well-preserved woolly mammoth carcass while walking his dogs. The remains were of a 16-year-old male woolly mammoth that died about 30,000 years ago. The discovery helped scientists conclude that the large “lumps” on a mammoth’s back were extra stores of fat to help it survive winters. The mammoth was nicknamed “Zhenya.”
- The final resting place of woolly mammoths was Wrangel Island in the Arctic. Although, most of the woolly mammoth population died out by 10,000 years ago, a small population of 500-1000 woolly mammoths lived on Wrangel Island until 1650 BC. That’s only about 4,000 years ago! For context, Egyptian Pharaohs were midway through their empire and it was about 1000 years after the Giza pyramids were built. The reason for the demise of these woolly mammoths are unknown.
