3 Fun Facts about Butterflies

1. Butterflies taste with their feet

But this is one of the ways butterflies tell what plants to lay their eggs on. They have tastesensors on their feet, and by standing on a leaf, they can taste it to see if their caterpillars can eat it. Most adult butterflies can't bite or chew.

2. Their eyes are made of 6,000 lenses and can see 

ultraviolet light.

Butterflies have two different types of eyes, single and compound. The one pair of simple eyes, ocelli, are single chambered and are primarily for determining light brightness. They are unable to focus on an individual object. The compound eyes are multifaceted and are used for their main eye sight. The light comes through one facet and is received by one rhabdom, similar to human retinas. Butterflies are able to see light wavelengths from 254 to 600 nm, this includes ultraviolet light, a light that we are unable to see. People can see only 450 to 700 nm. Flicker-fusion rate is the rate at which the light flickers to form a continuous image. For butterflies to see while flying their flicker-fusion rate is up to 250 times higher than it is for people. Our flicker-fusion rate is between 45-53 flickers per second. 

3.Skipper butterflies fly so fast they could outpace a 

horse, but most butterflies fly at 5 to 12 miles per hour(8 

to 20 kilometers per hour).

Certainly, some fast-flying skippers can fly 30 miles per hour or faster. Slow flying butterflies probably fly five miles per hour or a little faster. During fall migration, migrating Monarchs (Danaus plexippus) have been seen flying by tall buildings such as the Empire State Building at more than 1,000+ feet.

5 Fun Facts about Dolphin

1.Dolphin are smart

Known for their playful behavior, dolphins are highly intelligent. They are as smart as apes, and the evolution of their larger brains is surprisingly similar to humans.

2,Dolphin does not fully fall asleep

Dolphins have to be conscious to breath.[1] This means that they cannot go into a full deep sleep, because then they would suffocate. Dolphins have "solved" that by letting one half of their brain sleep at a time. This has been determined by doing EEG studies on dolphins.

3.Echolocation

Dolphins have developed the ability to use echolocation, often known as sonar, to help them see better underwater. Scientists believe this ability probably evolved slowly over time.Echolocation allows dolphins to “see" by interpreting the echoes of sound waves that bounce off of objects near them in the water.

4.The smallest dolphin

Maui's dolphin or popoto is the world's rarest and smallest known subspecies of dolphin. They are a subspecies of the Hector's dolphin. Maui's dolphins are only found off the west coast of New Zealand's North Island.

5.Two stomach

Dolphins have two stomach parts. One stores food and the other digests the food.

5 FUN FACTS ABOUT BIRDS

1.The earliest known bird, Archaeopteryx lithographica, lived about 150 million years ago during the Jurassic Period.

Archaeopteryx possessed a blend of reptilian and avian characteristics. It had feathers and wings but instead of a bill it had a reptilian snout. Archaeopteryx did not have a keeled breastbone, a key feature for flight, so scientists are uncertain whether it was capable of true flight or if it merely glided.

A total of ten Archaeopteryx fossil specimens have been unearthed over the years. All of these fossils were recovered from the limestone deposits in quarries near Solnhofen, Germany. The first Archaeopteryx skeleton, now known as the "London Specimen", was discovered in 1861.

2.Hummingbirds is the only bird that can fly backwards

Hummingbirds beat their wings as fast as 50 times per second, the fastest of any bird on the planet. This speedy wing beat, plus a rotating wrist joint, allows a hummingbird to hover in place, to fly backwards and upside down, and to catch tiny flying insects. 

3.The all eater

Roadrunners eat almost anything they can catch: lizards and snakes, small rodents, scorpions and tarantulas, and large insects. They'll even leap up to catch hummingbirds at nectar feeders. 

4.The sign of spring

Robins are often considered the first sign of spring, but not all robins leave their home range in winter, so their appearance is not really a sign of spring.

5.The great ''swallower''

A barn owl can swallow a large rat whole. After digesting its meal, the owl coughs up a pellet containing the rat's bones and fur. 

5 FUN FACTS ABOUT FROGS

1.Frogs don’t drink water with their mouths; they “drink” by absorbing water through their skin.

Frogs have permeable skin, which means liquids and gases can pass through it. There is a bad side to having permeable skin, though. Frogs are at risk of absorbing whatever pollutions are in the water and air, and they can easily get dehydrated if they are away from water for too long.

2.The translucent skin frog

The glass frog has translucent skin, so you can see its internal organs, bones and muscles through its skin. You can even observe its heart beating and its stomach digesting food.

3.The biggest frog

The biggest frog in the world is the Goliath frog. It lives in West Africa and can measure more than a foot in length and weigh more than 7 pounds – as much as a newborn baby.


4.DARWIN'S FROG

\

When Darwin’s frog tadpoles hatch, a male frog swallows the tadpoles. He keeps the tiny amphibians in his vocal sac for about 60 days to allow them to grow. He then proceeds to cough up tiny, fully formed frogs.

5. Surinam toad

The female Surinam toad lays up to 100 eggs, which are then distributed over her back. Her skin swells around the eggs until they become embedded in a honeycomb-like structure. After 12 to 20 weeks, fully formed young toads emerge by pushing out through the membrane covering the toad’s back.

5 fun facts about monkeys 

1.OLD VS NEW

OLD WORLD MONKEYS

NEW WORLD MONKEYS

Monkeys can be divided into two groups, Old World monkeys that live in Africa and Asia, and New World monkeys that live in South America.

2.The smart one

Capuchin monkeys are believed to be one of the smartest New World monkey species. They have the ability to use tools, learn new skills and show various signs of self-awareness.

3.The noisy monkey

Howler monkeys are the loudest monkeys. Their howls can be heard for about two miles in the forest and almost three miles in an open area.

4.The smallest monkey

The Pygmy Marmoset is the world’s smallest monkey. It measures 117-159 millimeters (four and a half to six inches) in length and weighs 85 to 140 grams (three to five ounces).

5.The largest monkey

The male Mandrill is the largest monkey. It is almost 1 meter (3.3 feet) long and weighs about 35 kilograms (77 pounds).

5 fun facts about rabbits 

1. The average lifespan of a domesticated rabbit is around 5 to 8 years.

Spayed or neutered house rabbits generally live 8 to 12 years. According to the Guiness Book of World Records, the oldest rabbit in the world lived to the age of 18. Larger rabbits generally have shorter lifespans than dwarf rabbits.

2.Rabbits can jump up to 36 inches or higher.

Rabbits can jump vertically about 2 feet, but they can also leap 9 feet horizontally due to their robust back legs. Rabbits can balance on those powerful legs to scout their surroundings for predators, and they thump the ground vigorously to alert other rabbits of danger

3.Believe it or not, a rabbit’s teeth never stop growing throughout its life.

Like humans, rabbits’ nails grow constantly and need a trim about every six weeks. Unlike humans, rabbits’ teethgrow constantly! This makes it imperative that your rabbit gets unlimited timothy hay and wooden toys to chew on. If your rabbit’s teeth stop grinding normally, he or she may find eating painful and starve. Be sure to monitor your rabbit’s eating habits. Even 12 hours without food can be deadly.

4.Rabbits eat their droppings

It took me years to find out that rabbits need to digest twice. Healthy buns eat soft cecotropes directly from their … you know, so some rabbit guardians never see these. The hard round pellets that you see are the second round of elimination.

5.Rabbits get bored.

Just like humans, rabbits need socialization, space to exercise and plenty of toys to keep themselves entertained. I recommend stuffing a paper towel roll or cardboard oatmeal canister with timothy hay so that your bunny can roll, chew and play to his or her heart’s delight.

5 FUN FACTS ABOUT CATS

1.A CAT'S BRAIN IS MORE COMPLEX THAN A DOG'S.

Sure, their brains are small, accounting for just 0.9 percent of their body mass. But according to Psychology Today, "the brains of cats have an amazing surface folding and a structure that is about 90 percent similar to ours." The cerebral cortex—the part of the brain that's responsible for cognitive information processing—is more complex in cats than in dogs, and cats have some 300 million neurons, as compared to 160 million in dogs. Some research does suggest that dogs are slightly smarter than cats, but cat owners might have a different opinion on that. One more fun cat brain fact: The most sophisticated supercomputer in 2010 performed 83 times slower than a cat’s brain.

2.SOME OF THEIR ILLNESSES ARE SIMILAR TO OURS.

Cats are susceptible to more than 250 hereditary disorders, and many of them are similar to diseases that humans get. A genetic defect in a cat's DNA can cause retinitis pigmentosa, a disease that also affects 1 in 3500 Americans, and Feline Immunodeficiency Virus is a genetic relative of HIV. Felines even have their own form of Alzheimer’s Disease, and, like us, they can get fat—in fact, 55 percent (approximately 47 million) of American cats are overweight or obese.

3.CAT DOMESTICATION BEGAN IN CHINA.

Scientists once believed that cats were domesticated in Ancient Egypt approximately 4000 years ago, but new research, published in 2013, shows that a breed of once-wild cats lived in close proximity to farmers in China some 5300 years ago. "Our data suggest that cats were attracted to ancient farming villages by small animals, such as rodents that were living on the grain that the farmers grew, ate and stored," says Fiona Marshall, study co-author and archaeology professor at Washington University in St. Louis. "Results of this study show that the village of Quanhucun was a source of food for the cats 5300 years ago, and the relationship between humans and cats was commensal, or advantageous for the cats. Even if these cats were not yet domesticated, our evidence confirms that they lived in close proximity to farmers, and that the relationship had mutual benefits."

4.THEY REALLY CAN’T TASTE SWEET THINGS.

Cats aren't interested in sweet stuff because of a defect in the gene that codes for part of the mammalian sweet taste receptor. The receptor contains two protein subunits, T1R2 and T1R3, which are each coded for by a separate gene. The defect occurs on the T1R2 protein in domestic cats, as well as in cheetahs and tigers.

5.CATS SPEND A LOT OF TIME GROOMING.

OK, that fact on its own isn't very surprising. But just how much time cats spending grooming is. According to Cornell University's College of Veterinary Medicine, cats spend between 30 and 50 percent of their days cleaning themselves.

Self-cleaning has a number of benefits: It helps cool cats off, comforts them, stimulates circulation, and keeps them clean of odors that might attract predators. Sometimes, your cat might even groom you—that's her way of showing affection and marking you as one of her family group. Enjoy it!

5 fun facts about dogs

1.The "smell" center of a dog's brain is 40 times larger than        yours.

Dogs can smell thousands of times better than humans. Their noses have millions more scent receptors—for example, a human nose averages 5 million while a Dachshund's has 125 million—making them useful in sniffing out drugs, dead bodies, bed bugs, explosives, and more.

2.Tail wagging has its own language.

If your dog excitedly wags their tail, it means they're happy to see you, right? Not necessarily. According to Discovery.com, dogs wag their tails to the right when they're happy and to the left when they're frightened. Wagging low means they're insecure; and rapid tail wagging accompanied by tense muscles or dilated pupils can signal aggression.

3.Puppies are born blind and deaf.

Newborn dogs are still developing, according to Psychology Today, so their ear canals and eyes are still closed. Most puppies open their eyes and respond to noises after about two weeks.

4.Dogs have a "sixth sense."

In a 2010 poll, 67 percent of pet owners reported their pets acting strangely right before a storm, and 43 percent said their pets behaved oddly right before something bad happened. The top clues? Whining, erratic behavior, or trying to hide in a safe place. There are even reports that dogs can sense illnesses, like cancer.

5.Dogs dream like people.

If you've ever noticed your pooch twitching in her sleep, this probably means she's dreaming. Researchers found that dogs have similar sleep patterns and brain activity as humans, and that small breeds tend to dream more than large ones. Psychology Today suggests they're probably imagining familiar activities like playing outside or chasing their tail.
