The deadliest animal is the mosquito 

Forget lions, tigers and bears and even that tooth to torpedo the great white shark. For humans at least, the mosquito is the world’s deadliest animal. These small, bothersome miscreants are mini murder machines, killing around seven hundred twenty-five thousand people every year. That’s not because their bites are immediately deadly, of course, but because of the transmission of deadly diseases like malaria, dengue fever and several lightest and yellow fever.

The next deadliest animal to humans is, of course, humans who kill approximately four hundred seventy-five thousand people annually. Compare these numbers to shark fatalities, which average around 10 a year.

Tardigrades can survive in space

 Tardigrades, also known as water bears, are the adorable eight-legged survivors of the microscopic world. These teeny tacts pods may look plump and cumbersome but they’re so hearty, they’re practically indestructible in subzero temperatures, they can dehydrate to just 3 per cent water and wait out the cold for up to five years.

They can survive with no access to food or water for 30 years and even survive the solar radiation and vacuum of space. A fact that some astrobiologists have evoked to support the plausibility of panspermia, the hypothesis that life arrived on Earth from other planets.

The Portuguese man o’ war is legion

 It’s the Voltron of the Marine World where the mega Zord if that’s more your thing. The Portuguese man of war, also known as the floating terror, resembles a jellyfish but it’s something called a siphon for a colonial organism made up of smaller, specialized animals who together form the mighty gelatinous marvel you see before you called Zoids.

These smaller organisms live out their lives attached to their neighbours. Unlike Voltron, the robot lions, they’re unable to survive apart, while some form the nifty sail and air-filled bladder that allow it to water with the wind and currents. Others form venomous tentacles used to paralyze and kill unwary fish, interesting facts about animals.

Some turtles breathe through their butts

 This cute little turtle has a secret. He can breathe through its butthole or more accurately, its cloaca the multifunctional orifice used for urinary they just give and reproductive functions in amphibians, reptiles and birds. By collecting oxygen from water sucked in through its DERRI air, the Australian Fitzroy River turtle can accomplish 70 per cent of its oxygen uptake.

A few other species have also mastered the technique, interesting facts about animals. The North American Eastern Painted Turtle uses the same trick to survive hibernation in winter at the muddy bottom of creeks and ponds and turtles aren’t the only Bumbry others. Sea cucumbers and dragonfly nymphs can do it too.

The platypus has some weird anatomy 

The platypus is so bizarre. Scientists first thought it was a hoax. A furry Frankenstein put together by some mad taxidermist. As it turns out, the platypus is even stranger than it looks. Not only is it one of the only mammals besides the kidney that lays eggs, but the males are also venomous thanks to ankle spurs on their back feet. It’s been speculated that they’re used to fight off rival males during mating season but can also inflict painful injuries on unwary humans while not lethal.

The pain is reportedly excruciating, interesting facts about animals. Oh, and if that isn’t all weird enough, the platypus as bill consents electric fields.

Corals do it long distance

Long-distance relationships are tough. This is especially true for corals. Corals are colonies of tiny, genetically identical animals called polyps, which reproduce both asexually and sexually but finding a date is hard when you’re anchored to the ocean floor. So corals often spawn on the same night, releasing innumerable eggs and sperm into the water.

These gametes fuse to form larva called plentifully and most become quick snacks for hungry fish but a few of the kids make it settling down in a new location and becoming their self-sufficient colonies.

Migrating birds might see Earth’s magnetic field using quantum entanglement

 Bird migration has long puzzled biologists. Birds use Earth’s magnetic field to navigate thousands of miles between wintering and breeding grounds but scientists aren’t quite sure. How the magnetoreception of European robins is so sensitive. Researchers have argued that their internal compasses must rely on my nute effects at the quantum scale.

For now, it’s just a theory but biophysicists have proposed that the effects of the magnetic field on entangled electrons cause a biochemical reaction in avian eyes that allows birds to see Earth’s magnetic field, giving them a sort of heads up display that guides them around the world.

Animal blood isn’t always red

We associate blood with the colour red. We have blood moons and blood oranges and it’s true, the blood is red in many animals, thanks to the iron-rich haemoglobin in red blood cells though that’s only when it’s exposed to oxygen but in some animals, other proteins are responsible for carrying oxygen around the body. Octopus blood, which relies on a copper-containing protein called Hemo Sinon, is blue and the plasma that serves as insect blood is a yellowish-green colour.

The green-blooded skink of New Guinea, on the other hand, has yet you guessed it, green blood, thanks to toxic bile pigment that may protect it from parasites.

Zombie ants exist 

While zombie takeovers make for good horror movies they are purely fictional, right in the insect world. That isn’t necessarily true. A species of cordyceps fungi reproduce by infecting ants and taking control of their bodies after driving infected hosts to climb up plants dams. It explodes out of their heads, showering spores onto ants below and these aren’t the only zombie insects laid inside the abdomen of hapless spiders.

The larvae of a certain Costa Rican wasp secrete a hormone that forces their host to spin a web perfect for building their cocoons. Once they suck its body dry, maybe keep those zombie survivals plan in your back pocket just in case.

There are immortal jellyfish

Who wants to live forever? Is autopsies, Dannii the immortal jellyfish is one of several types of animals whose figured out how it’s essentially a real-life Benjamin Button able to age backwards and become young again. Once they reach maturity, they start life as free-swimming larvae, then bed down on the ocean floor as polyps. That bud tiny Maduekwe but when injured, they can also reverse this process back to being a polyp and repeated indefinitely, making them biologically immortal.

Some scientists think this nifty trick has enormous potential for regenerative medicine but don’t hold your breath waiting to see a Real-Life Fountain of Youth anytime soon.
