Snake eating on frog limbs
Asian cookery snakes use their nephlic teeth Cut into the abdominal cavity of the toads And keep their limbs tumbling down, not empty skin pouches. Snakes sometimes spend hours gorging on frog inland areas; In particular, scientists caught snakes called venomous toads Dattaphrinus melanocyticus, Also known as Asian common toads or Asian black-spotted toads. Todders secrete a poisonous white substance, so scientists suspect that the dog snakes may have adopted their sinful dietary strategy to avoid this poison.
Cannibal monkeys
White-faced Poon monkeys (Sebus imitator) With their deep deep brown eyes and small faces with white faces, looks absolutely beloved – but sometimes, these lovely creatures will Their own kinship homogeneous. When an infant monkey fell from a tree in Costa Rica’s Santa Rosa National Park, relatives gathered around the corpse. Soon, a young man and a pregnant woman began to tremble at the baby’s legs and feet. In the end, they left only the head, chest, and arms. When hunting prey animals, the cappuccino usually consumes the whole animal as a sitting and group, with only two monkeys eating part of it; Because of this, scientists suspect that cannibalism may be an unusual behavior for white-faced cappuccinos.
Panda was caught on courtship camera
After three years of panda trekking through China’s Qingling Mountains, filmmakers caught two male bears To attract a woman’s attention. This wedding behavior is captured on film for the first time, and if you expect something beautiful and strict you will be mistaken.

Both males kept the females behind for several weeks, eventually, the younger males won.

Penguin Pop Bomb
Penguins can Shoot their pups Distances twice their body length and scientists calculated how much pressure they needed to do so. The team specifically looked at the Humboldt Penguins (Spheniscus humboldati), Which connects their feces with their structures in an impressive arc over their high ground. They calculated that the pressure produced in the penguin’s rectum was about 4 pounds per square inch (approximately 28.2 kilop als). This means that powerful poppers can soak their feces at about 5 miles per hour (8 km / h) and about 53 inches (134 centimeters).
The ‘Godzilla’ wasp lays its eggs in underwater caterpillars
This Microgaster Godzilla Wasp Earned his monster name The way it hunts hosts. The parasitic wasp dives underwater to catch moth caterpillars, which float below the surface in homemade casings. One-by-one wasp wrestles caterpillars out of their shells, taking them over the water and quickly pumping them full of eggs. The way the wasp erupts from the water is reminiscent of Godzilla scientists emerging from the sea in classic science fiction movies.
Brave (and gross) escape of E.L.
A blue heron was flying over the Delaware shoreline, when suddenly, a The American el came out of his gut. In a photo taken by Mary Davis engineer Sam Davis, the bird can be seen wrapping up like a fat fat necktie. After escaping from the belly of the blue heron, the brave surv eel may survive – but it can only come in or near water that was salty enough. Despite this gut-ranching encounter, the heron probably flew the next day.
Naked mole rats use carbon dioxide to avoid attacks
Naked mole rats survive in crowded underground burrows with little oxygen, but this is no problem for wrinkled weeds. Really naked mole rats, depending on oxygen More dependent on carbon dioxide; Without it, their brains would be short-circuited and shock the critics. Due to a genetic mutation, mole rats lack a switch in their brain that normally allows electrical activity. This change allows animals to store valuable energy stores and thanks to the high levels of carbon dioxide in their burrows, will suppress brain activity differently, which usually protects mole rats from attack.
Lemurs flirt using a dose of fragrant love liquid otion.
Male ring-tail lemurs (Lamar Cat) Produce their own colon Draw their tails with fluid from a gland in their wrists and during breeding. These wrist discharges often take on a bitter and leathery odor throughout the year, but when it comes to breeding, the colon takes on a sweet, fruity scent. Scientists have theorized that fluctuations in testosterone can lead to this change in odor, and may signal this when a man is ready for intercourse. But while women show a keen interest in mating-season tunic scents, it’s not clear if this smelly form of flirting really makes men more desirable partners.
Platypus glow under UV light
When scientists were studying old platypus specimens, they made a surprising discovery: UV, Usually brown creatures Leave the blue-green glow. Except Platypus, Flying squirrels and oss foss sums are the only other mammals known to display this type of biofluorescence. Scientists discovered this glow after studying flying squirrels at the Field Museum in Chicago, when they decided to train their black lights on duckbilled mammals as well, as both animals hunt during twilight and night. The green luster of the platypus may reduce their visibility for predators, the team assumes, but more research is needed to confirm that theory.
Mantis steals shrimp from rival’s house
Mantis shrimp Neogonodactylus bradini Wear club-like weapons, which they use Give the little shrimp a bump outside their house. Crustaceans, known as “smashers”, can rotate their arms at speeds of up to 50 mL (80 km / h) and take them out on coral burrows in the South Caribbean Sea. In a laboratory study, scientists found that, if given a choice between empty burrows, shrimp prefer large, spacious rooms in which they can grow. But when other shrimp take home in burrows, smashers attack shrimp the most in small bruises. Although the burrow may be a tight squeeze, the attacking shrimp probably knows the occupant will be smaller and therefore easier to beat, the researchers suggested.
