Huge Python Swallowing an Antelope 2016

The first complete sequence of any snake genome reveals that Burmese pythons evolved rapidly to be able to eat prey as big as their own bodies. The python's amazing eating abilities derive from the genetic capacity to alter its metabolism and the size of its organs after a meal, according to a new study published today (Dec. 2) in the journal Proceedings of the National Academy of Sciences. Some organs more than double in size in the two days after a python, which averages about 12 feet (3.7 meters) long, eats. Eating isn't the only extreme snakes have gone to in their evolutionary history. To become the long, slithering creatures they are today, snakes have lost their limbs, reduced one of their lungs, elongated their skeletons and organs, developed a hinged jaw, and in many cases, evolved a toxic brew of venoms. They also rapidly fluctuate their metabolism based on their feast-or-famine diet of periodically swallowing large prey whole. [Photos: Giant Pythons Invade Everglades] Extreme evolution To understand this amazing evolution, University of Texas at Arlington biologist Todd Castoe and colleagues from four countries sequenced the genome of the Burmese python (Python molurus bivittatusI) and the king cobra (Ophiophagus hannah). By comparing the two, as well as snippets of the genomes of other reptiles, amphibians, birds and mammals, the researchers were able to track the evolution of the genes that make pythons such incredible eaters. "We'd like to know how the snake uses genes we all have to do things that no other vertebrates can do," Castoe said in a statement. The snake genome comparison enabled Castoe and his colleagues to track positive selection throughout the python's history. Positive selection is the evolutionary process by which useful traits — such as the python's unhinging jaws — are adopted by a species. In snakes, this process has been unusually rapid, the researchers found. "What we are seeing in snakes is unprecedented," study researcher David Pollock of the University of Colorado School of Medicine said in a statement. Genetic changes Snakes come by their extreme features through a combination of changes in DNA, changes in how DNA's instructions are carried out in the body, and changes in the reptile's proteins, the researchers found. The changes that occur in a python's body after feeding, for example, require the coordination of thousands of genes. Genes are the blueprints for the proteins that act as the building blocks of the body's tissues. The process of carrying out these genetic plans is called gene expression. After a python eats, its gene expression changes rapidly. Genes that may have been quiet suddenly come alive as their instructions are expressed. Some genes that are expressed steadily in daily life become more active, churning out massive amounts of proteins that promote growth or metabolism. Some of these genes are important for human disease. For example, a gene called GAB1, which appears altered in the python genome, is involved in some human cancers. "The Burmese python has an amazing physiology," Stephen Secor, a University of Alabama biologist and study co-author, said in a statement. "With its genome in hand, we can now explore the many untapped molecular mechanisms it uses to dramatically increase metabolic rate, to shut down acid production, to improve intestinal function, and to rapidly increase the size of its heart, intestine, pancreas, liver and kidneys. The benefits of these discoveries transcends to the treatment of metabolic diseases, ulcers, intestinal malabsorption, Crohn's disease, cardiac hypertrophy and the loss of organ performance."

Eagle vs Snake - Animal Fight Compilation 2016

Woodpecker is one of the most interesting types of birds. There are over 200 species of woodpeckers that can be found all around the globe except in Australia, New Zealand and Madagascar. Woodpeckers live in forests, backyards and various other types of habitat where trees are available. Several species of woodpeckers are endangered or already extinct due to habitat loss and increased urbanization. Also, chemical pollution and usage of aggressive pesticides negatively affects survival of woodpeckers in the wild because it induces destruction of the eggs. Interesting Woodpecker Facts: Size of woodpecker depends on the species. Largest woodpecker (great slaty woodpecker) can reach 20 inches in length. Smallest woodpeckers (the piculets) are usually 3 to 4 inches long. Woodpeckers are usually red, white, black and yellow in color. Their plumage can also be combination of orange, green, brown and golden color. Woodpeckers have very long tongue which is designed for capturing of prey that is hidden inside the trees. Certain species have barbed tongue. Woodpeckers are omnivores. They eat insects, insect larvae and eggs, tree sap, seed, nuts… Woodpeckers have chisel-like bill that is used for drilling of the trees when woodpecker searches for food or when it prepares nest during the mating season. Woodpecker is able to peck 20 times per second. It produces between 10,000 and 12,000 pecks per day. Although pecking of the trees looks like activity that may hurt woodpecker, bird does not feel the pain at all. Brain is prevented from trauma thanks to special air pockets in the scull. Both males and females are able to drum the trees. Since woodpeckers do not have vocal cords, this activity also play important role in communication. Feathers that look like bristles on the nostrils of woodpecker prevent inhalation of wood particles. Woodpeckers have zygodactil feet. Their feet have 4 fingers, two facing forward and two backward. This arrangement ensures strong grip to the branches and provides stability. Woodpeckers also have a pair of centrally located feathers that provide stability and keep them in the upright position while standing on the trees. Woodpeckers have unique flying pattern: three wing flaps are followed with gliding. This pattern repeats all the time during the flight. Woodpeckers build nesting holes in the trees all year round. Old holes often become home for other birds and mammals, such as starlings, chickadees, owls, and squirrels. Woodpeckers are monogamous (one pair mate for a lifetime). Both male and female prepare nest in the tree. Female lays between 2 and 5 eggs. Incubation period lasts 11 to 14 days. One month after hatching, young woodpeckers are ready to leave the nest. Depending on the species, woodpeckers can survive between 5 and 11 years in the wild.

Lions Chase and Kill Cape Buffalo 2016

There are only about 26,000 lions on the planet, and most of them live in Africa, south of the Sahara desert [source: National Geographic]. As with many species, the male lion is typically larger than its female counterpart. While a lioness is usually about 5 feet (1.5 meters) long and around 400 pounds (181.4 kilograms), males can be as long as 8 feet (2.4 meters) and tip the scales at 550 pounds (249.5 kilograms). The world's most social cats, lions live in groups called prides. Between three and 30 lions make a pride, which is comprised almost entirely of related females. This tightly knit group of lionesses will stick together for life -- it's quite difficult for an unrelated lone female to be accepted by the group. The males, on the other hand, generally move on after reaching adulthood -- nature's way of stirring the genetic pot. A pride may have up to two unrelated adult male lions, and these males are under near-constant assault from other males trying to move in on their territory. A male may hold its top spot in the pride for several years, but eventually he will be killed or run off by a younger or stronger outsider. If he isn't killed in the process, the usurped male must leave and become a loner, doing his best to survive alone or looking for another pride with a male he can conquer. It's good to be king, however. Lionesses do more than 90 percent of the hunting, while the male shows up after the kill, demanding and receiving first dibs on the meat. While the lionesses hunt, the males stay back to defend the territory, protect the cubs and keep watch for overly ambitious lone males who know a good situation when they see it. Lionesses are lighter, faster and more agile than males, and these traits make them deadly hunters. These killers hunt in packs to limit injury, often between dusk and dawn. The African buffalo hunts little more than grass, but you wouldn't want to bump into one in a dark alley. At 6 feet (1.83 meters) tall and 1,500 pounds (680.4 kilograms), this abundant and unpredictable creature is in no mood for monkey business (or lion or leopard business). Strong, powerful and wielding a set of horns that can measure 4 feet (1.22 meters) from tip to tip, the African buffalo isn't the kind of creature you want to startle. Many people consider them more dangerous than lions, and for good reason -- on average, more people are killed by African buffalo every year than by these big cats What they lack in speed, they make up for in stamina, and, like the lion, African buffalo are quite sociable with their own kind, often traveling in herds that range from 350 up to several thousand buffalo. As in prides, these herds consist overwhelmingly of females, and males use their giant horns to jostle for dominance. Male calves, which can walk at birth but are dependent on their mothers in the first year of life, must leave the herd once fully grown. Dominant male buffalo, which physically peak at about 10 years of age, must also leave once they've been conquered and replaced. These solo males, once the defenders of the entire herd, are now easy prey for lions in need of a big meal.
