Insects evolved around 480 million years ago, around the same time as the earliest land plants. Today, they represent more than 90 percent of the animal life forms on Earth. They are in many different body shapes and sizes. Here are the top 10 largest insects in the world.
Alligators are very large reptiles. An alligator is also a crocodilian – they are close cousins of crocodiles. But, unlike crocodiles – which can be found on all continents except Europe and Antarctica, they are native to only the United States and China. Here are 20 amazing alligator facts.
According to biology professor Alvin Silverstein’s 1980 book Nature’s Champions, in 1883, a giant saltwater crocodile bigger than Lolong was killed in the Philippines. It measured 27 feet (8.23 meters) from the tips of its snout to the end of its tail. It was also more than 2 tons in weight. Sources say it required the help of 40 men to bring its body ashore. And, when the massive crocodile was opened up for examination, individuals were taken aback to find the segmented remains of a horse, carved into seven distinct pieces.
There’s no photo of the crocodile, because of the record’s date, but if that story is true, it was the largest crocodile ever recorded.
Polar bears, Kodiak bears, Grizzly bears, and Kamchatka brown bears are among the largest bear species in the world. But, which one is the biggest bear in the world?
Everyone knows at least a little about dogs, or they at least know they love them. But there’s probably a lot you don’t know about man’s best friend, including where that phrase comes from!
Kodiak bear (Ursus arctos middendorffi) is a subspecies of brown bear (Ursus arctos). They inhabit the islands of the Kodiak Archipelago in southwest Alaska. They look like grizzly bears, however, they are significantly larger. Here are 15 amazing Kodiak bear facts.
Sloths are sluggish tree-dweller mammals of the rainforests of Central and South America. They are famous for their languid movements. Sloths spend most of their time hanging upside down in the tree branches and munching on leaves, twigs, and buds.
Identifying the largest dinosaurs ever lived isn’t an easy task, because it’s very rare to unearth a complete fossil. Furthermore, only a tiny percentage of these amazing animals were ever fossilized, and most of these “lucky” bodies will remain buried underground forever. So, we may never know exactly what dinosaur was the biggest (or the tiniest) ever.
Despite this fact, size always has been one of the most interesting aspects of these prehistoric animals. There are extreme variations in their size, from the tiny hummingbirds, which can weigh as little as three grams, to the titanosaurs, which could weigh as much as 70 tonnes, or even more.
Here are the largest dinosaurs ever lived.
Everybody knows most life came from the water, but how did it start? And how did it get where it is now?
In this article, we cover approximately 200 million years of fish evolution, from the first pre-vertebral filter feeders to the first tetrapod walking on land to the development of modern sharks – and everything in between.
On July 5, 1996, a female sheep named Dolly, the first mammal to be cloned from an adult cell was born. Scientists from the Roslin Institute (an animal sciences research institute at Easter Bush, Midlothian, Scotland) in Scotland successfully cloned Dolly using the process of nuclear transfer from a cell taken from a mammary gland.
