Fastest Animal on Land: Cheetah Aconyx jubatusCheetahs are, without a doubt, the fastest creatures in the world on land. (There's probably some wickedly fast creatures in the ocean that we still don't even know about). Why would a cheetah need to be able to run so fast? The only ...
The fastest-flying animal on record is not a bird but a mammal. A 2016 study published in the journal Royal Society Open Science clocked Brazilian free-tailed bats (Tadarida brasiliensis) flying up to 44.5 meters per second, or 100 mph (160 km/h). The study tracked female bats that ...
As you know, cheetah, the fastest-running animal on land, can gain a top speed of 75 mph. The strong, long legs help cheetahs to gain this speed within seconds. Unlike other members of the big cats family, cheetahs are small and have a height of 3 feet. Cheetahs are native to Africa...
that speed, they spend more time in the air than on the ground.The largest animal in the world is the blue whale.Here's an interesting fact about these largest animals.They aren't just the largest species (物种) right now.They are the largest animals that have ever existed on Earth. ...
OK, world's fastest animal, world's fastest person — these are all fine and good, but with a serious Earth-centric bent. Indeed, there are many things in our universe that makeEarth seem like a poky planet. Considering that a year in our world consists of 365 interminable days, it mi...

The wind conditions of Southern ocean have a huge influence on the flight speed of grey headed albatross. They take advantage of strong Antarctic storms to fly faster. In such conditions, the large wingspan of the grey headed albatross also helps them to make a well balanced flight. ...
For example, previous research suggested that the megalodon may have taken bites of sperm whales' faces rather than eating the entire animal. However, it is unlikely that the megalodon would have to eat such large meals very often. Based on its size and swimming speed, the researchers ...
drains the Greenland ice sheet into a deep ocean fjord on the coast of the island. At its calving front, where the glacier effectively ends as it breaks off into icebergs, some of the ice melts while the rest is pushed out, floating into the ocean. Both of these processes contribute abo...
Compressed ultrafast photography (CUP) was a good starting point. At 100 billion frames per second, this method approached, but did not meet, the specifications required to integrate femtosecond lasers. To improve on the concept, the new T-CUP system was developed based on a femtosecond streak ...
