What bird can fly the highest? What bird can fly the fastest? What fish can swim the fastest? What sea mammal can dive the deepest? What animal can run the fastest? What animal can run for the longest distance? Etc.

I just know that the fastest animal on land is cheetah, and I am a new animal lover.

The deepest diving sea mammal is the sperm whale.

Peregrine Falcon is the fastest bird. The highest flying bird is probably the griffon vulture.

A whale’s nearly four-hour-long dive sets a new record www.sciencenewsforstudents.org/article/longest-record-dive-cuviers-beaked-whale To break the record for longest dive by a marine mammal, take a deep breath and jump in the water. Then don’t breathe in again for almost four hours. Cuvier’s beaked whales (Ziphius cavirostris) are master divers. These creatures hold the record for deepest plunge by a marine mammal. One whale dived to depths of nearly 3,000 meters (almost 1.9 miles). This species also holds the record for the longest dives. In 2014, scientists documented one dive that lasted just over two hours. That whale stayed underwater for 137.5 minutes, setting a record. Another Cuvier’s beaked whale has now shattered that record. It went 222 minutes, or three hours and 42 minutes, without coming up for air. Researchers reported this September 23 in the Journal of Experimental Biology. To last so long underwater, the mammals may rely on large stores of oxygen and a slow metabolism. Once oxygen runs out, the animals may have the ability to tolerate a buildup of lactic acid in their muscles due to anaerobic (An-eh-ROH-bik) respiration. This is a method of generating energy that doesn’t rely on oxygen. “These guys blow our expectations,” says Nicola Quick. She studies animal behavior at Duke University Marine Laboratory in Beaufort, N.C. To better understand how the whales manage such long dives, the scientists looked to seals. Also marine mammals, seals can spend a long time underwater, too. Researchers have studied the diving habits of seals in the past. They can use that knowledge to learn about other animals. The researchers did some math based on a seal’s oxygen stores and diving time limits. That hinted that underwater whales should run out of oxygen after only about half an hour. Quick’s team then analyzed 3,680 dives by 23 whales. Seals can exceed their limit about 5 percent of the time. The team assumed that was true for Cuvier’s beaked whales, too. While most whale dives lasted around an hour, 5 percent exceeded about 78 minutes. That suggests that switching to anaerobic respiration takes more than twice as long for whales as had been thought. The researchers expected to find that the whales spend more time at the surface recovering after long dives. However, the new team saw no clear pattern. “We know very little about [the whales] at all,” Quick says, “which is interesting and frustrating at once.”

Highest Flying Birds www.worldatlas.com/articles/highest-flying-birds.html 1. Rüppell's Griffon Vulture - 37,000 Feet The Ruppell's griffon vulture (Gyps rueppellii) is the highest flying bird in the world. This vulture species is found in the Sahel region of central Africa. Unfortunately, the Rüppell's griffon vulture is currently critically endangered with a population of 30,000. The population of this species is also steadily declining, and factors such as poisoning by elephant poachers and habitat destruction are the main threats to the survival of this species. This highest flying bird has been recorded to fly at an altitude of 11,300 meters (37,000 feet). They use their keen eyesight to scan the ground below from extreme heights and then once a meal is spotted, they swoop down to grab the prey.

A little calculation from my side; based on the table on Siberian tigers which was created by Guate Gojira a modern Siberian tiger weighs about 189kg on average and has a HB-length of 195cm over the curves which will equate to roughly 185cm straight line. Based on Blanchard's work on Yellowstone grizzlies a modern interior grizzly weighs about 193kg and has a HB-length of roughly 164cm measured in a straight line.
189/1.85³ = 31.27 (Siberian tiger) 193/1.64³ = 43.76 (Yellowstone grizzly)
When putting the weight in relation to the body length we can clearly see that the grizzly would be the much heavier animal per length. How heavy would a grizzly be when reaching a HB-length of 185cm just like the Siberian tiger?
x/1.85³ = 43.76 x = 277kg
A grizzly bear the same length as a Siberian tiger would weigh roughly 277kg; that's a full 88kg (195lbs) heavier and pretty close to the 100kg I'd have estimated from scratch. It shows that even at equal body weight a grizzly bear would be built like a short powerlifter and the big cat more or less like a tall and rather lean athlete which for me is enough evidence that at even at equal body weights a brown bear would have a bigger maximum strength output than a big cat also considering his superior limb morphology in terms of dexterity and grappling. I think Teddy Roosevelt would be agreeing with me too. Brown Bear vs Tiger is basically like a weight-lifter, wrestler, shot put, or hammer thrower ( bear ) vs a gymnast, high jumper, discus thrower, or boxer ( tiger ).
