1. Elephants can run up to 25 miles per hour. However, they remain the only mammal on earth that can't jump. They always keep one leg on the ground - even when running.
Why elephants are the only mammals that can't jump.
Giraffes aren't able to jump because they never need to jump and are too heavy for their thin legs to lift off of the ground. These lanky mammals are capable of growing 14 to 18 feet tall. The world's tallest animal can weigh anywhere from 1,500 pounds to 3,000 pounds.
Sloths can't jump, they can't see very far away and they move slowly and deliberately. Each step uses up valuable calories that they can't afford to waste. Wild sloths have survived for millions of years by being VERY good at efficient movements through the trees.
Hippos usually trot to move quickly on land and can gallop at 30 km/h (19 mph) when needed. They are incapable of jumping but can walk up steep banks.
Unlike most mammals, the bones in elephant legs are all pointed downwards, which means they don't have the "spring" required to push off the ground.
Mind Blowing Facts
Hop To It A kangaroo can't jump unless its tail is touching the ground.
Frogs use their long powerful legs to jump and hop around. Toads actually prefer to walk rather than hop. If they do jump/hop, they only move short distances. As such, they don't really need long legs like a frog does so their legs are relatively short.
Fun fact: Humans are believed to be the only animals that can blush. That's because embarrassment is a complicated emotion requiring understanding others' opinions and other factors.
Rabbits, bharals, hares, kangaroos, and klipspringer are among the animals that hop.
Octopuses have blue blood, three hearts and a doughnut-shaped brain. But these aren't even the most unusual things about them! Known for their otherworldly look and remarkable intelligence, octopuses continue to reveal astonishing qualities, abilities and behaviour.
And don't forget, kangaroos can't jump backwards!
The answer is... Elephants! Elephants are the only animal to have four forward-facing knees. All other four-legged animals have at least one pair of legs with knees that face backwards.
Though surefooted, camels can trip and fall and, like horses, camels can spook. Camels can bite, kick, regurgitate their cud (spit), jump, lay down or get up without warning.
In an elephant vs hippo fight, the elephant is going to win. Assuming both creatures are fully grown adults, the elephant is just too big for the hippo to handle. Hippos are too smart to pick a fight with an elephant, so they have no idea what it takes to bring one down.
You can't outrun a hippo, but you must get out of their space. If the hippo gets ahold of you, the odds of surviving are slim. That's why the best thing you can do is get as far away as possible. So, when a hippo charges you, don't stop moving until you're somewhere safe.
Although their bulk and toothy armoury usually ensure that they do not become victims of nocturnal hunters, even hippos fall prey to lions on occasion.
Answer and Explanation: A human cannot outrun a hippo. Hippos can run faster than 30 miles per hour, whereas the fastest human, Usain Bolt, has only clocked in at 23.4 miles per hour. Although usually slow on land, hippos are extremely aggressive, particularly if you get between them and the water.
Rhinos, hippos, and sloths are often mentioned as other examples of mammals that aren't able to jump, though rhinos and hippos can lift all four feet off the ground while running.
Kangaroos use body adaptations such as enlarged hind feet and a strong tail to help them hop. These adaptations allow some species of kangaroo, such as red and grey kangaroos, to efficiently hop 10 feet vertically, 40 feet horizontally, and reach speeds of over 30mph.
Lions and tigers can jump almost equally high. The vertical leap record for a tiger is more than 12 feet, and the lion is just a few inches less.
