I know why rabbits have long ears but i don't know the answer to why they have long hind legs the answer to you first part of the question is.
Rabbits have long ears so they can detect noises or up coming danger. it also helps the rabbit cool itself down.
They do that for many reasons:
It's instinct. In case their foot pads are dirty.
Rabbits want to observe you when you pet them. You are a lot bigger than they are, and herbivores are not the most trusting creatures.
im not sure about shaking hands because rabbits dont like being held onto by their hands or legs. but you can certainly teach bunny some other tricks that are more natural for bunny like 'sit up!' (making bunny sit up on his hind legs). my bunny can do this
yes they do.if you take a string and dangle it above them they will stand up on their hind legs and get it.if they are trained then you don't have to hang a string all you do is tell them. that's for all i know :)
with there legs and paws they jump up or forward
Horse bucks are when the horse lifts its hind legs up very fast.
Ground sloths could stand up on their hind legs, but the walked on all fours. They would have had a slow, shuffling or swaggering gait because most species their walked on their knuckles or on the sides of their feet.
Yes, they can stand up on their hind legs and crawl on all fours.
yes, rabbits can back up but mostly they just stand on there hind legs and swivel around.
Not on their hind legs, no. They can stand (though for short periods at a time) on their four stout but short legs.
To say hi, my pet Hotot will usually nod his head up and down and sniff. Sometimes he will stand high on his hind legs and look up at you. Whenever my Hotot meets someone new that's what he does!
On her hind legs, or when she's sitting up, my female "dwarf lion-head" stands up to 1 foot and a half.
mainly birds and other meerkat groups that's why they have sentries the 1s that stand up on there hind legs
Rabbits are prey animals, and their only real defense against predation is their hind legs: rabbits run really, really fast. Unless caught off-guard, rabbits can out-run many animals: that's what their powerful hind legs are for. If they are caught off-guard, rabbits can execute amazing acrobatic twists in mid-air so they can change direction and run away from the predator: their powerful hind legs help with that, too. Lastly, when rabbits fight one another (usually, two males fighting for a female), they can hurt each other a little with their teeth, but really it's the powerful hind legs that are their weapons: rabbits disembowel each other!! The problem is, rabbits have such strong hind legs, that if you pick them up or handle them wrong, and they panic and kick into the air, they can break their own backs! That's why you must be very careful with rabbits.
Sometimes bears do this to warn their prey and sometimes they do it just to look at what lies ahead.
Iguanodon probably walked on all fours most of the time. To get a better view or reach food that was high up, they could stand on their hind legs. They may have also run on their hind legs when they were in danger.
They aren't designed to do it, if you'll take a horse and look at the way it walks, you'll see that it is reversed from us, to stand on their hind legs is like standing on our hands
Maybe, it could probably stand on its to legs only if it built up its muscle. There was a dog who could stand on its two hind legs, so maybe a panda could too.
A tiger regularly grows up to 11 feet in body length, so if it were to stand on its hind legs yes.
