Either a nerve got pinched from being overworked, or something else has caused paralysis of the hind legs in the animal. Better get him checked out by a vet.
No, only male platypuses have spurs on their hind legs. Young females do have them, but lose the spur by about the age of ten months.
Some are born without hind legs. They are also known to eat their own legs to avoid starvation when food isn't plentiful.
Sometimes in small animals, arthritis causes their bones to degenerate, and break down. I had a small dog once that had this problem, and while he was hobbling around, fell. It wasn't a big fall, but was enough to paralize him because it caused spinal cord damage. He lost the use of his legs, and control of his bowels and bladder.
Not naturally. Dogs can be born without legs or lose them through an accident. There is a video on You Tube of a dog that only has it's hind legs and it walks upright.
they stand on their hind legs and they spray or if you want a name they pee on their enemies.they also lose fur when bitten.
Humans normally have two legs, unless by a defect at birth or an accident along the lines of his or her life that causes him or her to lose a leg
Cancer is the disorder that causes someone's own cells in their body to lose the ability to control growth.
They lose their tails, not legs.
You can lose leg fat by swimming because the resistance of the water causes you to burn fat in your legs. Swimming is a good way to develop muscle and lose weight.
The male platypus has a venomous spur, not "poisonous claw", on each of its hind legs. Young females also have the spur, but it is not venomous and they lose it by about the age of ten months.
From my expirience with crickets (growing up with 2 brothers and playing with inocent little insects) they live about 5 minutes after the hind legs are removed. i highly recommend not conducting an expiriment to prove me right or wrong; can you imagine how painful that must be? But it also depends on the size of the cricket. the smaller ones die sooner than the larger ones, and the larger ones try to escape with their front legs. answering this question brings back memories....
