Why do crabs self amputate?
Many crabs, insects and spiders can break off a limb at a precise weak spot on their limb. Leaf-footed cactus bugs self-amputate not only to escape predators, but to shed injured appendages that might otherwise hinder their movement. These unique self-amputation behaviours have inspired engineers.
Do crabs amputate themselves?

What animal has eyes but Cannot see?
The octopus eye is technically color-blind. So is the eye of the cuttlefish, a related mollusk.

A uniped (from Latin uni- “one” and ped- “foot”) is a person or creature with only one foot and one leg, as contrasted with a biped (two legs) and a quadruped (four legs).

Can a four legged animal survive a leg amputation?
“Most [tripods] can reproduce, raise their young, and survive just as well as a four-legged animal.” Unlike humans, who can take years to recover from the loss of a leg, animals bounce back with surprising speed. Last summer, veterinarians at the Denver Zoo had to amputate a rear leg on one of their newborn African wild dogs.
Are there any prosthetic limbs for heavy animals?
Outside the country, apart from dogs, nothing has ever been done for heavy animals like cows (there was one remarkable story of an elephant getting an artificial limb in Thailand though). Until now, Dr. Tapesh was making prosthetic limbs for below-knee amputee animals.

This is because most three-legged animals can balance beautifully without a fourth leg, artificial or otherwise.
