Why can’t limbs grow back?

Do alligator arms grow back?
No. While some lizards can regrow their tails (not all of them can), none can regrow their limbs. Other types of reptiles (turtles, crocodilians, birds) can’t regrow anything at all. An alligator that has its leg bitten off must go through life without its leg.

Can spiders grow new legs?
Spiders can regrow any one of their eight legs if they happen to lose one. In order for a spider to grow they have to shed the skin of their hard outer shell called an exoskeleton. This is also known as molting. It’s during this molting that they can regrow a missing leg!
Can a spider survive with 7 legs?
Spiders can live without one or two, and even three of their legs. It can make life more difficult for them, but they’ll be alright.

Why dont flies die when you hit them?
First, flies, like all arthropods, have exoskeletons which protect them. If you aren’t “squishing” them, crushing the exoskeleton, you aren’t going to kill them. In other words, you need to hit them harder. But really, you can’t produce enough velocity with your arm/hand to fatally swat a fly out of the air.
