It protects itself
Flaps of featherless skin between their front and back legs helps it fly better and faster
they spray their ink sack
a tiger salamander protects itself by poisoning its prey.
the eye lashes protects the eye from on coming objects
it protects itself by being on a high tree or being in a herd with its friends and relatives.
a falcon protects itself with its claws and beak.
what do you mean a puffing
by it's thorns
it bites its enemy
It doesn't.
