I would claim animals such as the wolverine and honey badger themselves are living biological weapons. They are basically designed to take and survive devastating attacks that would be fatal to just about any other animal (including us) and dish it back out several fold (they'll fight off and kill even apex predators such as lions and bears despite their small size). Their explosive tempers and ruthless aggression and add to their status as a living weapon, making them some very seriously dangerous animals.You would have to completely annihilate the entire planet and every form of life.
So the answer is no.
Human beings aren't the only ones that use weapons. Chimpanzees will use sticks as clubs to kill other creatures. I don't know exactly how many but its thousands of other animals have evolved weaponized body parts. Not just sharp claws/teeth either. But biological and chemical weapons, acids, poisons, venoms, harpoons, even sonic weapons (pistol shrimp).
It's just apart of life.
