Honey badger

The honey badger mostly eats meat, and does not have many predators because of its thick skin and tough defensive ability.  The skin around the neck is 6 millimetres thick, an adaptation to fighting each other. Their skin is almost proof against arrows and spears.

Honey badgers are fearless and tough animals. They are known to savagely attack their enemies when they cannot escape. They are tireless in combat and can wear out much larger animals in fights.  They kill and eat snakes, even highly venomous or large ones.
