Ants function as part of a colony, and when one of these guys believes his time is up, he takes one for the home team. These ants produce a toxin that can harm their attackers, and they can cause their bodies to implode to release that toxin in an explosive blast.
The Cuttlefish can illuminate its body with vibrant, scintillating colors. It uses the flashing lights and psychedelic patterns to hypnotize prey and ward off would-be attackers.
The sleek, slender stick insects effectively use camouflage to protect themselves. If they are located and injured by an attacker, they may come away hurt by the encounter. But not to worry; they can regenerate lost limbs if needed.
The Electric eel is named because of its ability to generate an electric shock as a defense mechanism. Potential predators won't mess with this bad boy more than once!
The Motyxia Sequoiae is an odd looking creature, even when not feeling threatened. When a predator does approach, it gives a warning by glowing. If that doesn't deter the attacker, the toxins it can release should do the trick.

The softshell turtle spends 95% of its life buried in sand with only its eyes visible. While it doesn't have the hard shell of its relatives for protection, its expertise at hiding makes up for the difference.
In the Southern United States, everyone has heard the phrase, "playing 'possum". This is a reference to the practice of the native opossums of "playing dead" when threatened. The opossum will feign death, lying limp and apparently lifeless, in the hopes that the threatening predator will go away.
When the Eurasian Roller bird feels threatened, it will make itself throw up. The bright orange liquid gives off a horrendous odor, repelling the would-be attacker.
