The toxins in milkweed plants are called cardiac glycosides. These chemicals are harmful to many animals if ingested, but monarch butterflies have evolved to tolerate them and even use them for defense against predators.
A.chemicals produced by plants that often repel parasites, and 1) have no known physiological function, 2) are not breakdown products of larger molecules, 3) are actively synthesized from smaller precursors, 4) often contain relatively rare components, 6) often are energetically expensive to produce, and 5) repel, injure, and/or kill parasites.
Some herbivores have evolved ways to hijack plant defenses to their own benefit, by sequestering these chemicals and using them to protect themselves from predators. Plant defenses against herbivores are generally not complete so plants also tend to evolve some tolerance to herbivory.
In the film "Predators," the main weapons used by the characters are firearms such as assault rifles, pistols, sniper rifles, and shotguns. Additionally, characters also use improvised weapons like machetes, spears, and explosives in their fight against the Predators.
Chemicals such as interferons, interleukins, and tumor necrosis factor are important in protecting the body against viruses and some forms of cancer. These chemicals help to activate the immune response, including stimulating the production of white blood cells and enhancing their ability to recognize and destroy infected or cancerous cells.
Pandas rely on vicious cuteness to subdue predators that attack them, their main defensive maneuver is cuddling.
They'll coil up into a defensive position and rattle their tail and will often strike out with their fangs .
It's defensive strategy against predators. Cattle are naturally herd animals, and when stressed or chased, they will cluster into a larger collective--being a herd--and move accordingly.
Millipedes escape from predators primarily through their ability to secrete toxic chemicals and noxious substances, which deter potential threats. Some species also employ a defensive behavior known as coiling, where they curl up to protect their vulnerable segments. Additionally, their hard exoskeleton offers some protection, and their slow, deliberate movements can make them less noticeable in their environment. These strategies collectively enhance their chances of survival against predation.

By biting the predators with their venomous fangs.
They use their horn to ward off predators.
Pith can serve as a defensive mechanism in plants by providing structural support and storage, which can deter herbivores. Its spongy texture can make it less palatable or more difficult for animals to consume. Additionally, some piths may contain secondary metabolites that can be toxic or unappealing to potential predators, further enhancing the plant's defense against herbivory.
Musk oxen are generally known for their calm and social behavior. They are herd animals that rely on group dynamics for protection against predators, displaying a strong sense of loyalty to their companions. Their temperament can be defensive, especially when they feel threatened, as they will form a defensive circle around their young. Overall, they exhibit a blend of gentle nature and protective instincts.
