A defence mechanism can become pathological when its persistent use leads to maladaptive behaviour such that the physical or mental health of the individual is adversely affected. Among the purposes of ego defence mechanisms is to protect the mind/self/ego from anxiety or to provide a refuge from a situation with which one cannot currently cope ...
The evolution of fortress defense is closely linked to the specialization of soldier mandibles. [12] Soldiers can have biting-crushing, biting-cutting, cutting, symmetrical snapping, and asymmetrical snapping mandibles. These mandibles may be paired with frontal gland secretion, although snapping soldiers rarely utilize chemical defenses. [12]
Anti-predator adaptations are mechanisms developed through evolution that assist prey organisms in their constant struggle against predators. Throughout the animal kingdom, adaptations have evolved for every stage of this struggle, namely by avoiding detection, warding off attack, fighting back, or escaping when caught.

The defense mechanisms animals use to evade or fight off predators can be both bizarre and fascinating. Some use camouflage or mimicry, while others have protective armor. Sea cucumbers, however ...
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
When you think of “gory” animals, creatures like great white sharks, tigers, and vampire bats might come to mind. But the most gruesome defense mechanism of any animal belongs to something ...
Bacteria (and perhaps other prokaryotic organisms), utilize a unique defense mechanism, called the restriction modification system to protect themselves from pathogens, such as bacteriophages. In this system, bacteria produce enzymes , called restriction endonucleases , that attack and destroy specific regions of the viral DNA of invading ...
