In the wildlife kingdom, predation is central to survival and reproduction, but certain behaviors and strategies can be particularly brutal and intriguing.
The spotted hyena (Crocuta crocuta), a predator widely distributed in Africa, is known for its unique and efficient hunting strategy. What is particularly chilling is their "anus-picking" attack. So, what are the biological and ecological factors behind this behavior? Why do animals that have their ans removed tend to stay still? This article will explore this phenomenon from the aspects of behavior, ecology and neurobiology and reveal its mysteries.
The hunting strategy of the spotted hyena
The spotted hyena is a highly social animal that lives in groups of dozens of members. These groups are tightly organized and have a clear hierarchy. The way spotted hyenas hunt depends not only on the strength and speed of the individual, but more importantly on the cooperation of the group. In contrast, solo predators are much less successful and efficient in hunting.
Anal plucking (i.e., attacking the anal area of the prey) is a common and highly effective strategy in the hunting behavior of spotted hyenas. This strategy takes advantage of the vulnerability of the prey's abdomen and the response of the nervous system. By attacking the anal area, spotted hyenas are able to quickly kill or render their prey incapacitated. This strategy not only reduces the likelihood of prey escaping, but also minimizes the risk of injury to spotted hyenas during the hunt.
Why do animals stay still when their anuses are removed?
When a spotted hyena attacks the anal area of its prey, it triggers the prey's nervous system, causing it to experience a "freezing response". This response is an instinct of the brain when faced with extreme fear or trauma, and this mechanism can be traced back to the evolutionary history of animals. The freezing response is a defense mechanism that is often used to avoid the attention of predators. However, in this case, it becomes the Achilles heel of its prey.
From the point of view of evolutionary biology, the freezing reaction is a kind of "last line of defense". When faced with inevitable predation, many animals opt for this strategy in the expectation that the predator may abandon the predator due to loss of interest or other reasons. However, spotted hyenas seem to have evolved a strategy specifically to counter this defense mechanism. They take advantage of the freeze reaction to deliver a lethal attack with ease.
The anal area is one of the more fragile and sensitive parts of the body in many animals, as it concentrates a large number of nerve endings and blood vessels. Attacking this area not only quickly causes the prey to lose too much blood, but also causes severe pain in the prey through nerve conduction, further reinforcing the freezing response. This physiological vulnerability makes the spotted hyena's anal plucking strategy particularly effective.
Anal plucking strategy
In nature, the relationship between predator and prey is often likened to an "arms race", with both sides constantly evolving new and counter-tactics. The spotted hyena's anal plucking strategy is part of this race. Prey must constantly improve their escape and defense strategies, while spotted hyenas are constantly refining their hunting methods to maintain a dynamic balance in the ecosystem.
The hunting behavior of spotted hyenas not only affects the number and population structure of prey, but also has a profound impact on the entire ecosystem. By controlling prey populations, spotted hyenas maintain the health of herbivore populations to some extent, preventing overgrazing and vegetation destruction. This ecological balance contributes to the maintenance of diverse biomes and the stability of ecosystems.

Understanding the hunting behavior of spotted hyenas and the defense mechanisms of prey will not only help us better protect these species, but also provide new ideas for wildlife conservation strategies. For example, when designing protected areas, consideration can be given to how to reduce the occurrence of anal plucking to improve the survival rate and population stability of prey.
The spotted hyena's anal plucking strategy and the freezing response of its prey also make us reflect on certain behavioral patterns in human society. In the face of extreme stress and fear, humans often experience a similar "freeze reaction". Understanding these instinctive responses and the neural mechanisms behind them may provide new perspectives for psychological and sociological research.
The act of stripping out the anus of the spotted hyena is not just a brutal scene in the wildlife world, it has a rich biological and ecological significance behind it. By delving deeper into this phenomenon, we will not only be able to better understand the complex relationship between predators and prey, but also draw useful insights from them to advance wildlife conservation and related research. Despite the brutality and competition in nature, it is these phenomena that give us a glimpse into the diversity and adaptability of life. It is hoped that readers will benefit from this article, not only to gain a deeper understanding of the behavior of spotted hyenas, but also to stimulate more thinking about the natural world and their own behavior patterns.
