Why Animals Are Less Likely to Get Stuck by Fish Bones
In nature, how do animals avoid getting stuck by fish bones? In fact, many animals face the risk of getting stuck by fish bones, but we rarely see them fail because the surviving animals continue to reproduce, while those that get stuck have already died. This article will reveal why animals are less likely to get stuck by fish bones compared to humans, and the clever strategies behind it from an evolutionary perspective!
Why Are Animals Less Likely to Get Stuck by Fish Bones?
At first glance, this may seem like a simple question, but it actually hides a lot of biological complexity. In the wild, animals often face the risk of fish bones and sharp fins when hunting fish. However, nature has its rules, and it tends to filter out the “failures.” Animals that get stuck by fish bones die, which reduces the frequency of these incidents.
The Difference Between Animals and Humans
Humans eat cooked fish, and the meat becomes loose after cooking, making it easier for bones to get stuck. In contrast, wild animals eat raw fish, where the fish bones are tightly wrapped in the meat and less likely to puncture the esophagus. Even if they do get stuck, animals can easily expel the bones through vomiting or other methods.
Evolutionary Strategies
Many animals have evolved specific strategies to deal with fish bones. For example, birds adjust the angle of the fish so that the fish head faces downward, swallowing quickly to avoid problems. In addition, birds have a special mucus membrane in their digestive tract that helps the fish bones pass smoothly into the stomach. Brown bears prefer to eat the fatty parts of fish, avoiding the bony sections, which naturally reduces the chances of getting stuck.
Nature's Harsh Selection
Despite their various strategies, animals still occasionally get stuck by fish bones. Some individuals get stuck and ultimately die from this danger. From the perspective of nature, individual deaths are insignificant. What matters is the survival of the species as a whole.
Conclusion
The differences between humans and animals when it comes to getting stuck by fish bones reflect two major evolutionary factors: bipedalism and cooking food. These seemingly small differences determine our vulnerability in facing the challenges of the natural world.
