Are hyenas scavengers12/24/2023 ![]() ![]() Jackals may travel long distances over open plains in search of food and mates. The strong legs and feet are well adapted for digging holes and climbing. Jackals can run fast, up to 60 kilometers per hour for a short distance, and are good jumpers. Jackals will follow other scavengers, like vultures, to find their next meal! Its long, narrow muzzle, eyes and ears, and bushy tail are adaptations for nocturnal hunting. ![]() The jackal’s skull, with powerful jaws, short snout, and broad forehead, is adapted for hunting small mammals and birds. Their diet changes between seasons, as different food types become more abundant, or as they grow bigger and can handle larger food items like hares and deer. In the wild, they mainly eat rodents, small mammals, and carrion but also grasses and fruit. Jackals are opportunistic feeders that will eat anything they can get. Whereas they mostly eat living things like rodents and small mammals, they do also eat dying or dead animals. Jackals are primary predators but can function as scavengers on the land. In the wild, they form an important part of the food web since they eat a wide variety of food items and provide a nutritious meal to larger predators or scavenger animals.

This questionoriginally appeared on Quora. It's possible that the reason why eating meat became more hazardous (eating fruits also) is because factory farming favors increased numbers of pathogens and also more opportunities for contamination. It is quite possible that we would actually not do too badly if we had to feed on rotting meat. Or perhaps as a species we have a higher number of fecal-oral pathogens that can specifically infect us and kill us, and natural selection may have favored high stomach acidity. It has been postulated that eating rotten meat was part of our evolutionary history. Interestingly, the human average, at pH of 1.5, is lower than other omnivores such as baboons, pigs, mice and rats, and it is similar to the acidity in scavengers. ![]() Unfortunately, the hyena is not one of them, but the lowest pH levels on that table are the scavengers and carnivores, and the highest pH are herbivores like kangaroos, llamas and colobus monkeys. The article contains a table listing of the stomach pH of all the animals included in the study. This reduces the chances of food remaining longer on the intestinal tract and allowing pathogenic bacteria to multiply. Also notice that scavengers and carnivores have shorter guts than omnivores or herbivores. ![]() Their findings support the hypothesis of stomach pH as a biological filter for pathogenic bacteria. The highest pH (lowest acidity) should be present in the stomachs of herbivores, as they are exposed to the lowest levels of potentially pathogenic bacteria. The authors gathered data from sixty-eight mammals and birds, including herbivores, omnivores (humans are omnivores), carnivores that eat prey phylogenetically related to them, and carnivores that eat prey phylogenetically distant to them (for example, insects) hypothesizing that the stomachs of scavengers will have the lowest pH, followed by carnivores that are also facultative scavengers, and then omnivores and carnivores that eat prey more distantly related to them, such as insectivores. A meta analysis of the acidity of the stomach of various mammals and birds was published recently, testing the hypothesis that gastric acidity is a filter to avoid gut colonization by pathogenic bacteria. ![]()
