The outrageous "baby-eating" behaviors in the animal world

This is very common in fish, and many fish will eat the eggs they lay. One theory is that fish eat eggs under harsh environmental conditions to obtain more energy to ensure their survival and future mating; another theory is that fish will eat some eggs moderately according to the degree of environmental tolerance, so that other offspring can develop better.

Another common "baby" eating behavior will occur in group mammals. In a lion group, a group consists of leading males, multiple females and larvae. Once the leading male is replaced, the newcomer may kill the cubs that do not belong to him. On the one hand, some females do not tend to mating when their cubs exist, and they can only reproduce by killing the original ones; on the other hand, they hope that the newcomer can devote more resources to their offspring.

Will polar bear eat their cubs?

Will! In harsh environments, when food is lacking, the polar bears will be forced to eat their cubs so that other cubs can survive first. After all, if they do not eat for a long time, the polar bear mother will not have breastfeeding offspring, and can only eat the thinnest one, solve their food and clothing, and then feed other small polar bears. The artificially raised polar bears are even more sensitive. An incident in which a female polar bear ate her cub in the Nuremberg Zoo in Germany caused a huge sensation in the local area. Under huge public pressure, Nuremberg Zoo had to abandon its original policy and instead separate polar bear cubs from the female bear and feed them artificially. The zoo announced that the little polar bear is in good condition at present. Not long after this incident, another female bear, Weira, may have been affected, and kept throwing her biological flesh and blood in her mouth to the ground, causing the life safety of the newly born little polar bear to be seriously threatened. The Nuremberg Zoo failed to actively intervene to save the bear, which attracted dissatisfaction and criticism from all parties. According to the zoo keeper, polar bears are a very sensitive animal and may abandon their flesh and blood if they are slightly disturbed. Of course, the actual situation remains to be verified.
