In this brief article we will answer the questions: which animals are most likely to eat a relative, why is it likely to eat a relative, and how it can possibly be avoided. 

Which animal is most likely to eat a relative?

There are various species of animals that eat their own kind. They include:

Sand tiger sharks. 

These are types of sharks that vary from the white sharks in fin differentiation. It is a gray and spotted ragged-tooth shark. It is common in subtropical and temperate water. They swim to a depth of 191 meters. 

The younger large siblings feed on the smaller younger siblings while in gestation. These sharks are also found in the mediterranean sea. It is a docile shark and has no recorded human fatalities. It is an ardent swimmer and has a fearsome look. 

Polar bears. 

These are a variation of the grizzly bear, they are white furred. They are common in the Antarctic and in the more cold areas. They feed on fish, seals, penguins and can also attack humans. They feed on their young ones due to food scarcity. 


These are arachnids that possess a pair of antennae and a pair of four legs. They reproduce by sexual reproduction where the female lays fertilized eggs that hatch to young spiders. The female spiders often feed on the male spider after mating. The most common is the black widow spider. 


These are slightly larger rodents. They are kept as pets as they are considered cute and cuddly. They reproduce fast and a female hamster gives birth to at least six newborns. They tend to feed on and kill newborns especially if they are touched by the owner. The scent confuses them and they tend to think that the newborns are food handed to them. 

Parasitic wasps. 

They are a big family of the Hymenopteran species. They reproduce by laying one male and one female egg in the bodies of caterpillars. These eggs clone themselves to as many as possible. Once hatched the females eat up the males until only few are left. Only a few males are needed for reproduction. 


Hens are omnivorous and are opportunistic feeders of meat. They are known to eat eggs. They are also known for feeding on hens that have a prolapse of the cloaca when laying. Male chickens also regularly fight and may lead to cannibalism. 

Tiger salamanders. 

These are terrestrial species of the mole salamanders. They grow to an average of 7 inches. They are brightly colored in green and black. There are other species with a variation in color. 

They have been widely studied. They are mainly found in North America. Their larva is developed into two, non-cannibal morph and cannibal morph. Non-cannibal morph feeds on small aquatic invertebrates while the cannibal morph feeds on the non-cannibal morph. 


Lions are carnivorous animals also known as Panthera leo. They are pride animals. New male lions in a pride tend to kill young male cubs. Young cubs can get lucky and reach maturity. They are then sent off to go and search for a new pride. 

Why are animals likely to eat their relatives?

Animals feed on their relatives due to lack of enough food. For example in the case of polar bears they feed on their young due to lack of food like seals and fish. 

They also feed on each other to prevent competition of resources such as mates, food, and habitat. They also kill young ones as they perceive them as foriegn as they have interacted with other pheromones. 

They also cannibalize to control overpopulation. 

How can it possibly be avoided?

In the wild, cannibalism is hard to control but in tamed animals it is easy. For domestic animals cannibalism can be avoided in the following ways:

  • Not touching young ones. This reduces the chances of the mothers killing the young ones. 
  • Providing ample food, to avoid competition and fights over food. 
  • Control of the lighting of the houses especially for the chicken to prevent them from eating eggs and pecking each other.
