Hi there! Have you ever wondered why some animals eat their own babies? It might sound strange, but there’s actually a reason behind this behavior. Let’s explore why animals like hamsters, pigs, insects, birds, snakes, primates, and fish sometimes do this.
For most animals, having babies is super important because it’s how they pass on their genes to the next generation. So, why would they eat their own young? It seems like the opposite of what they should do, right? Well, it turns out that in some situations, this behavior can actually help the animals survive and thrive.
Take hamsters, for example. Sometimes, a mother hamster has too many babies to take care of. If she has more babies than she can handle, she might eat a few to make sure the rest get enough food and attention. Scientists have found that if they add extra babies to a hamster’s litter, the mother might eat even more of them. But if they take away a few babies right after they’re born, the mother is less likely to do this. This shows that hamster moms are trying to make sure their babies have the best chance of surviving.
Other animals might eat their young only in emergencies. For instance, the Long-tailed Sun Skink, a type of lizard, might eat her eggs if a predator is nearby. By doing this, she can save her energy and be ready to lay more eggs in the future when it’s safer.
Then there’s the male sand goby, a fish that takes care of eggs from different females in one nest. He needs to wait for all the eggs to hatch before he can mate again. If some eggs are developing too slowly, he might eat them to speed up the process and get back to reproducing sooner.
In the animal kingdom, making sure their genes are passed on sometimes means making tough choices. By eating some of their young, these animals can maximize their resources and increase their chances of having more babies in the future. It’s a fascinating and sometimes surprising part of nature!
Draw a comic strip that illustrates the reasons why certain animals might eat their young. Use characters like a hamster, a lizard, and a fish to show different scenarios. This will help you visualize and understand the concept better.
In groups, act out a scene where you are animals making decisions about your offspring. Discuss as a group why you might choose to eat your young in certain situations. This will help you empathize with the animals’ tough choices.
Pick an animal from the article and research more about its behavior. Create a short presentation to share with the class, explaining why this animal might eat its young and how it benefits their survival.
Hold a debate on the ethics of animals eating their young. Split into two groups: one supporting the behavior as a survival strategy and the other opposing it. This will help you think critically about the topic.
Write a short story from the perspective of an animal that eats its young. Describe the situation and emotions involved. This will help you explore the concept creatively and understand the animal’s perspective.
Sure! Here’s a sanitized version of the transcript:

Hi, this is Emily from MinuteEarth. Sometimes, a hamster mother looks at her adorable little babies and thinks, “I just want to take care of you”—except in a more concerning way. Hamster mothers are not alone; other animals like pigs, insects, birds, snakes, primates, and fish occasionally exhibit similar behaviors towards their young.
This is intriguing, not just because humans generally find it unacceptable to harm their own offspring, but also because reproduction is the primary goal of nearly all life. Therefore, consuming their young seems counterproductive. However, self-defeating behaviors typically diminish over time, so the fact that various species sometimes engage in this behavior suggests it can be a successful strategy.
For example, hamsters appear to use this behavior as a form of population control: females with larger litters tend to reduce the number of pups they care for. When scientists add extra pups to a litter, the mothers may consume even more. Conversely, removing a few pups shortly after birth can prevent this behavior, indicating that a hamster mother may reduce her litter size to ensure the remaining pups receive adequate care and have a better chance of survival.
Other animals, like the Long-tailed Sun Skink, may consume their young only in emergencies. When predators threaten the mother’s eggs, she may choose to eat them herself. This can be a strategic move, as it allows her to prepare for future reproduction.
Additionally, in the case of the male sand goby, he fertilizes eggs from multiple females and cares for them in one nest. To mate again, he must wait for all the eggs to hatch, so he may sacrifice some of the slower-developing eggs to free himself for more reproduction.
In summary, for various species in the animal kingdom, maximizing resources and opportunities to pass on their genes sometimes leads to difficult decisions regarding their young.

This version maintains the core ideas while removing any inappropriate language or implications.
Animals – Living organisms that can move and respond to their environment, usually having specialized sense organs and nervous systems. – In biology class, we learned that animals like lions and zebras live in the African savanna.
Behavior – The way in which an organism acts in response to a particular situation or stimulus. – The behavior of birds changes during migration as they travel long distances to find food and warmer climates.
Babies – The young offspring of an organism, especially those that are newly born. – In the spring, many animals have babies, and the mother deer carefully watches over her fawns.
Survive – To continue to live or exist, especially in spite of difficult conditions. – Plants and animals have adapted in various ways to survive in harsh desert environments.
Hamsters – Small rodents often kept as pets, known for their cheek pouches and burrowing habits. – In our science project, we observed how hamsters store food in their cheeks to save for later.
Emergencies – Sudden, urgent, usually unexpected occurrences requiring immediate action, especially in a biological context. – Animals have instincts that help them react quickly to emergencies, such as escaping from predators.
Predator – An animal that naturally preys on others for food. – The cheetah is a fast predator that relies on its speed to catch prey in the wild.
Strategy – A plan of action designed to achieve a long-term or overall aim, often used by organisms to survive or reproduce. – Some animals use camouflage as a strategy to avoid being seen by predators.
Genes – Units of heredity that are transferred from parents to offspring and determine some characteristics of the offspring. – The genes inherited from their parents can influence a person’s eye color and height.
Resources – Materials or substances such as food, water, and shelter that organisms need to survive and grow. – In a forest ecosystem, trees provide resources like food and shelter for many animals.
