What Do Zoos Do with Dead Animals? The Circle of Life Behind the Scenes

Globally, zoos play a vital role in conservation efforts and educating the public about endangered species. However, have you ever wondered what happens when an animal in a zoo passes away? In my years working in the zoo industry, I have gained insights into the delicate process of handling dead animals. In this guide, I will take you behind the scenes to explore the circle of life in zoos, shedding light on the ethical and practical considerations involved in managing deceased animals. From post-mortem examinations to disposal methods, I will give you an inside look into what zoos do with dead animals, and how it contributes to the wider ecosystem.

Key Takeaways:

  • Respectful practices: Zoos typically handle the death of their animals with care and respect, often holding respectful memorial services to honor the deceased animals.
  • Educational opportunities: Dead animals in zoos are often utilized for educational purposes, such as scientific research or as teaching tools for visitors.
  • Contribution to conservation: Some deceased zoo animals are used for conservation efforts, such as providing specimens for genetic studies or wildlife preservation programs.
  • Compassionate care: Zoo staff often go above and beyond in providing compassionate care for their animals in their final days, ensuring they are comfortable and well-cared for.
  • Environmentally responsible disposal: Zoos prioritize environmentally responsible disposal methods for deceased animals, such as composting or utilizing the remains for animal feed.

The Disposal Process at Zoos

Before I delve into the details of what happens to deceased animals at zoos, it’s important to note that every zoo may have its own unique protocols in place for the disposal of their deceased animals. These protocols are usually in line with local, state, and federal regulations.


At some zoos, burial is the method of choice for disposing of deceased animals. The process typically involves digging a deep grave on zoo grounds away from public view. The carcass is then placed in the grave, covered with soil, and a marker is often placed to indicate the animal’s final resting place. While burial is a respectful way to handle the remains, it’s important to note that certain large animals may pose environmental concerns if buried, due to potential contamination of soil and groundwater.


Cremation is another method used for the disposal of animals. This method involves incinerating the remains at high temperatures until only ashes remain. The ashes are then often scattered in a designated area on zoo grounds or returned to the animal’s native habitat if feasible. Cremation is a popular choice for smaller animals and can be an efficient, sanitary, and space-saving method of disposal.

Donation for Research and Education

In some cases, zoos may opt to donate the remains of deceased animals for research and educational purposes. This can include providing carcasses to universities, museums, or other institutions for study. By donating remains, zoos can contribute to valuable scientific research and educational initiatives. However, it’s important to ensure that proper protocols are followed to handle and dispose of the remains in a safe and respectful manner. This option can also pose certain risks if the remains are not handled properly.

In each of these methods, zoos prioritize respectful and ethical handling of deceased animals, making decisions based on the particular circumstances and in compliance with the pertinent regulations.

The Ethical Considerations

Some ethical considerations arise when dealing with the bodies of deceased zoo animals. As a zoo professional, I am tasked with ensuring that the remains of these animals are handled in a respectful and responsible manner. This involves weighing the ethical implications of various methods of disposal and considering the impact on staff, visitors, and the environment.

Factors Influencing the Decision

When determining how to handle the remains of a deceased zoo animal, several factors come into play. These include the size and species of the animal, the cause of death, and the zoo’s available resources. Additionally, the emotional attachment of staff and visitors to the animal can also influence the decision-making process. Recognizing the ethical responsibility to honor the animal’s life, we carefully consider the most appropriate course of action.

Pros and Cons of Various Methods

There are various methods for handling the deceased bodies of zoo animals, each with their own set of pros and cons. It’s important to consider factors such as the ecological impact, emotional toll on staff, and potential public perception. Below is a table summarizing some of the main pros and cons of common disposal methods:

This process ensures that the deceased animals are handled with care and respect, while also minimizing the impact on the environment. Zoos work closely with licensed vendors and disposal facilities to ensure that the remains of the animals are managed in a responsible manner.

  • Consider environmentally-friendly methods: Explore options for environmentally-friendly disposal methods, such as composting or natural decomposition.
  • Follow established guidelines and regulations: Adhere to all relevant guidelines and regulations set forth by local authorities and animal welfare organizations.

Recognizing the importance of ethical and sustainable disposal practices will not only benefit the zoo and its animals, but also contribute to broader conservation and environmental efforts.
