What term describes the dead body of an animal?

The term that best describes the dead body of an animal is "carcass." In veterinary and biological contexts, a carcass refers specifically to the remains of an animal after it has died, particularly when it is being discussed in terms of its use in veterinary pathology, butchery, or environmental studies.

The word "carcass" often implies that the body is intact and complete enough to be examined or processed, making it a specific term used regularly in both domestic and wildlife scenarios. Additionally, this term can encompass aspects related to decomposition and the ecological role of dead animals within their environment.

While "cadaver" is a term often used for dead bodies in scientific and medical contexts, particularly when the body is used for study, it usually refers to human remains. "Corpus" and "fibroid" also do not accurately capture the definition of a dead animal body; "corpus" is often used in legal contexts, and "fibroid" refers to tissue tumors. Thus, "carcass" stands out as the most appropriate term in the context of veterinary terminology.
