* Species variation: There are many different species of opossums, and their stomach sizes will vary.
* Individual variation: Like any animal, opossums vary in size, and their stomach size will reflect that.
* Limited research: There isn't a lot of research focused specifically on the dimensions of opossum stomachs.
What we do know:
* Omnivorous diet: Opossums are omnivores and have a stomach adapted to digesting a wide range of foods.
* Large capacity: Their stomachs are known for being able to hold a large volume of food, as they are opportunistic eaters.
Instead of a specific measurement, you might be interested in these facts:
* Opossums eat up to 40% of their body weight in a single night! This emphasizes their capacity for large meals.
* Their digestive system is fast-acting. They can digest food quickly to make room for more.
