What is another name for a animals pouch?

There isn't one universal "other name" for an animal's pouch, as the term itself is fairly specific. However, depending on the context, you could use these terms:

* Marsupial pouch: This is the most accurate term, especially when talking about the pouch of marsupials like kangaroos and koalas.

* Abdominal fold: This is a more general term that refers to any fold of skin in the abdomen, including pouches.

* Pocket: While not strictly scientific, "pocket" can be used in a casual context to describe the pouch.

Ultimately, the best term to use depends on the specific situation and the audience.
