How many kangaroos can be in a mob?

There's no fixed number for how many kangaroos can be in a mob. The size of a mob varies greatly depending on factors like:

* Region: Some areas have denser populations than others.

* Food availability: Mob size can fluctuate based on how much food is available.

* Season: Mating seasons and times of drought can influence mob size.

* Predators: The presence of predators can also affect how kangaroos group together.

Generally speaking, mobs can range from a few individuals to hundreds.

Instead of a specific number, it's more accurate to say that a "mob" is a loosely defined social group of kangaroos.
