* "Largest of families" is ambiguous: Do you mean:
* Largest in terms of body size? If so, the yellow-footed rock wallaby is a fairly large species of wallaby, but there are other macropods (kangaroos, wallabies, etc.) that are larger.
* Largest in terms of family size? This is difficult to determine, as animal families can have variable litter sizes and lifespan, making it hard to compare across species.
* Largest in terms of population? Again, it's hard to say definitively as population data for specific species can be difficult to collect.
To give a better answer, we need more clarification on what you mean by "largest of families."
For example:
* If you're interested in the largest macropods, you could look at the red kangaroo or the antilopine kangaroo.
* If you're interested in family size in a specific context (e.g., how many young a yellow-footed rock wallaby typically has), you'll need to research that particular species.
