How much space (in square feet) does a giant anteater need? This is in
the context of say an anteater exhibit. This is hypothetical--I'm not
really going to capture a giant anteater.

I need a reference with the following contraint: if the information
comes from a website, then the domain must be either .gov, .org, or
.edu.

Hi Iconjack,

According to the California Department Of Fish And Game,
Restricted Species Laws And Regulations:
Importation, Transportation And Possession Of Wild Animals - Manual 671
the minimum requirements for housing Giant Anteaters is 200sq ft for
the first animal +100sq ft/animal thereafter with a minimum height 6ft
ceiling.

In the wild their ranges may be as large as 9000 hectares.

Thanks hardtofindbooks, this is a good answer.
I'm wondering why you submitted it as a comment.

Commenters with black names cannot post an official answer  - which in
no way lessens the appropriateness and accuracy of the information in
some comments  (a great many by Hardtofindbooks  :-).

Only official G-A Researchers, whose names appear in blue, can
"answer" a question, but they will not repost information from a
satisfactory comment, so it looks like you saved some money.
