Hi Bing, I did LIU - here is a site which appears to have the answer. We'd better not post any recipes, otherwise the wrath of AnnaStrophic could be incurred!

The lowdown:
We have read that capybaras may be eaten by Catholics during Lent in parts of South America, because they are aquatic. We've been unable to confirm this to our satisfaction, but it's an interesting story. They are definitely eaten by humans and other large predators in any case. Fortunately, we have no pictures of this activity.

UPDATE:
According to Emilio Herrera, a biologist and capybara expert at Universidad Simon Bolivar in Caracas Venezuela:
"It is true that capybaras are eaten during Lent, but only in Venezuela, and even there not everywhere. However, its dried and salted meat is highly appreciated and is a traditional lenten dish. The annual capybara harvest is legal and regulated by government. The well-designed management plan (based on a study by Juhani Ojasti published in 1973) has been in operation for many years and is very successful, contributing income to ranchers, meat for people, and not damaging their populations."

I think the issue here is that good Catholics are lateral thinkers. In a society where there are no longer any rules, all the inventiveness which was brought into play to find a way round these relatively trivial regulations has been lost. All we are left with is tax lawyers, trying to find a loophole in the latest legal obstacle to making millions turn into billions.
