To wit, one of my friends (James Lin, of Lincoln Highway fame) has just forwarded me an article from the New York Times about the world's most delicious rodent (I bet Amazon's statistically improbable phrases would have fun with that one). As you can see in the picture below, it's pretty obvious that capybara aren't fish.
So here's the Gray Lady on rodent-fish:
The annual hunt comes before Easter, when capybara has a status in Venezuela similar to that of turkey during Thanksgiving. While the Roman Catholic Church generally forbids eating meat during certain days of Lent, many Venezuelans insist that the capybara is more akin to fish than to meat.
That may have something to do with how salted capybara tastes, resembling a mixture of sardines and pork. Legend has it that eating capybara, known here as chigüire (pronounced chee-GWEE-reh), got a boost in the 18th century when the local clergy asked the Vatican to give capybara the status of fish.
