It's a fish!

"In the regions along the Paraná river in Southern Brazil, Northern Argentina, and Uruguay, capybaras are frequently captured and kept as pets, or occasionally hunted for food. The flesh is described as tasting like swine and has a whitish appearance similar to pork.
"Venezuelan farmers make a valuable addition to their incomes by selling capybara meat (approximately 400 tons annually). The rodents are rounded up in February so that they can be slaughtered and sold just before the onset of Lent, when the meat is in high demand.
"This popular custom is attributed to a curious theological decision by the Catholic Church. When European missionaries first met capybaras in South America during the 16th century, they wrote to Rome for guidance, saying "there is an animal here that is scaly but also hairy, and spends time in the water but occasionally comes on land; can we classify it as a fish?" The question was significant, as the Catholic faith then forbade eating meat (other than fish) during Lent, the period of abstinence lasting 40 days before Easter. Having a second-hand description of the animal, and not wanting the petitioners to turn away from Catholicism, the Church agreed and declared the capybara a FISH — a decision that was never reversed."
Doctrine is indeed amazing.
