The world's largest known rodent, the capybara, was spotted by workers at the Paso Robles Wastewater Treatment Plant and photographed before submerging back into the water, reported Fox 35. "I received a call from the city of Paso Robles sewer plant," Tom Tognazzini of the Department of Fish and Game told Your Central Coast News. This gigantic capybara is believed to weigh between 100-120 lbs. _"A capybara was consuming vegetation in the sewer ponds. It actually worked its way from south to north along each pond strip," he said. This is reportedly the third sighting of a capybara in the Paso Robles area in three years and officials say it might be the same one.
