The urban capybaras live in the city, however, and feed on grass and water plants. The newspaper appeared amused in an update on Wednesday that the images had become an international topic of discussion given how common capybaras are to life in the region. Capybaras can grow to be as long as 4.5 feet and two feet tall, and weigh up to 150 pounds. The report mentioned that the capybaras were already a common sight in the Mato Grosso Legislative Assembly’s reflecting pool. “The law protects capybaras, and that’s becoming a challenge for cities,” environmental lawyer Felipe Neves Linhares told the outlet.
