Golfers at the Rio Olympics have more than just sand traps to worry about.
The world’s largest rodents, the capybara, which can weigh up to 150 pounds, have been spotted at the Olympic Golf Course, NBC reports. The course is located in the Barra da Tijuca region of Rio, built along the edge of a nature preserve despite protests from environmental activists.
This area is home to many exotic animals including monkeys, boa constrictors, owls (many of whom have burrowed holes in some of the course bunkers) and three-toed sloths, but it’s the capybara getting the most attention.
While 40 of the giant, vegetarian rodents were removed from the Olympic course, many still remained and have caught the attention of players. Some golfers, including Spain’s Sergio Garcia, have even stopped practice rounds to take pictures.
