That computer voice is awful, could have sworn I heard "carcaruga", and now I feel dumb. So, thanks robot.
Really weird, look's like with the narrator of the YouTube channel Fatos Desconhecidos.
...we often call tortoise "tartaruga", but technically, "tartaruga" is that living in water (the most common way to refer to them is "tartaruga marinha -- turtle of the sea", and "cágado" is that living on land.
So, turtle = tartaruga, tortoise = cágado, but often cágado is called tartaruga.
