Ctenomyidae- Tucotucos

Meet the Tuco-Tucos, which gets their name from the ‘tuc-tuc’ sound they make while they dig their burrows

Inhabiting the grasslands, forests, mountain slopes, pastures, and agricultural fields of South America, tuco-tucos are small to medium-sized animals that can weigh up to around 700 grams in body weight. Their skin is very loosely attached to their body which might be an adaptation for moving around easily in the narrow burrows that they live in.

These nocturnal rodents are primarily active between dawn and dusk, though they have been observed venturing out of their burrows on rare occasions. Each year, tuco-tucos pair off and have litters of anywhere from one to seven healthy babies.
