African vlei rats (Otomys), also known as groove-toothed rats, live in many areas of sub-Saharan Africa. They live in marshlands and grasslands, and eat the green grass and herbs that grow there, occasionally supplementing this with roots and seeds. They are named after "vlei", the local term for intermittent lakes.

They have shorter legs and tails than other types of rats, and can be various colours.[2]

African vlei rats are compact rats with short faces, short legs and a short tail. They eat grasses, seeds, roots, leaves and other similar food. Adults are between 12 and 22 cm (5–9 inches) long between head and tail, and the young are between 8 and 12 cm (3–5 inches). They weigh 90 to 260 grams (3–9 oz). Most species live in grasslands, savannas, swamps, and similar habitats.[2]
