Cricetomys is a genus of large rodents commonly known as giant pouched rats. They are native to Africa and are recognized for their distinctive cheek pouches, which they use to store food. These rodents typically inhabit grasslands and forests, where they play a vital role in their ecosystems by helping to aerate the soil and disperse seeds. Giant pouched rats are known for their intelligence and adaptability. They have been trained for various tasks, including detecting landmines and diseases like tuberculosis. Their keen sense of smell and ability to learn complex tasks make them valuable in both conservation and humanitarian efforts.
