Rattus rattus

Rattus rattus, commonly known as the black rat or roof rat, is a medium-sized rodent with a slender body, long tail, and large ears. Native to Asia and Africa, it has spread worldwide, often inhabiting urban and rural areas. Black rats are highly adaptable, thriving in buildings, crops, and sewers. They are nocturnal and skilled climbers, frequently nesting in high places. They can carry and transmit diseases to humans and animals, and may cause damage by gnawing on structures and food supplies. Their presence can pose health risks and economic impacts, making pest management important where they are found.
