The ship rat, also known as the black rat or Rattus rattus, is a small rodent that is commonly found in urban areas and aboard ships. These agile creatures are typically dark brown or black in color and have long tails. They are known for their ability to climb and are often found in attics, warehouses, and other high places. Originally from Southeast Asia, ship rats spread across the world, often traveling on ships during trade. They are notorious for their role in spreading diseases, including the bubonic plague, which had devastating effects on human populations in the past. Their adaptability makes them a common pest in many regions.
