-
Norway Rats
Commonly known as sewer rats or wharf rats, Norway rats have a brown upper body, small ears, and hairless tails. Unlike other species of rats, they are not known for their acrobatic ability and found in underground basements and open fields.
Swimming, however, is their forte. They have an exceptional ability to navigate and live in sewers. They feed on cereals, seeds, meat, fish, and nuts.
-
Black Rats
Black rats, as the name suggests, have a jet-black appearance with light greyish underbellies. They are covered in fur and have a long naked tail. Unlike Norway rats, they aren’t fond of swimming.
They occupy high grounds, such as attics, rooftops, and trees, owing to their ability to climb. Their daily diet consists of grains, snails, trash, and ripe fruits.
