What characteristics are associated with a Norway rat?

Norway rats are characterized by a blunt nose, small ears relative to their body size, and a heavy body build. This robust structure is adapted for their burrowing and scavenging lifestyle.

The blunt nose is a distinctive feature that helps differentiate them from other rat species, while the smaller ears highlight that their hearing is not as acute as some other rodents that may have larger ears adapted for heightened awareness in open environments. The heavy body is significant; it allows Norway rats to withstand harsh conditions and store energy efficiently.

Understanding these physical traits helps in accurately identifying Norway rats in pest control, leading to effective management strategies.
