Introduced Species Observations Map: Last Updated: 2025-02-11









Welcome to the Marine Introduced Species map! This interactive map is meant to serve as an accessible platform for researchers, resource managers and the general public who are concerned with the spread of marine introduced species to track their spread. We rely on scientists and community members to report observations of introduced marine species to keep this map current. This information is used to understand how these species are spreading, how scientists should focus their research to learn more about them, and where resource managers should focus their control efforts.

The scope of this map includes the area along the eastern Pacific coast of North America. When the exact date of the observation is unknown, the first day of the month is displayed.
