What is it?

The World Register of Introduced Marine Species (WRIMS) records which marine species in the World Register of Marine species (WoRMS) have been introduced deliberately or accidentally by human activities to geographic areas outside their native range. It excludes species that colonised new locations naturally (so called ‘range extensions’), even if in response to climate change.

How it can help?

Includes more than 1400 introduced species worldwide. Lists the known alien marine species worldwide, with an indication of the region in which they are considered to be alien. Also lists whether a species is reported to have ecological or economic impacts and thus considered invasive in that area.
