Crab Watch

Enjoy exploring the sea shore; interested in crabs; want to contribute to ocean science? The Crab Watch app has been developed to allow you to both learn about, and submit records of, the crab species that you find on the shores around Europe.

The crab records that you submit will allow scientists to assess the distribution and abundance of both native and non-native crabs throughout Europe and assess the potential impacts that climate change and non-native species have on native populations.

The app includes a comprehensive crab identification guide featuring lots of useful information and clear photos of the most common European species, many of which are annotated to show you the key features.

Become a citizen scientist; it's simple, fun and will make a real difference to our understanding of Europe's crabs!
