Conservation

Along with other marine organisms, sea squirts are transported around the world via anthropogenic activities. Some - like Corella eumyota - establish and disperse in non-native areas and become unwelcome invasive species causing serious ecological problems by:

  • competing and interfering with native fauna and hence
  • posing a potential threat to local biodiversity

And causing substantial financial loss to mussel and oyster aquaculture by:

  • competing for space and food resources
  • reducing water flow and oxygen

There are about 60 established non-native marine species in UK waters. Obtaining records of non-native species occurrence and abundance helps:

  • track changes in distribution
  • assess their impact on our native fauna and flora

You can report sightings of Corella eumyota in marinas and other sites on the Marine Life Information Network website.
