Non-native Marine Invertebrate Workshop
Yesterday Anna Holmes, the Curator of Invertebrate Biodiversity at the National Museum of Wales, came to PLANED to talk to various organisations about invasive invertebrate species that are attaching themselves to plastic marine waste and rafting across the oceans to be washed up on our shores.
Anna brought examples of these invasive species, you can see that the zebra mussel shown here has a large notch in one end (which, as you may well know, our native species don’t have), this is a species from the Caribbean which floated over to this country attached to a piece of plastic.
It was a fascinating presentation and discussion about the dispersion of animals on ocean currents. Anna showed us many more examples of invasive species as well as some of the items to which they were attached. At the end of the workshop Anna showed us how to use the various online databases to identify and also report any findings.
I talked to Anna after the event and we are hoping to run some more activities on finding and identifying non-native species around the coast of South West Wales. She might even do a podcast …
