I had no idea that there were hairy snails, but here is a German hairy snail, and it lives in the Thames in London (having arrived during the last Ice Age when the UK and the rest of the European continent were connected by land).

For any Londoners out there, this book is great - a lovely exploration of the nature that exists in the city and where to find it: https://www.wildlondon.org.uk/news/announcing-our-new-book-london-wild-exploring-nature-city
