Today at National Museum Cardiff we are celebrating the very first International Polychaete Day, held in honour of a great polychaetologist, Kristian Fauchald who sadly passed away on the 5th April this year. Today would have been his 80th birthday, and museums and scientists are celebrating the wonderful diversity of marine bristleworms across the globe.

Polychaetes or marine bristleworms are a diverse group of segmented worms related to earthworms and leeches, and are abundant in marine and estuarine environments. Often the dominant animals living in seabed environments, they have important roles in marine food chains and reprocessing of nutrients, but are also indicators of the health of seabed habitats. The Museum has been carrying out research into this fascinating group since the 1980s and is the largest repository of Welsh polychaetes globally.

In honor of the day, we have published a story of our #WormWednesday Tweets for the last six months and we have been tweeting via the #InternationalPolychaeteDay hashtag.

Why not follow @CardiffCurator to find out more or read our Storify about the day's events on social media.

Inspired by Kristian's famous 'Pink Book' for identifying polychaete worms everywhere, we have today released a special pink version of the logo for the 12th International Polychaete Conference, which will be held at the museum next August.
