This year, the World Register of Marine Species (WoRMS) turns 15, and they are kicking off their celebrations. Keep an eye on the WoRMS twitter (@WRMarineSpecies) and home page. On November 17th, they will start with a 15-week long series of news messages, highlighting several topics of WoRMS, a number of them from ‘behind the scenes’. They warmly welcome you to follow them on their 15-week ‘celebrating their anniversary’ adventure.
